In this technical guide, you’ll learn everything there is to know about electric scooter batteries, including types, capacity ratings, how to prolong battery life, and proper use and storage. Electric Scooter Batteries The battery is your electric scooter’s “fuel tank.” It stores the energy that is consumed by the DC motor, lights, controller, and other accessories. Most electric scooters will have some type of lithium ion-based battery pack due to their excellent energy density and longevity. Many electric scooters for kids and other inexpensive models contain lead-acid batteries. In a scooter, the battery pack is made of individual cells and electronics called a battery management system which keeps it operating safely. Bigger battery packs have more capacity, measured in watt hours, and will let an electric scooter travel further. However, they also increase the size and weight of the scooter — making it less portable. Additionally, batteries are one of the most expensive components of the scooter and overall cost increases accordingly. E-scooter battery packs are made of many individual battery cells. More specifically, they are made of 18650 cells, a size classification for lithium ion (Li-Ion) batteries with 18 mm x 65 mm cylindrical dimensions. Each 18650 cell in a battery pack is fairly unimpressive — generating an electric potential of only 3.5 volts (3.5 V) and having a capacity of 3 amp hours (3 A·h) or about 10 watt-hours (10 Wh). To build a battery pack with hundreds or thousands of watt hours of capacity, many individual 18650 Li-ion cells are assembled together into a brick-like structure. The brick-like battery pack is monitored and regulated by an electronic circuit called a battery management system (BMS), which controls the flow of electricity into and out of the battery. Lithium Ion Li-Ion batteries have excellent energy density, the amount of energy stored per their physical weight. They also have excellent longevity meaning that they can ...

Introduction LiFePO4 chemistry lithium cells have become popular for a range of applications in recent years due to being one of the most robust and long-lasting battery chemistries available. They will last ten years or more if cared for correctly. Please take a moment to read these tips to ensure you get the longest service from your battery investment. Tip 1: Never over charge/discharge a cell! The most common causes for premature failure of LiFePO4 cells are overcharging and over-discharging. Even a single occurrence can cause permanent damage to the cell, and such misuse voids the warranty. A Battery protection System is required to ensure it is not possible for any cell in your pack to go outside its nominal operating voltage range,In the case of LiFePO4 chemistry, the absolute maximum is 4.2V per cell, though it is recommended that you charge to 3.5-3.6V per cell, there is less than 1% extra capacity between 3.5V and 4.2V. Over charging causes heating within a cell and prolonged or extreme overcharging has the potential to cause a fire. AIN Works Takes no responsibility for any damages caused as a result of a battery fire. Over charging may occur as a result of. Lack of a suitable battery protection system Faulty of infective battery protection system incorrect installation of the battery protection system AIN Works takes no responsibility for the choice or use of a battery protection system. At the other end of the scale, over-discharging can also cause cell damage. The BMS must disconnect the load if any cells are approaching empty (less than 2.5V). Cells may suffer mild damage below 2.0V, but are usually recoverable. However, cells which get driven to negative voltages are damaged beyond recovery. On 12v batteries the use of a low voltage cutoff takes the place of ...

In the actual use of batteries, high voltage and large current are often required, which need to connect several single batteries in series or parallel (or both), we call it battery pack. The 18650 lithium battery pack needs a certain standard. 1.The Meaning of 18650 Battery Pack in Series and Parallel 18650 battery in series: When multiple 18650 lithium batteries are connected in series, the battery pack voltage is the total of all battery voltage, but the capacity remains unchanged. Schematic Diagram of 18650-4S Connection 18650 battery in parallel: If you connect multiple 18650 lithium batteries in parallel, you can get more power. The parallel connection of lithium battery keeps the voltage constant, while the capacity increases. The total capacity is the sum of the total capacity of all single lithium batteries. Schematic Diagram of 18650-4P Connection Series and parallel connection of 18650 battery: the method of series and the parallel connection is to connect several lithium batteries in series and then connect the battery packs in parallel. It not only improves the output voltage, but also the capacity. 18650-2S2P Connection Diagram 2.Precautions for Series and Parallel Connection of 18650 Lithium Battery Series and parallel connection of lithium batteries need battery cell matching. Lithium battery matching standards: voltage≤10mV resistance ≤5mΩ capacity≤20 mA Battery with the same voltage Different batteries have different voltages. After being connected in parallel, the high-voltage battery charges the low-voltage battery, which consumes the power and may lead to accidents. Battery with the same capacity Connect batteries with different capacities in series. For examples, same battery may be different from the aging degree. Batteries with small capacity will fully discharge first, then the internal resistance will increase. You also need to use the same battery if connect in series. Otherwise, after connecting batteries with different capacities in series (for example, same battery ...

Safety is a full-fledged design feature with lithium batteries, and for good reason. As we’ve all seen, the chemistry and energy density that allows lithium-ion batteries to work so well also makes them flammable, so when the batteries malfunction, they often make a spectacular and dangerous mess. All lithium chemistries are not created equal. In fact, most American consumers – electronic enthusiasts aside – are only familiar with a limited range of lithium solutions. The most common versions are built from cobalt oxide, manganese oxide and nickel oxide formulations. First, let’s take a step back in time. Lithium-ion batteries are a much newer innovation and have only been around for the last 25 years. Over this time, lithium technologies have increased in popularity as they have proven to be valuable in powering smaller electronics – like laptops and cell phones. But as you may recall from several news stories over recent years, lithium-ion batteries also gained a reputation for catching fire. Until recent years, this was one of the main reasons lithium wasn't commonly used to create large battery banks. But then came along lithium iron phosphate (LiFePO4). This newer type of lithium solution was inherently non-combustible, while allowing for slightly lower energy density. LiFePO4 batteries were not only safer, they had many advantages over other lithium chemistries, particularly for high power applications, such as renewable energy. Before we dive into the safety features of lithium iron phosphate, let’s refresh ourselves on how lithium battery malfunctions happen in the first place. Lithium-ion batteries explode when battery’s full charge is released instantly, or when the liquid chemicals mix with foreign contaminants and ignite. This typically happens in three ways: physical damage, overcharging or electrolyte breakdown. For example, if the internal separator or charging-circuitry is damaged or malfunctions, then there are no ...

A vacuum cleaner battery is a very important part of every portable cordless vacuum cleaner. Even if you have a vacuum cleaner with the best characteristics on paper, but your battery pack is failing quickly, you will not be satisfied with your cordless vacuum cleaner as a whole. Batteries as replacement parts for vacuum cleaners. You can buy them from online stores or in shops specialized for electronic equipment or shops with vacuum cleaner spare parts. Before buying cordless vacuum batteries, there are several things you should know about them. Can a Rechargeable Vacuum Cleaner Battery Die? Yes, rechargeable batteries die, too. Depending on their chemistry type, rechargeable batteries – even when treated properly – can withstand only a limited number of charging/discharging cycles. For example, deep cycle lead-acid batteries (these are NOT common car starting batteries) and nickel-cadmium batteries can endure a few hundred charging/discharging cycles. Nickel metal hydride batteries can stand up to 500 cycles, while various lithium batteries ‘operate properly’ even after 1000 charging/discharging cycles. When the batteries are not treated properly, their life span shortens significantly and they simply die! Note Operate properly means that after some time all batteries lose their capacity, but this is within certain limits, according to various standards. The best tester is, You, consumer – if your vacuum is not performing as it did when you bought it due to failing battery pack, it is time to change the batteries. Always read manuals of your cordless vacuum cleaners. Which handheld vacuum cleaner or backpack vacuum cleaner (or any other type of battery-powered vacuum cleaner) you have, it determines which replacement battery you will have to purchase. Read and write down the exact replacement part ID number of your battery and of course which vacuum cleaner you have. This way you will certainly buy a ...

Lithium batteries stand apart from other battery chemistries due to their high energy density and low cost per cycle. However, "lithium battery" is an ambiguous term. There are about six common chemistries of lithium batteries, all with their own unique advantages and disadvantages. For renewable energy applications, the predominant chemistry is Lithium Iron Phosphate (LiFePO4). This chemistry has excellent safety, with great thermal stability, high current ratings, long cycle life, and tolerance to abuse. Lithium Iron Phosphate (LiFePO4) is an extremely stable lithium chemistry when compared to almost all other lithium chemistries. The battery is assembled with a naturally safe cathode material (iron phosphate). Compared to other lithium chemistries iron phosphate promotes a strong molecular bond, which withstands extreme charging conditions, prolongs cycle life, and maintains chemical integrity over many cycles. This is what gives these batteries their great thermal stability, long cycle life, and tolerance to abuse. LiFePO4 batteries are not prone to overheating, nor are they disposed to 'thermal runaway' and therefore do not over-heat or ignite when subjected to rigorous mishandling or harsh environmental conditions. Unlike flooded lead acid and other battery chemistries, Lithium batteries do not vent dangerous gases such as hydrogen and oxygen. There's also no danger of exposure to caustic electrolytes such as sulfuric acid or potassium hydroxide. In most cases, these batteries can be stored in confined areas without the risk of explosion and a properly designed system should not require active cooling or venting. Lithium batteries are an assembly composed of many cells, like lead-acid batteries and many other battery types. Lead acid batteries have a nominal voltage of 2V/cell, whereas lithium battery cells have a nominal voltage of 3.2V. Therefore, to achieve a 12V battery you'll typically have four cells connected in a series. This will make the nominal voltage of ...

Lead-acid RV batteries may still dominate the market, but many RV adventurers are moving to lithium batteries instead because they're a superior alternative to traditional batteries. The benefits of choosing LiFePO4 over lead-acid for any application are numerous. And, when it comes to your RV, there are specific advantages that make lithium RV batteries the ideal choice. 1. They’re safe.Your RV isn’t just a means to get from point A to point B during your vacation. It’s your vehicle and your home. So, safety matters. LiFePO4 RV batteries are designed with a built-in safety measure. When they near overheating temperatures, these batteries automatically shut down, preventing fire or explosion. Lead acid batteries, on the other hand, typically don’t include this fail-safe measure and are sometimes susceptible to fire when they come into contact with foreign metals. No battery is perfect, but ALL IN ONE lithium batteries are the safest choice on the market. 2. They go further.Your typical lead-acid RV battery only allows you to use around 50% of the rated capacity. Lithium batteries are ideal for extending dry camping wherever your travels take you. With highly sustainable voltage levels, your lithium RV battery offers 99% usable capacity which gives you that extra time in your home away from home. 3. They weigh less. Your RV is big enough and heavy enough as it is. Lithium batteries are typically half the size and a third of the weight of traditional lead-acid batteries. Reduce the weight of your vehicle and increase the capacity for speed. 4. They live longer. Battery life span matters. Would you rather replace a lead-acid battery once every two or three years, or would you rather make an investment in a lithium battery that lasts over a decade? Lithium batteries have up to 10X longer cycle life than lead-acid ...

The golf cart battery industry is in a state of flux. On one hand we have golf cart manufacturers and retailers that realize lithium batteries are better for golf cart performance and longevity than lead acid batteries. On the other hand are consumers who resist the high upfront cost of lithium golf cart batteries, and consequently still rely on inferior lead-acid battery options. A November 2015 report that analyzes the golf cart battery market estimates the demand for golf cart batteries will increase roughly four percent between 2014 and 2019. The report estimates lead-acid batteries will account for roughly 79 percent of the golf cart battery market by 2019—mainly because of lithium’s upfront cost—but retailers and suppliers tell a different story. ALL IN ONE supplies lithium and AGM lead-acid batteries, and we firmly believe lithium golf cart batteries are the best option for manufacturers, retailers and consumers alike. Consumer buying trends support our position. In December 2015, the U.K. golf cart manufacturers PowaKaddy and Motocaddy announced that nearly 60 percent of their carts and electronic golf accessories sold in the UK now contained lithium batteries. Unlike the rest of Europe, which already overwhelmingly adopted lithium golf cart batteries, the U.K. has been slower to make the change. When consumers begin to understand the advantages lithium batteries provide compared to lead acid, we believe more people will demand their golf carts run on lithium power. Below is our breakdown of golf cart batteries. We compare the pros and cons of lithium and lead-acid golf cart batteries, and discuss why we feel lithium batteries are a superior choice. Carrying Capacity Equipping a lithium battery into a golf cart enables the cart to significantly increase its weight-to-performance ratio. Lithium golf cart batteries are half the size of a traditional lead-acid battery, which shaves off two-thirds of the battery weight ...

While researching lithium batteries, you’ve probably seen the terms series and parallel mentioned. We frequently get asked the question, "what’s the difference between series and parallel”, “can ALL IN ONE batteries be connected in series” and similar questions. It can be confusing if you’re new to lithium batteries or batteries in general, but hopefully we can help simplify it. Let’s start at the beginning…your battery bank. The battery bank is the result of connecting two or more batteries together for a single application (i.e. a sailboat). What does joining more than one battery together accomplish? By connecting the batteries, you either increase the voltage or amp-hour capacity, and sometimes both, ultimately allowing for more power and/or energy. The first thing you need to know is that there are two primary ways to successfully connect two or more batteries: The first is called a series connection and the second is called a parallel connection. Series connections involve connecting 2 or more batteries together to increase the voltage of the battery system, but keeps the same amp-hour rating. Keep in mind in series connections each battery needs to have the same voltage and capacity rating, or you can end up damaging the battery. To connect batteries in series, you connect the positive terminal of one battery to the negative of another until the desired voltage is achieved. When charging batteries in series, you need to utilize a charger that matches the system voltage. We recommend you charge each battery individually, with a multi-bank charger, to avoid imbalance between batteries. In the image below, there are two 12V batteries connected in series which turns this battery bank into a 24V system. You can also see that the bank still has a total capacity rating of 100 Ah. Parallel connections involve connecting 2 or more batteries together to ...

Capacity and energy of a battery or storage system The capacity of a battery or accumulator is the amount of energy stored according to specific temperature, charge and discharge current value and time of charge or discharge. Rating capacity and C-rate C-rate is used to scale the charge and discharge current of a battery. For a given capacity, C-rate is a measure that indicate at what current a battery is charged and discharged to reach its defined capacity.  A 1C (or C/1) charge loads a battery that is rated at, say, 1000 Ah at 1000 A during one hour, so at the end of the hour the battery reach a capacity of 1000 Ah; a 1C (or C/1) discharge drains the battery at that same rate. A 0.5C or (C/2) charge loads a battery that is rated at, say, 1000 Ah at 500 A so it takes two hours to charge the battery at the rating capacity of 1000 Ah; A 2C charge loads a battery that is rated at, say, 1000 Ah at 2000 A, so it takes theoretically 30 minutes to charge the battery at the rating capacity of 1000 Ah; The Ah rating is normally marked on the battery. Last example, a lead acid battery with a C10 (or C/10) rated capacity of 3000 Ah should be charge or discharge in 10 hours with a current charge or discharge of 300 A. Why is it important to know the C-rate or C-rating of a battery C-rate is an important data for a battery because for most of batteries the energy stored or available depends on the speed of the charge or discharge current. Generally, for a given capacity you will have less energy if you discharge in one hour than if you discharge in 20 hours, reversely ...

Blackouts can occur anytime. Whether it’s a natural disaster, like a hurricane, a tree limb falling on a wire or an animal coming in contact with equipment, a power outage is never convenient. Having the appropriate backup power during outages can help you worry less and give your household the power needed for your essential devices. You may be wondering, what is the best backup power solution? For decades, lead acid batteries have been the most widely adopted batteries for renewable energy systems. However, a shift is occurring as more users discover the advantages of lithium iron phosphate batteries (LiFePO4). They are now widely used to power homes and are gaining popularity as residential back up due to their many advantages. What Makes LiFePO4 an Ideal Solution for Backup Power? One shortfall of solar power systems in general is that they aren’t able to fully charge your batteries without adequate sunlight. If this happens enough, it will significantly and permanently reduce the available energy from your lead-acid battery bank and it will dramatically shorten its life. But the technology behind lithium iron phosphate battery storage has addressed this problem. LiFePO4 batteries can operate in a partial state of charge without any damage to the battery performance or life. LiFePO4 batteries also provide more usable energy. Lead acid batteries are typically over-sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Plus, you are usually cautioned to limit your use to 50% of the rated capacity, as using more will significantly reduce life. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge. And there’s more! The primary benefit of using LiFePO4 for your solar or back up system, is the total number ...

Lithium batteries have become a common part of our lives, and it’s not just in our electronic gadgets. By 2020, 55% of lithium-ion batteries sold are expected to be for the automotive industry. The number of these batteries and their use in our everyday lives makes battery safety an important consideration. Here’s what you need to know about safety and lithium batteries. Types of Lithium Batteries Before going into battery safety, it helps to answer the question, “How do batteries work? Lithium batteries operate by moving lithium ions between positive and negative electrodes. During discharge, the flow is from the negative electrode (or anode) to the positive electrode (or cathode), and vice versa when the battery is charging. The third major component of batteries are the electrolytes. The most familiar type is the rechargeable lithium-ion battery. Some of these batteries have single cells, while others have multiple connected cells. Battery safety, capacity, and usage are all impacted by how those cells are arranged, and which materials are used to make the battery components. From a safety perspective, lithium iron phosphate (LiFePO4) batteries are more stable than other types. They can withstand higher temperatures, short circuits, and overcharging without combustion. This is important for any kind of battery, but especially ones for high power applications, such as an RV battery. With that in mind, let’s look at ways of handling these batteries safely. 1: Stay Out of the Heat Batteries operate best in temperatures that are also comfortable for people, around 20°C (68°F). You’ll still have plenty of lithium power at higher temperatures, but once you get past 40°C (104°F), the electrodes may start to degrade. The exact temperature differs based on the type of battery. Lithium iron phosphate batteries can operate safely at 60°C (140°F), but even they will suffer problems after that. If ...

Here’s a quick breakdown on what distinguishes LiFePO4 from the other lithium battery solutions: Safety And Stability LiFePO4 batteries are best known for their strong safety profile, the result of extremely stable chemistry. Phosphate-based batteries offer superior thermal and chemical stability which provides an increase in safety over lithium-ion batteries made with other cathode materials. Lithium phosphate cells are incombustible, which is an important feature in the event of mishandling during charging or discharging. They can also withstand harsh conditions, be it freezing cold, scorching heat or rough terrain. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, ...

LiFePO4 Individual LiFePO4 cells have a nominal voltage of about 3.2V or 3.3V. We use multiple cells in series (usually 4) to make up a lithium iron phosphate battery pack. Using four lithium iron phosphate cells in series, gives us roughly ~12.8-14.2 volts pack when full. This is the closest thing we’re going to find to a traditional lead-acid or AGM battery. Lithium iron phosphate cells have greater cell density than lead acid, at a fraction of the weight. Lithium iron phosphate cells have less cell density than lithium ion. This makes them less volatile, safer to use, an offers almost an one-to-one replacement for AGM packs. To reach the same density as lithium-ion cells, we need to stack lithium iron phosphate cells in parallel to increase their capacity. So lithium iron phosphate battery packs with the same capacity of a lithium ion cell, will be larger, as it requires more cells in parallel to achieve the same capacity. Lithium iron phosphate cells can be used in high- temperature environments, where lithium ion cells should never be used above +60 Celsius. The typical estimated life of a Lithium iron phosphate battery is 1500-2000 charge cycles for up to 10 years. Typically a lithium iron phosphate pack will hold its charge for 350 days. lithium iron phosphate cells have four times (4x) the capacity of lead acid batteries. Lithium-ion Individual Lithium-ion cells usually have a nominal voltage of 3.6V or 3.7 volts. We use multiple cells in series (usually 3) to make up a ~12 volt lithium ion battery pack. To use lithium-ion cells for a 12v power bank, we place them 3 in series to get a 12.6 volt pack. This is the closest we can get to the nominal voltage of a sealed lead acid battery, using lithium ion ...
