Choosing the correct lithium battery cells is a crucial step in designing an efficient and reliable battery system for your project. With a wide array of options available, it&#;s essential to carefully evaluate various technical factors to ensure optimal performance, safety, and longevity. In this guide, we&#;ll break down the key considerations for selecting lithium battery cells, offering clear guidance and practical examples to help you make informed decisions.

Capacity is the measure of how much electrical charge a battery cell can store, typically measured in ampere-hours (Ah) or milliampere-hours (mAh). To determine the appropriate capacity for your project, consider your energy requirements and runtime expectations.
Energy density represents the amount of energy stored per unit volume or weight. While higher energy density cells can store more energy in a smaller or lighter package, they may come with a higher cost.
Lithium battery cells come in various voltages&#;typically 3.2V, 3.6V, or 3.7V&#;depending on the specific lithium chemistry. To select the right voltage, you need to consider your project&#;s voltage requirements and the configuration of your battery system.
Series Configuration: Increases the total voltage by connecting cells in series.
Parallel Configuration: Increases capacity by connecting cells in parallel.
Different lithium battery chemistries offer varying performance characteristics, cycle life, and safety features. Common chemistries include:
When choosing the chemistry, consider factors like energy density, discharge rate, temperature range, and safety. If you&#;re debating between lithium-ion and lithium-polymer batteries, our article on the benefits of lithium-Ion batteries over lithium-polymer batteries provides an in-depth comparison that might help clarify your decision.
The discharge rate indicates how much current a battery can provide continuously or in bursts. It&#;s vital to ensure that the battery cells can handle your project&#;s current demands without sacrificing performance or longevity.
Cycle life refers to the number of charge-discharge cycles a battery can undergo before its capacity significantly diminishes. If your project involves frequent use and requires a long lifespan, opt for cells with a high cycle life.
Lithium battery performance can vary significantly with changes in temperature. High temperatures can accelerate degradation, while low temperatures can reduce the available capacity. If your project operates in extreme conditions, consider cells designed for high or low-temperature performance, and explore temperature management solutions like passive or active cooling systems.

Safety should always be a top priority when selecting battery cells. Look for cells equipped with built-in safety features, such as:
Additionally, ensure that the cells comply with relevant safety certifications like UL or IEC to minimize the risk of accidents.
Consider the physical size and form factor of the battery cells to ensure they fit seamlessly into your project&#;s battery pack or system. Measure the available space and any weight restrictions before making your choice.
Choosing a reputable supplier is essential for sourcing high-quality lithium battery cells. Research suppliers by looking at their track record, customer reviews, and their ability to provide technical support and after-sales service.
If your project requires a unique battery solution, custom battery pack design might be the answer. When designing a custom pack, it&#;s crucial to consider factors such as cell selection, thermal management, and physical layout. Prototyping plays a vital role in this process, allowing for the testing and refinement of the design before moving to full-scale production.

Lithium batteries are powerful, long-lasting options for personal and professional use. We use these battery packs for golf carts, forklifts, RVs, and much more. However, there may come a time when you need to put temporarily unused batteries in storage. Doing so the wrong way, however, could result in damage to the batteries and a reduction in performance when you go to use them again.
BigBattery is here with a guide to safely storing lithium batteries and ensuring you have the proper physical and mechanical conditions to maximize the longevity of your batteries. Fortunately, lithium battery packs are highly durable, and you may only need to make a few changes for adequate long-term storage. Read on to become a battery-storage pro!
One of the first questions to address with battery storage is whether you need to disconnect the battery from its larger power system. For example, you may think you can put your golf cart into storage, and that effectively puts the battery away with it. However, that&#;s not the best idea.
Even when you turn off the electrical components of your golf cart, camper van, or other vehicle, the battery still self-drains at a rate inherent to its chemistry, and leaving it connected will cause it to drain faster, potentially shortening its lifespan. So for the sake of your lithium battery pack and what you connect it to, we recommend separating the two when keeping them in extended storage, typically 3 &#; 6 months or longer.
When you plan to store your battery pack for a long time, be sure to charge the battery to around 60 &#; 80 percent capacity. Again, your batteries will self-discharge over time, so keeping a written record of when you put them in storage or most recently charged them can benefit you in the long run.
Additionally, we suggest charging your battery pack roughly every three months. While many modern lithium battery chargers have a fail-safe to prevent overcharging, we advise against leaving your battery on a charger for any extended charging period.
When figuring out how to store lithium batteries, you should consider several factors. Fortunately, it&#;s usually not too difficult to find adequate conditions in which to store these packs and keep them safe from damage. Here are just some of the things you should pay close attention to:
Unlike many older lead-acid batteries, lithium battery packs have a much greater tolerance for extreme temperatures. However, that doesn&#;t mean you shouldn&#;t be careful. The ideal temperature range for a lithium battery pack in storage is between 35 to 90 degrees Fahrenheit. No matter where the ambient temperature of your storage area falls within that range, you should try to keep that temperature as consistent as possible.
Lithium batteries are not likely to suffer any noticeable damage unless you store them at consistently extreme temperatures such as under 20 degrees or over 100 degrees Fahrenheit. Nevertheless, keeping them at a comfortable temperature is ideal for battery longevity. Being stored outside the optimal temperature range for long periods may cause them to self-discharge faster and require more maintenance while in storage.
You don&#;t need to keep your lithium batteries in pitch blackness, but limiting light as much as possible is generally a good idea. Exposure to light, especially natural sunlight, may cause cosmetic damage and temperature changes that can negatively impact the inner workings of your batteries. So try to reduce exposure to harsh or overly direct sunlight and keep your batteries in a cooler, covered area to reduce the risk of any long term issues.
It&#;s usually not a good idea to mix batteries with water, and that same idea applies when you want to keep batteries in storage. While lithium batteries have self-contained structures that typically do a good job of keeping out excess moisture, you should always try to keep them in a dryer area with little to no humidity. If you live in an area with high humidity, we suggest keeping a dehumidifier or a desiccant bucket nearby. This will help keep some of the moisture from affecting your battery pack.
