Latest news, guides, and articles about battery storage. We write about lithium-ion, LiFePO4, and more.
The principal benefit of lithium ion batteries is their ability to store large amounts of energy in a relatively small space. Lithium ion batteries have the added benefit of having an extremely high depth of discharge compared to lead acid batteries. This is why lithium ion batteries are generally the only type of battery to use for energy storage.
For energy storage applications, nominal voltages of 12, 24, and 48 are used. This generally means that the batteries in the energy storage system will generally be in either a 3S (4S for LFP), 7S, or 13S series configuration. Energy storage batteries generally have an amp hour rating of 100 Ah or more, but smaller energy storage batteries can be made.
Articles in this category will revolve around long term energy storage, electrical preparation techniques, high capacity battery packs, and various series and parallel battery configurations.

When buying new cells for a DIY powerwall or after you finish building a new battery pack, being able to test capacity is crucial in confirming your build quality. Knowing the capacity to ensure you are getting what you paid for is also helpful. Having a good capacity tester is crucial and we go over them here.
Understanding nominal voltage and its importance when building, using, or buying a battery pack is crucial. This figure helps to interpret the voltage range of a battery pack or cell into a single number, which helps to simplify things. We go over nominal voltage in detail in this article and also touch on nominal voltage by common cell chemistries.
When building a battery pack choosing the best cell format often leads to cylindrical vs pouch cells. Each has its pros and cons to assess before choosing which will be used. One of the biggest questions is what are the main drawbacks of pouch-based LiPo cells. We go over that here!
When building a battery pack safety is almost always the first thing to address. In this article, we go over the safety battery cell by chemistry and the considerations to decide which is right for your build. There are some trade-offs when it comes to making this decision so knowing all the factors makes the choice much easier.
Sizing a portable power station is important to make sure the one you purchase meets your needs. There are a few things to consider to make sure you pick right the first time. Follow along with our guide here to help make your power station purchase a success.
There are many different ways to test a battery pack's health. I often get asked the question of which one is the best or which is most accurate. Well, simply the most accurate can be defined by one type of testing. Where the most accurate encompasses a few different tests to preform.
People often ask "can I charge a lithium battery with a car battery charger". Questions like this to some are common sense as to the answer being NO! We go over why you cant just use any old charger to charge a lithium battery in this article.
When working with lithium batteries you come across two main types of BMS common port is the most common of the two. This is mainly due to its ease of use and less complexity. Its separate port has some limitations but these don't make them any worse than their common port counterpart.
In the case of large battery banks with multiple batteries or running two batteries in parallel for an ebike, making sure all the packs stay in balance is crucial. Firstly you have to make sure they are all connected properly to avoid any current inrush and after the system is assembled regular monitoring is good to do to ensure overall system health.
