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.

In this article, we will discuss how to attach a BMS to a lithium-ion battery. We will also go over each connection and explain what they all mean so your BMS install can be flawless.
If you have an older battery system then you may be wondering how to replace lead acid/AGM with lithium. Lithium-ion batteries are much more weight, volume, and cost-effective compared to lead acid and AGM batteries. So, it’s only natural to wonder if it’s possible to upgrade from the older lead acid and AGM batteries to newer, more efficient lithium-ion batteries.
If you are a newcomer to the field of battery building, it can be challenging to find the best spot welders for battery packs. This is compounded by the fact that different batteries for different applications have varying needs in terms of what type of spot welder is used for the job.
Learning how to spot weld battery packs is a crucial step if you plan on building or designing portable electronics. Sure, you could always buy pre-built battery packs for your projects but they will never be as low cost as doing it yourself. Also, without knowing how to spot weld battery packs, you are left to the mercy of the quality, shape, size, and availability of pre-build batteries.
If you built a lithium ion battery and its capacity is not what you expect, then you more than likely have a balance issue. While it's true that cells connected in parallel will find their own natural balance, the same is not true for cells wired in series. It's important to know how to balance a lithium battery pack.
Buck converter or boost converter, which is best? When you have to change one voltage to another, this question can come to mind. Many of the devices that we rely on every day have some sort of boost or buck converter circuit built into them. This makes sense if you think about it. Things like hard drives, mp3 players, video recorders, laptops, and many other devices require voltages that are outside of the natural range of a lithium-ion battery pack.
While it is true that batteries come in many different sizes, shapes, voltages, and chemistries, lithium-ion batteries are by far the most common type of battery cell that you will come into contact with. It is important to consider, however, that not all lithium-ion cells are the same. In fact, lithium-ion cells within the same sub-chemistry can have substantially different properties.
When working with lithium-ion batteries, there are many types that you will come across. The overwhelming majority, however, will be either 18650 or 21700 cells. So, you may be wondering which cell type is best for your application.
Are you wondering how to plan a portable power pack? It’s actually not all that hard of a thing to do, there are just some key aspects and basic ground rules that need to be considered first.
