Choosing the Chemistry of Your Lithium-Ion Battery

Lithium batteries are very popular in all kinds of projects, especially special projects. There are several options on the market, but sometimes there is a need for a personalized lithium-ion battery. Building a battery from scratch can be somewhat premature, especially given the sheer number of tools it takes to build the battery.

However, there are some kits that can come in really handy if you're ready to try at all. There are manufacturers that make custom lithium-ion batteries according to the specifications you set. You can also get 18650 lithium ion battery online via

Making a Choice

The choice of battery chemicals is very important. There are several types of batteries that you can use for your project. They include:

  • Li-Ion (Lithium-Ion)
  • LiFePO4 (lithium ion phosphate)
  • Li-po (lithium polymer)

The most common battery is Li-ion. This means you can find them in different strains, even though all of their characteristics are similar. They are usually inexpensive, safe if you don't abuse them, and have high energy density. Most of the electric vehicle manufacturers use this ion battery.

The LiFePO4 option is not energy dense like the lithium ion. This means they are heavier and bigger. Most of the batteries in this category have a much lower discharge rate. This option is slightly more expensive and usually safer. Their life cycle is also quite long.

Li-Po batteries are common with R / C drones. Your level of performance is quite high. They can also be dangerous, especially if handled with care. You should only use this option when you need to run a high-performance project.
