Battle Born Battery: This is a high-quality manufacturer. If you don't have the time, tools, or desire to build a battery yourself, then check out Battle Born. Use coupon code "DAVIDPOZ" for free shipping.

But, if you want more fun and the satisfaction of making things yourself, then you are like me. I want to DIY my own battery. Luckily, Battery Hookup recently started selling their own branded cells. These things are LiFePO4 cells, nominal 3.2 volts. They are 32700 (32650) cell size.
Anything from Battery Hookup can be purchased using my coupon code "DAVIDPOZ" for 10% off.

I have no affiliate with Keith, from 18650'ed. He sells accessories for builds. I purchased my K-weld spot welder from him, along with the Kapton tape, and nickel strip.
Case, Empty. I purchased mine through Aliexpress. However, you may be able to find it locally. Keith, from 18650'ed, sometimes has some empty cases in stock. I suggest checking with him first.
