48 volt server battery available from Battery Hookup. This video is kinda long because I start with tearing the battery down. Then re-building it with a new BMS from Daly. Charging to 4.2 volts per cell. Then I do a capacity test at about a 0.2C rate. Finally I use the battery in a real-world test. Guess what, I can weld with it! Wow.
The battery is originally made for server racks. It is capable of 100 amps discharge! Huge for such a small package. The steel case and insulating liner makes this a very safe enclosure.
Battery Hookup is going to sell the battery and BMS used in this video. Use coupon code "davidpoz" for 10% off.

I think this battery is better suited to smaller projects. Maybe an electric go-cart, E-bike, portable power station, etc. Yes, it can also be used in powerwalls.
