These battery modules came from residential systems and feature Samsung SDI 94 amp-hour NMC cells. There are qty 5 packs of 6 cells in series, for a total of 30 cells in series. That's 111 volts nominal and 10.4 kilowatt-hours of capacity. And each cell is capable of 300 amps (3C) discharge, although these are limited by qty 2 125-amp fuses per pack.
The cells are laser welded with aluminum bus bars. We've already configured one pack to a 14S2P configuration (effectively eliminating two cells) to power an inverter running our analyzers. The bus bars have connectors that make connecting a BMS a breeze.
This just so happens to match perfectly with a popular EV conversion kit. If you have a Volkswagen Type 2 bus, these are an excellent and inexpensive battery.
These will need to be shipped freight and do not qualify for free shipping.
