This are modules out of a 2013 Chevy Malibu eco hybrid vehicle. This is a very high power module that can discharge at a peak 50C rate for up to 10 seconds, and a continuous discharge rate of about 100 Amps. These consist of third generation Hitachi 40mm by 92mm 4.4 amp hour cells. They are enclosed in a heavy-duty all metal case for added safety.
There are wires attached that will allow the use of a BMS. We don't have the pinout of the connectors but you should be able to figure it out with an ohm meter.These are very high quality cells that tend to stay balanced without a BMS, but you would have to periodically check the individual cells with a voltmeter to be sure they are staying balanced. These are used batteries so they might have slight degradation. The voltage of each cell has been checked. They are currently resting around 3.4 volts per cell.
