I have 2012-2013 Volt modules for sale for rebatterying lead EVs, custom EVs, storage. They only come stock as multiples of 48vdc and should not be taken apart, must have end plates and at least circulating coolant. This can damage the modules so I only sell complete modules with everything including the BMS which I hear has been hacked. Though I just use voltage limiting, not going over 49.2vdc/48vdc module. They are 25lbs/kwh and come in 4-5-7 kwh modules. I have access to multiple packs. They are selling for $150/kwh, $50/kwh less than taken apart modules on ebay. I'm near Tampa and best pick them up but will ship if needed. Fastenal has lower cost shipping if you pick them up at their stores if one is near you.
