Battery 42 LI-ion battery modules (each containing 8 internal cells) recycled from a Nissan Leaf.
A 2012 Nissan leaf had 48 of these modules, so the trailer has 87.5% of that capacity.
The Leaf was rated at 24 kwh (kilowatt hours) of energy storage, so that trailer has approximately 21 kwh (actual performance will probably be a bit less).
Each module is 8 volts fully charged (Capacity: 41Ah Maximum Continuous Charge & Discharge Current: 130A)
6 batteries are connected in parallel to create one bank. That's still 8 volts Connections are made with bolted copper bus strips, 1.5 wide, 1/4" thick
7 of those packs are connected in series. That's ~ 48 volts (56, sure, but this system runs at 48 VDC)
