Compatible batteries
Epoch's own charger and Epoch's own pack. Bank two of this unit is 36 V at 10 A and Epoch state it takes a "Compatible 36V LiFePO4 battery only" — this pack is 36 V LiFePO4. It names a class and not this model, so the row establishes that the pack is inside the description bank two gives, not that Epoch tested this pairing.
