BigBattery's own FAQ: "What charger works with the 72V RAPTOR 2? This 72V 15A charger is designed for 72V LiFePO4 systems including RAPTOR 2 setups. ... which matches the RAPTOR 2's 85.2 to 87.6V charging range." That range matches the battery's working voltage range, from its own spec sheet -- an independent cross-check between two different BigBattery product pages.
Compatible carts
Sources do not establish: Which Club Car model. BigBattery name Club Car as a brand their pack works with and name no specific model, year, trim or controller rating in that statement — so this is not a claim about this model in particular. Also not established: this cart's system voltage against the pack's, the battery compartment it would need to fit, the continuous and peak discharge its controller demands against what this pack's BMS delivers, and whether this model's charger is safe for this chemistry — none of it is addressed by a brand-list statement. The same applies to E-Z-GO and ICON Electric Vehicles.
