Every charger we hold, with whatever its maker states about it. A charger's output is not the same number as the pack it charges, and on a cart it is not even the same number for two packs of the same voltage — a 48V flooded lead-acid bank finishes near 58V and a 48V LiFePO4 one near 54.6V, which is why a lithium conversion needs its own charger. An output is shown only where a source states it explicitly, and never inferred from a battery.
