BigBattery

A direct-selling lithium pack maker whose golf-cart line runs 36 V, 48 V and 72 V, sold as modules and as multi-module kits. They publish twenty-four specification rows per pack — including the BMS cutoff range, the cell configuration and what the pack communicates over — which is four times what most makers here publish. What they do NOT publish is a fitment table: their golf-cart page names four cart brands and no model, year or controller.
