The Bolt Energy USA 51.2V 105Ah square lithium battery is a high-output LiFePO4 replacement for 48V golf carts that need more range and punch than a 60Ah pack. Square-form packs fit many common tray layouts and pair with vehicle-specific Standard or Professional kits, heated options, and universal accessory kits.
Bolt Energy USA designs these packs for dealer install quality—“do it right the first time”—with Bluetooth monitoring, a smart SOC meter in kit builds, and a 12-year transferable warranty when registered promptly.
