The Bolt Energy 51V 105AH Thin lithium kit replaces the entire lead-acid pack in your 48V cart with a single 5.3 kWh LiFePO4 battery — and unlike most lithium kits, everything needed for the swap comes in the box: waterproof high-speed charger, Smart state-of-charge meter, Bluetooth receiver, mounting brackets, terminal hardware, and the AC hardwire port with cover plates.

At 100.8 lbs, the pack sheds hundreds of pounds versus lead acid, which you feel immediately in hill climbing and braking. There is no watering, no terminal corrosion, and no equalization charging — top off a partial charge anytime with zero memory effect. The built-in BMS manages 250A continuous discharge with surge capability for upgraded controllers, and the Bluetooth receiver lets you check the pack from your phone.

Standard vs. Professional: the Standard kit covers a clean install on a healthy cart. The Professional kit adds a 400A heavy-duty solenoid, two 2AWG premium installation cables, a 30-amp reducer, and a lead battery removal strap — worth it on older carts or anything running a higher-amp controller.

Every Bolt Energy pack is backed by a 12-year manufacturer warranty — among the longest coverage in the industry — with US-based support from us, the people who sell it.
