Description
For longer range and heavier duty cycles, choose the Bolt Energy USA 51.2V 168Ah LiFePO4 pack. With about 8.6 kWh of usable energy on tap, this is the high-capacity option in the 48V Bolt lineup—ideal for multi-passenger carts, hilly routes, and riders who want maximum time between charges.
Configure vehicle fitment, heated or standard cells, and Standard / Professional / battery-only kits, or pick a universal accessory kit.
Key Features
- Prismatic LiFePO4 chemistry engineered for golf carts and PTVs — stable chemistry, no watering, no acid spills
- Built-in BMS with overcharge / over-discharge / temperature protection and cell balancing
- High continuous and peak discharge capability for strong acceleration and hill performance
- Bluetooth receiver + smart SOC meter (kit configurations) for state-of-charge visibility
- IP66-rated powder-coated steel enclosure designed for outdoor cart duty
- Heated pack for cold-weather charging in garages, barns, and outdoor storage. The heater runs only while the charger is connected, then shuts off once the cells are warm enough to charge

- 12-year limited transferable warranty when registered within 30 days of purchase (see warranty PDF)
- ~3,000 cycle design life / 10+ years typical service with proper charging and storage
