Epoch 48V 150Ah Golf Cart Battery Complete Kit – Lithium (LiFePO4)
The Epoch 48V 150Ah golf cart battery kit is a complete lithium conversion for compatible 48V carts. One 51.2 V, 7.68 kWh LiFePO4 battery replaces a full bank of 8V or 12V lead-acid batteries, and the kit includes a 22A charger, dash gauge, switch, 12V converter, charge port plug and mounting brackets. Choose EZGO TXT for an EZGO TXT cart, or Other for another compatible 48V cart. Explore more options in our lithium battery collection.
Key features
- Complete kit: battery, 48V 22A onboard lithium charger with a 10 ft extension cord, digital Bluetooth gauge, 6 ft remote on/off switch with harness, fused 48V to 12V converter (25 A), cart-specific charge port plug and mounting brackets.
- High capacity: 51.2 V, 150 Ah, 7.68 kWh (7,680 Wh nominal) in one battery.
- Strong output: 300 A continuous discharge, 500 A for up to 15 seconds and 1,000 A for up to 2 seconds, for acceleration, hills and upgraded controllers.
- Regen-ready: accepts 150 A continuous charge and up to 500 A for 15 seconds of regenerative braking.
- Monitoring: dash-mounted digital gauge and the free Epoch Li-Ion app (iOS and Android) show state of charge, voltage, current, temperature, battery health and warnings. Firmware updates over the air.
- IP67 enclosure: stainless-steel case, dust-tight and protected against temporary immersion to 1 m for 30 minutes.
- Long service life: 4,000+ cycles, no watering or acid service, 11-year limited warranty.
- Expandable: up to 2 batteries in parallel (300 Ah, 15.36 kWh).
What's in the kit
- 48V 150Ah LiFePO4 battery (51.2 V, 7.68 kWh)
- 48V 22A onboard lithium charger with a 10 ft heavy-duty extension cord
- Digital Bluetooth battery gauge for the dash
- 6 ft remote on/off power switch with wiring harness (a 13 ft harness is available for stretched carts)
- Fused 48V to 12V step-down converter, 25 A, with key-on wire (for 12V lights, light bars, radios and USB outlets)
- Cart-specific charge port plug, which replaces the factory lead-acid receptacle
- Cart-specific mounting brackets (EZGO TXT or Other)
A main fuse or DC-rated circuit breaker for the battery cables is not included. Install one as close as practical to the battery positive terminal, and make sure the cables and lugs are sized for your installation.
Fitment and compatibility
Choose the EZGO TXT configuration for an EZGO TXT cart, as its brackets and charge port plug are matched to the cart. Choose Other for another compatible 48V golf cart, neighborhood electric vehicle or utility vehicle, and confirm tray space for the 19.84 × 15.35 × 9.84 in case, mounting, cable routing and charge-port wiring. The controller's current settings must stay within 300 A continuous, 500 A for up to 15 seconds and 1,000 A for up to 2 seconds. Some Club Car carts with an On-Board Computer (OBC) may need an OBC bypass so the included lithium charger can charge the battery.
Performance and range
One 150 Ah battery supports demanding carts and upgraded controllers and motors whose current demand fits the battery ratings. Range depends on terrain, passenger weight, tire size, lift kits, controller tuning, motor condition, speed and accessory load. Use the gauge and the app to track your own usage and learn your cart's range.
Charging
The included 22A charger is powered through the cart's charge port and charges the battery from empty in about 7 hours (an estimate). If the charger stays connected, it restarts below about 95% state of charge. Do not use a lead-acid charger, as it will not properly charge or balance the battery, and never use equalization, desulfation or repair modes.
Cold-weather and water protection
This battery has no internal heater: the BMS blocks charging outside 0°C to 55°C (32°F to 131°F), so let a cold battery warm above freezing before charging. It can discharge from -10°C to 55°C (14°F to 131°F). The IP67 enclosure is dust-tight and protected against temporary immersion, but it is not rated for water jets or pressure washing.

Installation notes
Before installing, confirm that your cart is a compatible 48V platform and check the battery bay, terminal clearance, cable size, overcurrent protection and the controller's current settings. Size conductors and overcurrent protection to the 300 A continuous rating. At 135 lb (61 kg), the battery is heavy, so use suitable lifting equipment and secure it with the supplied brackets. Replacing the factory charge receptacle with the supplied plug is required for safety. Before wiring the 12V converter, turn the battery off and disconnect the charger, and confirm the two black converter wires (input negative and output negative) before connecting them, since reversing them can damage the converter or the accessories. If any cell falls below 2.2 V or the pack falls to about 38 V, the battery powers down: switch it on, then charge it immediately.
