GC2 lithium golf cart power
Upgrade your cart with a compact 48V 30Ah GC2 lithium battery built around stable LiFePO4 chemistry, smart BMS protection, IP67 durability, CANBus communication, and a GC2-style footprint for clean golf cart installations.
The Epoch 48V 30Ah GC2 battery delivers 1.54kWh of 48V deep-cycle lithium power in a familiar GC2 package. Use one module for light-duty 48V operation, or wire multiple matched batteries in parallel to build the right range for your Club Car, EZGO, Yamaha, or compatible 48V golf cart platform.
A LiFePO4 GC2 golf cart battery designed for simple, clean lithium conversions.
The Epoch 48V 30Ah GC2 lithium battery is built around the familiar golf cart battery footprint, making it a practical drop-in lithium golf cart replacement for compatible 48V systems. Instead of fabricating custom trays or forcing oversized batteries into cramped compartments, you can build a modular lithium bank around the GC2 battery dimensions your cart was already designed to hold.
Because this is a complete 48V battery module, it should replace the lead-acid bank as part of a matched lithium setup. Do not mix it with existing 6V or 8V lead-acid batteries.
Start with one 48V 30Ah GC2 module for light-duty use, or wire matched batteries in parallel for 60Ah, 90Ah, 120Ah, and up to 300Ah total capacity. This modular design lets DIY cart builders match range to real driving needs without overbuilding the system.
The built-in smart BMS helps protect the battery from overcharge, over-discharge, over-current, short circuit, and temperature extremes. Stable LiFePO4 chemistry supports long service life, consistent voltage, and maintenance-free operation.
Monitor your lithium golf cart system with the Epoch app ecosystem and CANBus communication support. Depending on your configuration, users can track key battery data such as state of charge, voltage, current, alerts, and system status.
The sealed IP67-rated case helps protect the battery from dust, rain, spray, and wet golf cart environments. It is built for outdoor use while still requiring secure mounting, protected terminals, and proper installation practices.
A technical, modular upgrade for compatible Club Car, EZGO, Yamaha, and custom carts.

Use a dedicated 48V LiFePO4 charging profile.
Pair this battery with a dedicated 48V LiFePO4 charger or properly programmed charging system. Confirm the battery bank size, cable gauge, fuse sizing, terminal torque, cart controller requirements, onboard accessories, tray fitment, and battery hold-downs before installation. For expanded banks, use matched Epoch 48V 30Ah GC2 batteries of the same model, age, capacity, and state of charge.
Lighter weight, stable power, faster charging, and zero watering.
LiFePO4 golf cart batteries provide a flatter voltage curve than lead-acid batteries, helping maintain more consistent acceleration and torque through the discharge cycle. They also eliminate watering, acid maintenance, corrosion cleanup, and the heavy lifting associated with traditional lead-acid golf cart battery banks.
Common questions about GC2 fitment, parallel expansion, charging, app monitoring, and lithium conversion.
GC2 is a common golf cart battery case size used by many 6V and 8V lead-acid golf cart batteries. The Epoch 48V 30Ah GC2 lithium battery is engineered in a GC2-style footprint, so it can fit many factory golf cart battery trays without custom fabrication. Always confirm your tray dimensions, cable clearance, hold-downs, charger, and controller requirements before installation.
A single 48V 30Ah battery can power a compatible 48V golf cart for light, short-distance use. For typical 18-hole use, neighborhood driving, hills, passenger loads, or upgraded controllers, many owners install two, three, or four batteries in parallel to create 60Ah, 90Ah, or 120Ah of total capacity.
Yes. This battery supports parallel expansion only, with up to 10 batteries in parallel for a maximum 48V 300Ah battery bank. Series wiring is not supported, so do not connect these batteries in series to increase voltage.
Yes. Use a dedicated 48V LiFePO4-compatible charger. The battery has a 57.6V maximum charge voltage and a 30A maximum charge current. Avoid old lead-acid chargers with desulfation or equalization modes unless they can be programmed to safe LiFePO4 settings.
No. Do not mix lithium and lead-acid batteries in the same battery bank. They use different voltage curves, charging profiles, and internal resistance characteristics. Remove the existing lead-acid bank and build a matched 48V lithium system using batteries of the same model, age, capacity, and state of charge.
The product page lists iOS and Android app support, and the battery platform also uses CANBus communication for system telemetry. Follow Epoch's setup instructions for the compatible app, CANBus ports, battery gauge, and any required communication accessories for your specific configuration.
Yes. The battery is rated IP67, meaning it is designed to be dustproof and water-resistant for demanding golf cart and outdoor environments. It should still be installed securely, with proper terminal protection and without creating a location where water can remain trapped around the battery.
