The Epoch 48V 30Ah GC2 golf cart battery (model GC2-R-B4830) is a complete 51.2V LiFePO4 module with 1.54kWh of storage in a GC2-style footprint. It is designed for 48V golf cart lithium conversions, letting you build a modular bank in the battery tray your cart already has.
Use one module for light, short-distance driving, or connect matched modules in parallel for 60Ah, 90Ah, 120Ah and up to 300Ah. A smart BMS, CANBus communication, an IP67 case, UL2271 pack certification, 4,000+ cycle life and an 11-year manufacturer warranty round it out.

Epoch Batteries Limited Warranty
Warranty Period
11-year manufacturer warranty
Epoch Batteries-branded products are covered against qualifying defects in materials and workmanship for the applicable warranty period, subject to Epoch's model-specific remedy schedule and the terms of its warranty policy. Epoch-branded chargers carry a 2-year limited warranty and accessories (such as fuel gauges and voltage reducers) a 1-year limited warranty, from the original purchase date.
Registration
Register your battery with Epoch within 90 days of purchase for full warranty coverage. If it is not registered within that time, the warranty period begins from the battery's original manufacturing date. Proof of ownership is required for any claim, and coverage is non-transferable and applies only to the original purchaser.
Remedy
After inspection and testing, Epoch will provide the applicable remedy for a qualifying manufacturing defect: an approved repair, a replacement, or a comparable-product offer according to the model's schedule. Typical repair turnaround is 3–10 business days once the product is received.
Exclusions
Coverage may be denied when a failure is caused by misuse, improper handling, installation or storage, or use outside the product's specifications. Examples include an unsecured battery; loose, corroded or improperly connected terminals; series or parallel connections beyond the manufacturer's recommendations; reverse polarity or short circuits; impact, fire or water submersion; storage above 140°F or below -40°F; prolonged storage fully discharged or batteries left uncharged for more than three months; poor crimps, undersized cables or damaged wiring; opened, modified or tampered products; and use in applications the battery was not designed for, including repeated engine starting on non-cranking models.
Obtaining Warranty Service
Start a claim through the Epoch Batteries Warranty Portal with your model and serial number, proof of purchase, a description of the issue and supporting photos or videos. If approved, Epoch provides an RMA number and packing instructions. Do not ship a product without a valid RMA. The customer arranges and pays for shipment to Epoch, packaged in compliance with lithium battery shipping rules. Epoch Batteries can be reached at 1-888-501-1846 or support@epochbatteries.com.
