  • Why Buy From Us
  • The Epoch 36V 100Ah Big Box Series kit is a complete lithium conversion for compatible 36V golf carts. One 38.4V, 100Ah, 3.84kWh LiFePO4 battery replaces a multi-battery lead-acid bank, and the kit includes the onboard charger, dash gauge, remote switch, 12V converter, charge port plug and mounting hardware matched to your cart. Choose EZGO TXT, Club Car DS, or Other for Yamaha and other compatible 36V carts.

    The 81 lb battery delivers 200A continuous and 700A peak for up to 2 seconds, accepts regenerative braking current, and needs no watering or acid service. Built-in Bluetooth, an advanced BMS and an IP67 stainless-steel enclosure come standard, backed by an 11-year limited manufacturer warranty and a 3,500+ cycle rating. Epoch estimates roughly 30 to 40 miles per charge for many standard 36V carts.

    Key Features

    • Complete conversion kit: Battery, 36V 15A onboard lithium charger, extension cord, gauge, remote switch, 12V converter, charge port plug and cart-specific mounting hardware in one kit.
    • One battery instead of a bank: A single 81 lb LiFePO4 battery replaces several heavy lead-acid batteries with fewer corrosion-prone connections.
    • 200A continuous, 700A peak: 300A for up to 15 seconds and 700A for up to 2 seconds for acceleration, hills and heavier loads.
    • Regen-ready charging: Accepts 100A continuous charge and up to 300A for 15 seconds of regenerative braking; the included charger fills it from empty in about 7 hours.
    • Gauge, app and OTA updates: The dash gauge and Epoch Li-Ion app show state of charge, voltage, current, temperature and warnings, with over-the-air firmware updates.
    • IP67 and advanced BMS: Dust-tight and protected against temporary immersion to 1 m for 30 minutes, with full BMS protection, cell balancing and a low-charge warning.
    • 12V accessory power: The fused 25A step-down converter with key-on wire runs 12V lights, audio and accessories from the 36V battery.
    • 3,500+ cycles, no watering: Long LiFePO4 cycle life with no water refills or acid service.

  • Epoch Batteries Limited Warranty

    Warranty Period
    11-year limited manufacturer warranty covering qualifying defects in materials and workmanship under normal use, subject to Epoch Batteries' warranty terms
    Register within 90 days of purchase for full coverage

    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.
