No More Patchwork Battery Setups

Unlike buying a random battery from a generic marketplace and discovering the charger doesn't match or the BMS won't communicate, this complete kit is pre-vetted for component compatibility. Every piece — the 72V battery, 15A charger, battery gauge, and 12V converter — is specced to work together as one grid-independent system. No mix-and-match guesswork. Off Grid Vault curates kits we would install on our own vehicles because a battery is only as reliable as the system around it. The charger is rated for the pack. The converter handles the voltage. We already did that work.

Stable Voltage Through the Full Discharge Curve

Stable Voltage Through the Full Discharge Curve

Lead-acid batteries deliver declining voltage as they discharge, which means sluggish acceleration on the back nine and inconsistent hill climbing. This LiFePO4 system holds stable voltage from full charge to empty, giving you the same torque and responsiveness at 90% state of charge as you get at 20%. The 250A continuous discharge and 500A peak at 15 seconds mean your cart pulls hard under load — up hills, through rough terrain, or with a full passenger load. The 72V configuration also reduces current draw compared to lower-voltage setups, so your system runs cooler and more efficiently over long routes.

3,500-Cycle Life With Over-the-Air Updates

3,500-Cycle Life With Over-the-Air Updates

Most lead-acid golf cart batteries last 300 to 500 cycles before capacity drops below usable levels. This LiFePO4 battery is rated for 3,500 cycles — meaning you replace your batteries once instead of six or seven times over the same period. The integrated Bluetooth app gives you real-time visibility into voltage, temperature, and state of charge from your phone, so you are never guessing how much range remains. Over-the-air firmware updates ensure the BMS stays current as the chemistry management algorithms improve, extending field-tested performance without requiring any hardware changes. This is a built-to-survive power system, not a seasonal consumable.

Compatibility Check

This kit replaces traditional lead-acid banks in 72V golf carts and electric utility vehicles. Confirm your setup matches these conditions before ordering.

  • Your vehicle operates on a 72V electrical system
  • Battery tray accommodates a single-block lithium battery replacing multiple lead-acid units
  • Your motor controller accepts 70.4V nominal lithium input

Where This Battery Belongs

Designed for 72V platforms that need more range, more torque, and zero lead-acid maintenance.

“Replaced six lead-acid batteries in my EZ-GO with this single unit. Immediate difference — no voltage sag on hills, faster acceleration, and the Bluetooth app lets me check state of charge from the clubhouse. Off Grid Vault had everything in the box so I didn't have to source a charger or converter separately. Third season in and still performing like new.”

Frequently Asked Questions

Lead-acid batteries typically last 300–500 cycles and cost less upfront. This LiFePO4 battery delivers 3,500 cycles. Over the lifespan of one lithium battery, you would replace lead-acid six to seven times. At $2,194, the per-cycle cost drops significantly. You are paying once for a decade of performance instead of paying repeatedly for batteries that degrade faster and deliver inconsistent voltage. Finance with Affirm and the monthly cost becomes manageable against the elimination of repeated replacements.
Off Grid Vault vets every product for build quality and real-world performance before listing it. Epoch Batteries earned their place because the LiFePO4 cell chemistry and BMS design meet our standards. While the manufacturer warranty applies directly, we stand behind every offer with our 30-day performance guarantee. If the battery does not perform as specified, we make it right. That accountability is why buyers choose a specialist over a generic marketplace listing.
This kit is designed for 72V golf carts and electric utility vehicles. The single 1P22S cell configuration replaces traditional multi-battery lead-acid setups. If your cart currently runs a 72V lead-acid bank, this battery drops in as a direct replacement. For specific fitment questions — tray dimensions, cable routing, or controller compatibility — contact us for a free consultation. We will help you confirm compatibility before you buy, because guessing is how incompatible purchases happen.
At 100A max continuous charge rate, the battery can accept high current. The included 72V 15A lithium charger provides a slower, steady charge that is easier on cell longevity. Full charge time depends on your depth of discharge, but expect overnight charging from a depleted state. If you need faster turnaround, the battery supports up to 500A peak charge during regenerative braking, so downhill descents and braking put energy back into the pack quickly.
Download the companion app on iOS or Android. The battery's integrated BMS broadcasts real-time data over Bluetooth — state of charge, pack voltage, individual cell temperatures, and system health status. You see exactly what is happening without opening a compartment or connecting a multimeter. Over-the-air firmware updates push directly to the BMS, so as Epoch refines the management algorithms, your battery improves without hardware swaps. It is the same visibility you expect from a serious off-grid system, applied to your cart.
Off Grid Vault offers a 30-day performance guarantee. If the battery does not perform as specified and it is uninstalled in original packaging, you can return it for a full refund. For installed batteries, the manufacturer warranty applies and we assist with warranty claims as your point of contact. We do not vanish after the offer — that is the difference between a specialist and a marketplace listing.
