Drop-In 72V LiFePO4 Conversion for Your Golf Cart

This field-tested LiMax Series kit replaces your lead-acid bank with a single 70.4V 105Ah LiFePO4 unit — no complex multi-battery wiring required. You get stable voltage through the full discharge curve, meaning consistent torque and acceleration without the sag that kills lead-acid performance. The grid-independent design includes a 72V 15A charger, battery gauge, 12V converter, and Bluetooth monitoring so you track voltage, temperature, and state of charge in real time. Built-to-survive chemistry delivers 250A continuous and 1000A peak discharge — enough for hills, loads, and rough terrain without breaking a sweat.

No More Lead-Acid Guesswork

No More Lead-Acid Guesswork

Lead-acid banks require constant watering, corrode terminals, and voltage-sag under load — killing your torque on hills and shortening battery life to a fraction of rated capacity. This LiMax Series kit eliminates that cycle. Off Grid Vault pre-vets every component in this kit so the charger, converter, and battery speak the same language. No mixing brands and hoping it works. The 72V 15A charger and 12V converter are matched to the battery's charge profile. You bolt it in, connect it, and drive — with stable 70.4V output from 100% to near-zero state of charge.

Power That Holds Up Under Load

Power That Holds Up Under Load

With 250A max continuous discharge and 1,000A peak at 2 seconds, this battery delivers the surge current your motor demands on steep inclines and from a dead stop. The 1P22S cell configuration maintains balanced voltage across all cells, while 500A peak charge regen captures energy on downhill braking without overheating. That translates to noticeable torque improvement over lead-acid — not just on paper, but on every hill and every acceleration from a standstill. The 72V architecture reduces current draw compared to lower-voltage systems, meaning cooler operation and less stress on your motor and controller.

Monitor Everything From Your Phone

Monitor Everything From Your Phone

The integrated Bluetooth app gives you real-time visibility into state of charge, voltage, temperature, and cell-level health — iOS and Android. Over-the-air firmware updates mean the battery improves after purchase, not just on day one. At 3,500 cycles, this built-to-survive LiFePO4 unit outlasts lead-acid by roughly 7x under the same usage pattern. For a golf cart running daily, that is years of maintenance-free operation with no watering, no terminal cleaning, and no seasonal replacement. The lighter weight compared to a full lead-acid bank also improves handling and reduces overall vehicle wear.

Compatibility Check

Verify these conditions before ordering to ensure a straightforward installation.

  • Vehicle operates on a 72V (72V nominal) electrical drive system
  • Battery tray or compartment fits a single-unit drop-in replacement footprint
  • 12V accessory loads are compatible with the included 12V converter output

Where This Battery Belongs

From daily course runs to property patrols, this kit handles the work that lead-acid can't sustain.

“Replaced six lead-acid batteries in my EZ-GO with this single unit. Install took 45 minutes. The difference on hills is night and day — no more sag, and the Bluetooth app lets me check everything from the clubhouse. Wish I had done this years ago.”

Frequently Asked Questions

Lead-acid banks for 72V carts typically need 6-8 batteries replaced every 1-2 years. At 3,500 cycles, this LiFePO4 unit lasts significantly longer under the same usage. Factor in zero maintenance costs — no distilled water, no terminal cleaning supplies, no corrosion damage to your cart's wiring. The upfront investment pays for itself over the battery's lifespan through replacement cycles avoided and reduced vehicle maintenance.
This kit is designed for 72V golf carts and electric utility vehicles. The included 12V converter handles your accessories — lights, horn, radio — so you do not need a separate 12V battery. For compatibility specifics beyond 72V configuration, contact us with your cart make and model. Our team can confirm fitment before you purchase.
Off Grid Vault offers a 30-day performance guarantee. If the battery does not perform as specified when you receive it — uninstalled and in original packaging — you can return it for a full refund. For installed systems, warranty claims are handled directly through us as an authorized dealer, so you deal with a real person, not a ticket queue.
Since this is a single-unit replacement for a multi-battery lead-acid bank, most installations complete in under an hour. The kit includes the charger, gauge, and 12V converter — everything needed for the conversion. No complex wiring harnesses to build. If you can remove your old batteries and connect a few cables, you can install this system.
The 70.4V 105Ah LiFePO4 cell delivers usable capacity that lead-acid cannot match — lead-acid batteries should not be discharged below 50% for longevity, effectively halving your rated capacity. With LiFePO4, you access far more of the rated 105Ah. Combined with the weight reduction and stable voltage under load, most users report noticeably longer range per charge and stronger performance on inclines.
The included 72V 15A lithium charger is designed for standard household outlets. Plug it in, connect to the battery, and it handles the full charge cycle. Because the charger is matched to the LiFePO4 charge profile by Off Grid Vault, you do not need to worry about incorrect voltage settings or overcharge risk.
