The 48V 50Ah Lithium Rhino Conversion Kit replaces a full set of lead-acid golf cart batteries with a single 51.2V nominal lithium iron phosphate (LiFePO4) battery that weighs about 44 lb and measures 10.4 x 7.1 x 11.6 in, matching the footprint of a standard GC2 battery. It is a complete, drop-in kit for standard and stock 48V carts, and ships with everything needed to install: smart charger, LCD touchscreen, charge-port adapter, cables, mounting hardware, and safety gear.
Built for standard and stock 48V golf carts, the 50Ah Lithium Rhino kit is the entry point into lithium: one lightweight battery in place of a full set of heavy lead-acid batteries, using the footprint of a single lead-acid battery. Owners typically see 20 or more miles of range on a single charge, quicker acceleration from the lower weight, and steady power delivery as the pack discharges.
Because it is a true drop-in for stock carts, most installations are finished in an afternoon using pre-cut, labeled cables and a model-specific guide. The battery is monitored through a built-in Bluetooth module and the free Rhino app, plus an included LCD touchscreen for at-a-glance state of charge.
Why owners upgrade
-
Lighter cart: about 44 lb versus roughly 300+ lb of lead-acid, which improves acceleration and reduces strain on the drivetrain.
-
Consistent power: LiFePO4 holds voltage under load, so performance stays steady from full charge down toward empty.
-
No routine maintenance: no watering, terminal cleaning, or equalizing charges.
-
Long service life: rated for 6,000+ charge cycles.
-
Standard fit: matches a GC2 battery footprint, ideal for standard and stock carts.
Range and performance vary with terrain, tire size, passenger load, accessories, cart condition, and driving style. This kit is sized for standard and stock motor carts (roughly up to 30 mph). Lifted carts, oversized tires, high-output controllers, or heavy-duty use are better matched to a higher-capacity kit.

Fitment and Installation
Will it fit my cart?
The 50Ah kit is designed for standard and stock 48V carts from brands such as Club Car, E-Z-GO, and Yamaha. Its base matches a standard GC2 battery footprint (10.4 x 7.1 in), so it drops into the existing battery bay on most stock carts; at 11.6 in tall it sits slightly higher than a typical GC2, so confirm hold-down and seat clearance. Confirm your year, make, and model before ordering. If you are unsure, contact us and we will verify fitment for you.
How installation works
- Remove the old lead-acid batteries using the included removal strap.
- Mount the lithium battery with the included bracket and hardware.
- Connect the pre-cut, labeled cables and the 12V reducer for accessories.
- Install the LCD screen and charge-port adapter.
- Pair the Bluetooth module with the Rhino app.
Most owners complete the install in about 2 to 4 hours. Step-by-step videos are available for major cart brands, and a free 30-minute video support call is available if you get stuck.
FAQ
Will this kit fit my golf cart?
It is designed for standard and stock 48V carts from brands like Club Car, E-Z-GO, and Yamaha. The battery base matches a standard GC2 footprint (10.4 x 7.1 in), so it fits most stock battery bays; at 11.6 in tall it is slightly taller than a typical GC2, so check hold-down clearance. Confirm your year, make, and model before ordering, and contact us if you are unsure.
Does it have the same dimensions as a GC2 battery?
The length and width match a standard GC2 almost exactly (10.4 x 7.1 in), so it drops into a GC2 or 8V battery slot. It is about three-quarters of an inch taller at 11.6 in, so confirm you have the overhead and hold-down clearance for the added height.
Which carts is the 50Ah best suited for?
This is the entry-level capacity, matched to standard and stock motor carts (roughly up to 30 mph) used for golf and neighborhood driving. With 100A continuous and 150A peak output, it suits stock controllers. If you have a lifted cart, oversized tires, a high-output controller, or plan heavy-duty or long-distance use, a higher-capacity kit (65Ah, 105Ah, or larger) is a better fit.
How much range will I get on a charge?
Most owners see 20 or more miles on a full charge, which covers a full round of golf plus errands around the neighborhood. Actual range depends on terrain, tire size, passenger and cargo load, accessories, cart condition, and driving style.
Does one lithium battery really replace all my lead-acid batteries?
Yes. A single 50Ah Lithium Rhino battery replaces the entire lead-acid battery set and occupies the space of just one lead-acid battery, which frees up room and drops roughly 250 to 300 lb from the cart.
How long does installation take?
Most installs take about 2 to 4 hours. The kit includes pre-cut, labeled cables, mounting hardware, and a removal strap, and step-by-step videos are available for major cart brands. A free 30-minute video support call is available if you need a hand.
Can I use my old lead-acid charger?
No. Lead-acid chargers are not compatible with lithium and can damage the pack. Use the smart charger included in the kit. Charging with the approved charger is also a condition of the warranty.
How long does it take to charge?
A full charge takes about 6 hours at the recommended 8A charging rate. The battery accepts up to 50A, so a higher-output charger shortens that time. You can top it off after each use; there is no need to fully drain it first.
Can I leave it on the charger?
Yes. The smart charger and BMS stop the charge automatically when the pack is full, so the battery can stay connected between uses. For longer storage, see the storage question below.
How do I store the battery over winter or a long break?
Charge the pack to roughly 50 to 60 percent, then turn it off and disconnect it for storage. Avoid storing it fully discharged, and give it a top-up charge periodically. Following the storage guidance in the owner's manual keeps the warranty intact.
Can I use it in hot or cold weather?
The battery discharges in temperatures from -4°F to 131°F. Like all lithium iron phosphate batteries, charging in freezing temperatures should follow the manufacturer's cold-weather guidance; when in doubt, charge the battery where temperatures are above freezing. Contact us or Lithium Rhino support if you regularly charge in sub-freezing conditions.
Can I add more range later?
Yes. This model is parallel connectable, up to eight units, so you can add capacity if your range needs grow. It cannot be connected in series.
How do I monitor the battery?
The kit includes a built-in Bluetooth module and a free Rhino app for iOS and Android, showing live state of charge, voltage, temperature, cycle history, and fault alerts. An LCD touchscreen is also included for a quick dash-mounted readout.
What does the warranty cover?
The battery carries an 8-year limited warranty: full repair or replacement including shipping for the first 6 years, then a flat $500 deductible in years 7 and 8. Register within 120 days to keep full coverage, and charge with the approved charger. Kit components such as the charger and LCD screen carry a separate two-year full-replacement warranty. See the Warranty and Support tab for full details.
What maintenance does it need?
None of the upkeep lead-acid requires. There is no watering, no terminal cleaning, and no equalizing charges. Keep it charged, store it properly during long breaks, and use the approved charger.
