Golf Cart Lithium Conversion Kits

Why Switch to a Lithium Conversion Kit?

Traditional lead-acid and gel battery banks get the job done, but they come with trade-offs: regular watering, slow charging, gradual performance drop-off as the pack drains, and a service life of roughly 3 to 5 years before you're buying again. Lithium changes most of that equation. LiFePO4 batteries maintain steady voltage throughout the discharge cycle, meaning your cart doesn't slow down as the charge drops. They charge significantly faster, weigh a fraction of what a comparable lead-acid bank weighs, and are rated for 5,000 to 6,000-plus charge cycles — which translates to a decade or more of reliable use depending on how often you ride.

The conversion process itself has also gotten much more accessible. Both brands we carry offer kits that are designed to drop into your existing battery tray, and Lithium Rhino's kits include every component — hardware, wiring, charger, display — in one package. If you're comfortable doing basic work under the seat of a golf cart, this is a manageable DIY project.

Ionic Lithium — Scalable GC2 Bundles with Bluetooth

Ionic Lithium (manufactured by LithiumHub) takes a modular approach. Their GC2-format LiFePO4 batteries are designed to be connected in parallel, so you start with one battery and add more as needed — up to four. Each battery in the lineup carries an 11-year warranty and comes equipped with Bluetooth connectivity. Open the Ionic app on your phone and you'll see real-time charge level, voltage, current, and estimated time to full charge. There's no guessing how much range you have left.

We carry Ionic Lithium bundles for both 36V and 48V systems:

• Single (27Ah) — A starter option for light use or for golfers who want to try the technology before committing to a full conversion. A single 36V unit delivers approximately 8 to 10 miles of range; the 48V version runs 3 to 6 miles on a charge.
• Double (54Ah) — Two batteries wired in parallel. Range roughly doubles from the single, making this a solid choice for 9-hole rounds or neighborhood and community use.
• Triple (81Ah) — Three batteries in parallel. The sweet spot for most golfers completing a full 18-hole round and for hilly terrain where power demand is higher.
• Quadruple (108Ah) — Four batteries in parallel. Maximum range from Ionic's GC2 platform, ideal for heavy use, larger carts with rear seats, or anyone who simply doesn't want to think about charging between outings.

One thing worth knowing about the Ionic system: each individual battery includes cold-weather protection that prevents charging below approximately 24°F. This is a safety feature that protects lithium cells, not a flaw — but if you're in a cold climate and charging outdoors in winter, it's worth being aware of. On the performance side, Ionic batteries support 99% depth of discharge, and their advanced BMS handles cell balancing, over-voltage and under-voltage protection, and short-circuit protection automatically.

Lithium Rhino — Complete All-in-One Kits, 36V Through 76V

Lithium Rhino sells complete conversion kits rather than individual batteries. Each kit ships in a reinforced wooden box and includes the battery, a fast 25-amp smart charger, an LCD touchscreen with mounting bracket, a 40-amp 12V reducer (for carts with 12V accessories), all necessary wiring, mounting hardware, and a drill bit. There's also a 30-minute installation support call included with every kit, plus safety gear for removing your old lead-acid batteries. For first-time converters, it's about as turnkey as a DIY project gets.

Lithium Rhino kits are rated at 6,000-plus charge cycles and carry an 8-year warranty. Their Bluetooth app offers real-time monitoring and also includes an anti-theft feature that lets you lock the battery remotely to prevent the cart from operating. The 25-amp charger replenishes a fully discharged pack in roughly 4 hours.

The range across the Lithium Rhino lineup covers most carts on the road today:

• 36V 65Ah — Entry-level 36V option, approximately 25 miles of range. A good starting point for older 36V carts used primarily on flat terrain.
• 36V 105Ah — The higher-capacity 36V option, rated for 40 to 50 miles per charge. Better suited for carts with rear seats, hilly courses, or heavy daily use.
• 48V 50Ah — The lightest 48V kit in the lineup, rated for 20 to 25 miles. A practical upgrade for casual riders replacing a worn-out lead-acid bank.
• 48V 65Ah — A step up in capacity, delivering 27-plus miles. Adds useful reserve without significantly increasing cost or weight.
• 48V 105Ah — The most popular 48V option, rated for up to 40 miles. Works well for stock and mildly modified carts used for full rounds of golf or daily neighborhood and community driving.
• 48V 120Ah (Self-Heated) — Built-in heating element allows the battery to charge in cold weather conditions where standard lithium cells would otherwise cut off. Up to 60 miles of range. The best choice for golfers in northern climates or anyone who keeps their cart outdoors in winter.
• 76V 105Ah — Designed for 72V systems including Bad Boy Buggies, GEM cars, and high-performance modified carts. Over 8,000Wh of energy with a 200-amp continuous BMS. Delivers notable improvements in torque and top-end speed on carts where the controller can take advantage of it.
• 76V 170Ah "Godzilla" — Lithium Rhino's flagship kit. Built around 24 Grade A EVE cells, an industry-leading 300-amp continuous BMS, and 170Ah of capacity for up to 70 miles of range. Made for 72V systems and dual-motor or aftermarket controller setups that demand maximum sustained power output.

Which Brand Is Right for Your Cart?

Both brands deliver real performance improvements over lead-acid, but they suit different types of buyers. If you want flexibility — the ability to start small and add capacity later as needed, or if you already own Ionic batteries in another application like a marine trolling motor — Ionic Lithium's modular GC2 system makes a lot of sense. The Bluetooth monitoring is excellent, and the 11-year warranty is one of the best in the category.

If you want a single, complete package where everything arrives together and you don't have to source a charger or figure out wiring, Lithium Rhino is the stronger choice. Their kits are thoughtfully packaged, the included 25-amp charger is genuinely fast, and the 76V lineup is the most extensive we carry for high-performance and 72V systems. The self-heated 48V kit is also unique and worth serious consideration for cold-climate use.

Frequently Asked Questions

Are these kits compatible with my golf cart?

Both Ionic Lithium and Lithium Rhino kits are compatible with all major golf cart brands including EZGO, Club Car, Yamaha, and ICON. The most important thing to verify before purchasing is that the kit's voltage matches your cart's existing system voltage (36V, 48V, or 72V/76V). You can usually find this information on the label of your current batteries or in your cart's owner's manual. If you're unsure, contact us and we'll help you confirm compatibility.

Do I need a new charger when I convert to lithium?

Yes. Lithium batteries require a lithium-compatible charger — a charger designed for lead-acid batteries will not charge a lithium pack correctly and can cause damage or premature failure. All Lithium Rhino kits include a charger in the box. Ionic Lithium bundle kits include the batteries and hardware needed for the conversion, but a compatible charger is sold separately (or may already be included depending on the specific bundle purchased — check the individual product listing for details).

What does a Lithium Rhino kit include?

Each Lithium Rhino kit ships as a complete package: the battery, a 25-amp smart charger, an LCD touchscreen monitor with mounting bracket, a 40-amp 12V reducer for accessories, all necessary wiring and mounting hardware, a drill bit for installation, safety gloves and glasses for lead-acid battery removal, and access to a 30-minute technical installation support call. The Bluetooth app and 8-year warranty are also included.

How does the Ionic Lithium parallel system work?

Ionic Lithium GC2 batteries connect to each other in parallel, which adds capacity (amp hours) without changing the system voltage. A single 36V 27Ah battery stays at 36V; two connected in parallel give you 36V at 54Ah total; three give you 81Ah; and four give you 108Ah. This means you can start with one battery and add more later as your range needs change, rather than replacing the whole pack at once. The batteries fit in the GC2 form factor, the same tray footprint used by most lead-acid golf cart battery setups.

What is the self-heated option on the Lithium Rhino 48V 120Ah kit?

Standard LiFePO4 batteries cannot safely accept a charge below approximately 32°F (0°C) — charging at low temperatures can damage the cells and shorten battery life. The self-heated kit includes a built-in heating element that warms the battery before charging begins when temperatures drop below that threshold. This makes it the recommended option for golfers who keep their cart in an unheated garage, use it in cold seasons, or live in northern climates where freezing overnight temperatures are common.

How long does it take to charge a Lithium Rhino kit?

Using the included 25-amp smart charger, most Lithium Rhino kits reach a full charge in approximately 4 hours from a fully depleted state. Charging from a partial state of charge takes proportionally less time. The charger shuts off automatically when the battery is full.

What is the difference between the 76V 105Ah and 76V 170Ah "Godzilla" kits?

Both are designed for 72V golf cart systems, but the Godzilla is built for high-demand applications. The 105Ah kit uses a 200-amp continuous BMS and is well-suited for most 72V carts including stock Bad Boy Buggies and GEM cars. The 170Ah Godzilla carries a 300-amp continuous BMS, higher capacity for up to 70 miles of range, and is specifically designed for dual-motor setups, all-wheel-drive vehicles, and carts running aftermarket high-performance controllers. If your cart is stock or lightly modified, the 105Ah is likely all you need. If you've upgraded the drivetrain or want absolute maximum performance, the Godzilla is built for that.
