Bolt Energy 51.2V 105Ah Lithium Battery Kit for EZGO RXV 48V
SKU 33-402S
The Bolt Energy 51.2V 105Ah "Square" is a complete LiFePO4 lithium battery conversion kit designed specifically for the EZGO RXV 48V electric golf cart (2008 and newer). It replaces the entire lead-acid battery bank with a single 100.8 lb lithium unit, is available in Standard and Professional kit configurations, and is sold by Lithium Battery Supply as an authorized Bolt Energy dealer with full 12-year warranty coverage.
If your EZGO RXV is running on lead-acid batteries, you already know the signs it's time to upgrade: slower performance as the charge drops, batteries that need watering every few weeks, a pack that weighs close to 400 pounds, and a charge routine that takes all night. This kit fixes all of that in one swap.
One battery replaces the entire lead-acid bank. The Professional Kit includes everything needed for a complete conversion battery, charger, solenoid, cables, SOC meter, voltage reducer, mounting hardware, and more. Nothing else to source separately.
What changes after the conversion:
- 20–50 miles of range per charge actual mileage depends on terrain, load, speed, and accessories
- Consistent power from full to nearly empty LiFePO4 holds voltage flat, so your cart doesn't slow down as the charge drops
- ~300 lbs lighter than a full lead-acid bank better handling, less stress on tires and frame
- No more watering, no equalization, no acid cleanup
- Charges in roughly 2 - 4 hours on a standard 110V outlet with the included high-speed charger
- Monitor charge level from your phone via the included Bluetooth receiver and Bolt Energy app
- 12-year warranty 6 years full replacement, 6 years prorated, now fully transferable to a new owner
We are an authorized Bolt Energy dealer. Every battery sold through Lithium Battery Supply is eligible for Bolt's full 12-year warranty. Purchases from unauthorized sellers are explicitly excluded from warranty coverage under Bolt's warranty terms buying from an authorized dealer protects your investment from day one.
Is This Right for My RXV
The most common question we get from RXV owners before buying: "Will this actually fit, and is there anything else I need?" Here's a straight answer.
Fitment
The Bolt Energy 51.2V 105Ah "Square" (BE10551M) is designed for and compatible with the EZGO RXV 48V electric golf cart, model years 2008 and newer. It is Bolt Energy's officially published 105Ah fit for the RXV listed on their manufacturer fitment chart specifically for this model. Unlike some batteries that require a tray-specific profile, the Suqare uses a bracket-mount system: the battery bolts to the floor of the compartment using the included mounting hardware. This means it is compatible with both RXV configurations:
- Plastic tray RXV (most common) bracket mounts cleanly, straightforward install
- Metal tray RXV same bracket-mount approach, same battery, no tray swap required
The Square's dimensions are 12.8″ L × 12.01″ W × 10.42″ H and it weighs 100.8 lbs.
Controller Compatibility
The Bolt Mini is compatible with the stock Curtis and Danaher 48V controllers found in most EZGO RXV models. It does not require a CAN adapter, controller modification, or special wiring for a standard stock-controller RXV. If your cart has been converted to an aftermarket AC motor system or uses a non-standard controller, contact us before ordering and we'll confirm compatibility.

Features
-
LiFePO4 Prismatic Cell Chemistry
Lithium Iron Phosphate is the most thermally stable lithium chemistry available it does not overheat, does not off-gas, and requires no ventilation. Prismatic cells are flat and stacked, giving the Mini its compact square profile and contributing to consistent output across the full discharge cycle. -
Flat Voltage Curve
Lead-acid voltage sags as the battery discharges your cart slows on hills and feels sluggish in the last quarter of charge. LiFePO4 holds voltage essentially flat from full charge to nearly empty. Your RXV performs the same whether the battery is at 90% or 15%. -
Smart BMS Protection
The onboard Battery Management System monitors voltage, current, and temperature in real time. It protects against overcharge (cuts off at 58.5V), over-discharge (cuts off at 40V), and overcurrent (260A sustained / 520A peak for 30 seconds). If a protection event triggers, the BMS disconnects automatically and reconnects when conditions return to normal. No manual reset required. -
Bluetooth Monitoring
The included Bluetooth receiver pairs with the Bolt Energy app on your phone. Check state of charge, voltage, and battery health in real time without opening the compartment. The dash-mounted SOC meter gives you a quick visual read while driving. -
CAN Diagnostic Port
A CAN port is built into the battery for technician-level diagnostics and testing. This is for reading detailed cell-level data it is not required for controller communication on a standard RXV and does not require a CAN adapter during installation. -
IP66-Rated Powder Coated Steel Enclosure
The case is designed to IP66 standard protected against powerful water jets from any direction. Relevant for carts that are washed regularly, exposed to rain, or used in wet conditions on the course or in a neighborhood setting. -
400A Heavy-Duty Solenoid (Professional Kit)
The Professional Kit includes a 400A solenoid sized for lithium systems. Replacing the factory solenoid during conversion is the right call lithium delivers current faster and more aggressively than lead-acid, and an aging solenoid is a common failure point after conversion. -
30A Voltage Reducer (Professional Kit)
Steps 48V down to 12V to power your RXV's accessories lights, horn, USB ports, and any add-ons. The 30A unit included in the Professional Kit handles standard accessory loads cleanly. -
Waterproof High-Speed Lithium Charger
Lithium-specific, waterproof rated, and included in both kit options. Plugs into a standard 110V household outlet and connects via the hardwired AC port installed in the cart. Do not use your existing lead-acid charger it uses a different charge profile and will damage a lithium battery. -
Heated Option Available
A heated version of the Mini is available for owners in colder climates. The standard battery should not be charged below 34°F (0°C). If your cart is stored outdoors in winter or regularly used in cold conditions, select the heated configuration. -
Bracket-Mount Installation
The Mini installs using the included brackets bolted to the battery compartment floor no tray modification, no drilling into the battery itself. This is what makes it compatible with both plastic and metal tray RXV configurations. -
12-Year Transferable Warranty
Effective for 2026 purchases. Backed by Nivel Parts and Manufacturing 6 years full replacement, 6 years prorated. Now fully transferable to a subsequent owner when registered within 15 days of transfer. Lifetime technical support included at no charge.

FAQ
Common questions about the Bolt Energy 51.2V 105Ah "Square" (BE10551M) lithium battery conversion kit for the EZGO RXV 48V golf cart. All answers based on verified manufacturer specifications and official warranty documentation.
Yes. The Bolt Energy 51.2V 105Ah Mini (Square) is Bolt's officially published 105Ah battery for the EZGO RXV it appears on their manufacturer fitment chart specifically for this model. It is compatible with 2008 and newer RXV models running a 48-volt system, in both plastic tray and metal tray configurations.
No. The Mini installs using a bracket-mount system it bolts to the floor of the battery compartment rather than sitting inside a tray profile. The install approach is the same regardless of whether your RXV has a plastic or metal tray. No tray swap, no drilling into the battery.
No. A CAN adapter is not required for a standard EZGO RXV conversion with the Bolt Mini. The CAN port on the battery is for diagnostics only it is not used for controller communication during normal operation. Stock RXV controllers (Curtis or Danaher) work with this battery as-is.
It's strongly recommended and the Professional Kit includes one. Lithium batteries deliver current faster and more aggressively than lead-acid. An aging solenoid from your lead-acid setup may not be rated for the demands of a lithium system. The included 400A heavy-duty solenoid is sized correctly and eliminates this as a concern.
No. Lead-acid chargers use a different charge algorithm and will damage a lithium battery. A lithium-specific charger is required. It is included in both the Standard and Professional Kits you do not need to purchase one separately.
Both include the battery, Bluetooth receiver, SOC meter, charger, mounting hardware, AC hardwire port, extension cord, and manual. The Professional Kit additionally includes a 400A solenoid, 30A voltage reducer, and two 40″ 2AWG premium installation cables.
For the EZGO RXV, the Professional Kit is the right choice it gives you everything needed for a clean, complete conversion without sourcing any additional components.
Most RXV owners see 20–50 miles per charge. Your actual range depends on terrain, total weight in the cart, driving speed, and accessory draw (lights, fans, USB devices). Flat driving at moderate speed on a lightly loaded cart will push toward 50 miles. Hilly terrain with a full passenger load will be toward the lower end of that range.
Lead-acid batteries lose voltage as they discharge, which is why your RXV feels sluggish in the last quarter of charge and struggles on hills when running low. LiFePO4 chemistry holds voltage flat throughout the discharge cycle. With the Bolt Mini, your cart performs the same at 20% charge as it does at 100%.
A standard 48V lead-acid bank for the RXV (six 8-volt batteries) weighs roughly 380–430 lbs depending on the brand. The Bolt Mini weighs 100.8 lbs a savings of approximately 280–330 lbs. Less weight means less stress on the frame, tires, and brakes, and more efficient use of your battery's power.
The battery accepts up to 52A of charge current. With the included high-speed charger on a standard 110V outlet, most owners recharge from near-empty in approximately 2–4 hours compared to 8–10 hours for a lead-acid bank.
Yes. The included Bluetooth receiver pairs with the Bolt Energy app. You can check state of charge, voltage, and battery health in real time from your phone. The dash-mounted SOC meter also gives you a quick visual read while driving.
The Battery Management System monitors voltage, current, and temperature continuously. If any parameter goes outside the safe range overcharge above 58.5V, over-discharge below 40V, overcurrent above 260A sustained or 520A for 30 seconds it disconnects the battery automatically to prevent damage. It reconnects on its own when conditions return to normal. No manual reset needed.
The standard Mini can discharge down to -4°F (-20°C) without issue. However, charging below 34°F (0°C) is not recommended charging a lithium cell below freezing can cause permanent damage. If your cart is stored outdoors in winter or used in consistently cold conditions, select the heated version of the Mini at checkout.
