The kit includes a 48V 10A onboard lithium charger with a 10 ft extension cord, a digital Bluetooth battery gauge, a 6 ft remote on/off switch with wiring harness, a fused 12V converter, a cart-specific charge port plug and mounting brackets, with Epoch Li-Ion app monitoring and an IP67 enclosure.
Built to go further
A Complete Lithium Conversion Kit
Upgrade your 48V golf cart without hunting for separate parts.
The Big Box Series LiMAX kit is designed to take the headache out of replacing 48V lead-acid golf cart batteries. Instead of managing water levels, acid corrosion, voltage sag, and a heavy multi-battery bank, this complete 48V lithium golf cart upgrade consolidates your power into one clean LiFePO4 battery system with the core conversion components included.
Fit options for major cart brands
Choose the proper configuration for popular 48V cart platforms, including Club Car Precedent, EZGO RXV, EZGO TXT, Yamaha, and other compatible carts. Always confirm tray fitment, OBC requirements, cable clearance, controller draw, and mounting needs before installation.
A true complete kit
This 48V golf cart battery with charger includes the battery, a 48V 10A onboard lithium charger with a 10 ft extension cord, a digital Bluetooth battery gauge, a 6 ft remote on/off switch with wiring harness, a fused 12V converter, a cart-specific charge port plug and cart-specific mounting brackets, helping reduce hidden add-ons and extra hardware runs. The main fuse or DC-rated breaker for the battery cables is not part of the kit; install one as close as practical to the battery positive terminal.
No watering or acid service
Maintenance-free compared with lead-acid: no water refills, no acid service, and no equalization routines. Routine inspections of the case, terminals, cables, and mounting keep it operating safely.
Transform Your Cart’s Performance
Less weight, stronger response, and lithium power that stays consistent.
Replace a heavy lead-acid bank
A traditional 48V lead-acid golf cart bank can weigh hundreds of pounds. At just 66 lbs, the LiMAX lithium battery can dramatically reduce cart weight, improving acceleration feel, hill response, braking, and suspension load.
Drive further with 65Ah LiFePO4 power
With 65Ah of 51.2V lithium capacity, this kit is built for neighborhood cruising, golf course use, campgrounds, resorts, and utility driving. Range varies by setup, but stock and mildly upgraded carts may see approximately 25–35 miles per charge in normal conditions.
Flat voltage curve for confident driving
LiFePO4 batteries maintain a steadier voltage than lead-acid batteries, helping your cart feel more consistent as the battery discharges instead of sagging early on hills or under load.
Built-In Smart Tech & Rugged Durability
Battery data, dashboard visibility, and waterproof protection.
Bluetooth app & digital dash gauge
The included digital dash gauge shows state of charge, voltage, current, temperature, and warnings at a glance, and the free Epoch Li-Ion app for iOS and Android adds cycle data and battery health on your phone. Firmware updates install over the air through the app.
IP67 waterproof and dustproof
Golf carts get washed, splashed, and driven in changing weather. The IP67-rated enclosure is dust-tight and protected against temporary immersion to 1 m for 30 minutes; it is not rated for water jets or pressure washing.
11-year limited warranty and 3,500+ cycles
The LiMAX battery uses safe lithium iron phosphate chemistry with long cycle life and Epoch’s 11-year limited warranty (5 years of free repair or replacement, then 40% off MSRP on a replacement battery through Year 11; register within 90 days or keep your proof of purchase), making it a long-term upgrade over routine lead-acid replacement.

IP67 Waterproof Protection
Built for rain, washdowns, dust, and real cart use.
The IP67-rated enclosure is dust-tight and protected against temporary immersion in water up to 1 meter for 30 minutes. It is well-suited for wet grass, rain, puddle splash, and regular cart washdowns, but it is not rated for water jets or pressure washing: do not pressure-wash the battery or its terminals, do not install it where it will remain submerged or where standing water collects, and inspect it after any immersion.
Why Upgrade to Epoch LiFePO4?
More usable power, less maintenance, and a lighter cart.
LiFePO4 golf cart batteries deliver a flatter voltage curve, faster recovery, reduced maintenance, and major weight savings compared with lead-acid battery banks. For many EZGO, Club Car, Yamaha, and other compatible 48V carts, the Epoch LiMAX kit is a simpler path to cleaner electric power.
48V 65Ah LiMAX Golf Cart Battery FAQs
Common questions about fitment, range, charging, installation, and monitoring.
Will this battery fit my specific golf cart?
The Epoch 48V 65Ah LiMAX kit is configured for Club Car Precedent, EZGO RXV, EZGO TXT, Yamaha 2007–2010, Yamaha 2011+, and Other (ICON and other compatible 48V carts). It is not a drop-in replacement for every installation: confirm that the battery bay fits the 17.20 × 14.33 × 7.48 in case, and check terminal clearance, cable routing, charge-port wiring, the On-Board Computer (OBC) on Club Car Precedent carts, and that your controller’s current demand fits the battery ratings before installation.
Do I need to buy a separate lithium charger?
No. This is a complete kit and includes a 48V 10A onboard lithium charger with a 10 ft heavy-duty extension cord, along with a digital battery gauge, a remote on/off switch with wiring harness, a 12V converter, a cart-specific charge port plug, and mounting brackets. Do not use an old lead-acid charger unless it is confirmed and programmed for LiFePO4 charging, with equalization and desulfation modes disabled.
How long does it take to charge, and how do I plug in?
About 6.5 hours from empty with the included 48V 10A onboard lithium charger. The charger is powered through the cart’s charge port: the kit’s cart-specific charge port plug replaces the factory lead-acid receptacle (replacing it is required for safety), and the included 10 ft heavy-duty extension cord connects the charge port to a standard 120V outlet. If the charger stays connected, it restarts charging when the state of charge drops below about 95%.
Can I charge the battery in freezing weather?
No. This battery has no internal heater, and the BMS blocks charging outside 0°C to 55°C (32°F to 131°F), so let a cold battery warm above freezing before charging. It can discharge from -10°C to 55°C (14°F to 131°F).
What is the estimated range of the 48V 65Ah battery?
Range depends on cart weight, passengers, terrain, tire size, controller settings, and driving style. Epoch estimates approximately 25 to 35 miles per charge for stock or mildly upgraded carts under normal conditions. For more range, two matched batteries can be connected in parallel for a 48V, 130Ah system.
Will a lithium battery make my golf cart go faster?
In many carts, switching from a heavy lead-acid bank to a lighter lithium battery improves acceleration, hill-climbing response, handling, and braking feel. Top speed still depends on your motor, controller, tires, programming, and local cart settings, but the weight savings and flat LiFePO4 voltage curve help the cart feel stronger throughout the discharge cycle.
Do I need to bypass the On-Board Computer on my Club Car?
Some older Club Car models that use an On-Board Computer to manage the original lead-acid charger may require an OBC bypass when converting to lithium. This is a common part of many Club Car lithium conversions and allows the included Epoch lithium charger to charge the battery directly. Confirm the correct procedure for your exact model year before installation.
Is the 65Ah battery large enough for an upgraded motor or Navitas controller?
The 65Ah LiMAX kit is a strong choice for stock carts and mild upgrades: the battery is rated for 200A maximum continuous discharge, with 300A for up to 15 seconds and 700A for up to 2 seconds for acceleration. Heavily modified carts with high-amp aftermarket controllers, aggressive motor upgrades, oversized tires, or steep hill use may require a larger-capacity LiMAX kit with higher sustained output headroom.
How do I know how much battery life I have left?
The kit includes a digital Bluetooth battery gauge for the dash, which shows state of charge from 0 to 100%, voltage, current, temperature, and warnings. The free Epoch Li-Ion app for iOS and Android shows the same readings plus cycle data and battery health on your phone.
Can I connect two 48V 65Ah LiMAX batteries together?
Yes, in parallel only. Epoch lists this model for up to two batteries in parallel, which create a 48V 130Ah system for extended range. Use matched BB5165A-Kit-1 batteries of similar age, condition, and firmware, charged to the same state of charge, and install them according to Epoch’s configuration guidance. Do not connect them in series.
