Key Features

• 48V 65Ah Complete Golf Cart Conversion Kit: One 51.2V (48V class), 65Ah, 3.33kWh LiMAX LiFePO4 battery replaces a heavy lead-acid bank in compatible 48V golf carts; Epoch estimates about 25 to 35 miles per charge for stock or mildly upgraded carts. Choose Club Car Precedent, EZGO RXV, EZGO TXT, Yamaha 2007–2010, Yamaha 2011+ or Other (ICON and other compatible 48V carts); the stainless-steel case measures 17.20 × 14.33 × 7.48 in and weighs 66 lb.
• What's in the Kit: A 48V 10A onboard lithium charger with a 10 ft heavy-duty extension cord, a digital Bluetooth battery gauge, a 6 ft remote on/off power switch with wiring harness, a fused 48V to 12V step-down converter rated 25A with a key-on wire, a cart-specific charge port plug that replaces the factory charging receptacle, cart-specific mounting brackets, and free access to the Epoch Li-Ion app.
• 200A Continuous, 700A Peak: 200A continuous discharge, 300A for up to 15 seconds and 700A for up to 2 seconds for acceleration and hills on stock and mildly upgraded carts. Heavily modified carts with high-amp aftermarket controllers, aggressive motor upgrades, oversized tires or steep hill use may need a larger-capacity kit; size conductors and overcurrent protection to the 200A continuous rating.
• Regen-Ready Charging: Accepts 100A continuous charge current and up to 300A for up to 15 seconds of regenerative braking current. The included 48V 10A charger charges the battery from empty in about 6.5 hours; Club Car carts with an On-Board Computer (OBC) may need an OBC bypass.
• Digital Gauge, App & OTA Updates: The included dash-mounted digital gauge and the free Epoch Li-Ion app (iOS and Android) show state of charge, voltage, current, temperature and warnings, and the app also shows battery health. Firmware can be updated over the air (OTA) through the app.
• IP67 Enclosure & Advanced BMS: Dust-tight and protected against temporary immersion to 1 m for 30 minutes; not rated for water jets or pressure washing. The BMS provides over-voltage, under-voltage, over-current, short-circuit and temperature protection, cell balancing and a low-charge warning.
• Temperature & Bank Limits: Charges from 0°C to 55°C (32°F to 131°F) with no internal heater, and discharges from −10°C to 55°C (14°F to 131°F). Up to 2 batteries in parallel (130Ah); series connection is not supported.
• 3,500+ Cycle Life, No Watering: Rated for 3,500+ cycles, with no watering or acid service; routine inspections of the terminals, cables and mounting keep it operating safely.
• 11-Year Limited Manufacturer Warranty: Covers qualifying defects in materials and workmanship under normal use, subject to Epoch Batteries' warranty terms. Register within 90 days of purchase for full coverage.

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 warranty and 3,500+ cycles: The LiMAX battery uses safe lithium iron phosphate chemistry with long cycle life and Epoch’s 11-year limited manufacturer warranty (register within 90 days of purchase for full coverage), 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.

Please Note: Not a drop-in replacement for every installation: confirm the battery bay fits the 17.20 x 14.33 x 7.48 in case, and check terminal clearance, cable routing, charge-port wiring, the Club Car Precedent On-Board Computer (OBC) and your controller's current demand before installation

Please Note: Installation should be done by an authorized mechanic or technician

Please Note: Not included: a main fuse or DC-rated circuit breaker for the battery cables; install one as close as practical to the battery positive terminal

Please Note: Size conductors and overcurrent protection to the 200A continuous rating; heavily modified carts with high-amp aftermarket controllers, aggressive motor upgrades, oversized tires or steep hill use may need a larger-capacity kit

Please Note: Replacing the factory charging receptacle with the included cart-specific charge port plug is required for safety
