48V Lithium Batteries

Maximize Efficiency with Premium 48V Lithium Batteries

Traditional 48-volt power banks often rely on four 12V, six 8V or eight 6V lead-acid batteries connected in series. That arrangement fills the battery tray with heavy cases, jumper cables and corrosion-prone terminals while adding routine watering and cleanup to ownership. A common six-battery golf cart bank can weigh well over 350 pounds before hold-downs and cabling are counted.

Epoch 48V lithium batteries replace that complexity with native 51.2V LiFePO4 power. A correctly sized 48V LiFePO4 battery can reduce weight, provide more usable deep-cycle energy and maintain steadier voltage under load. The collection supports applications ranging from golf carts and electric marine propulsion to RV, skoolie, solar, backup and high-power inverter systems.

Current options include a modular 30Ah GC2 battery, complete 65Ah through 230Ah golf cart kits, rugged 100Ah Elite batteries and a scalable 100Ah server-rack platform. Cycle-life ratings vary by model from 3,500+ to 6,000+ cycles, and every model currently shown in this collection carries an 11-year manufacturer warranty.

The Single-Battery Revolution: Ditch the Heavy Lead-Acid Bank

Moving to a native 48V lithium battery can simplify a compatible system in several important ways:

• Major weight reduction: Six commonly used 63-pound 8V flooded batteries weigh approximately 378 pounds. By comparison, Epoch's 48V 65Ah golf cart battery weighs about 66 pounds and the 105Ah model weighs about 99 pounds. Exact energy and runtime are not identical, so always compare capacity and output as well as weight.
• Fewer external connections: A single 48V pack removes the five series jumpers found in a six-battery bank. Fewer exposed connections can reduce cable clutter and simplify inspection, although the main cables, fuse or breaker, charger and mounting still need to be engineered correctly.
• Unified cell management: One internal Battery Management System monitors the complete pack and provides model-specific protection against overcharge, excessive discharge, overcurrent, short circuits and unsafe temperatures. Separate low-voltage batteries can drift apart when they differ in age, capacity or state of charge.
• More consistent power: Lead-acid voltage declines as the bank discharges and falls further under heavy current. LiFePO4 has a flatter discharge curve, helping a compatible golf cart, inverter or motor maintain steadier performance through most of the usable cycle.
• No watering or acid cleanup: Epoch LiFePO4 batteries require no electrolyte checks or distilled-water service. Normal maintenance still includes inspecting cable condition, terminal torque, hold-downs, ventilation around power electronics and overcurrent protection.

48V LiFePO4 vs. Lead-Acid Voltage Discharge Curve

The representative graph below shows why a 48V lithium system can feel stronger later in the discharge. A 51.2V-nominal LiFePO4 pack remains near its working voltage through most of the cycle, while a 48V lead-acid bank loses voltage more progressively as stored capacity is used.

Top Applications for 48-Volt Lithium Power

48V Golf Carts: Club Car, EZGO and Yamaha

A 48V golf cart battery is a popular upgrade for compatible Club Car, EZGO, Yamaha and other modern cart platforms. Epoch complete kits combine the battery with a lithium charger, dashboard gauge, 48V-to-12V converter and configuration-specific mounting components. Options range from the lightweight 48V 65Ah kit to 105Ah, 150Ah and 230Ah systems for longer-range or higher-demand builds.

“Drop-in” describes easier physical fitment, not universal electrical compatibility. Verify nominal voltage, battery-tray dimensions, controller and motor current, regenerative-braking limits, cable routing, charger installation, accessory power and any Club Car onboard-computer requirements before completing a 48 volt lithium golf cart conversion.

Off-Grid Solar, RV and Skoolie Systems

A 48V off-grid solar battery is well suited to large inverter systems because higher voltage reduces DC current for the same wattage. A 5,000W load is approximately 98A at 51.2V before conversion losses, compared with about 391A at 12.8V. Lower current can reduce voltage drop, cable heating and conductor-size requirements when the entire system is designed correctly.

Epoch's 48V 100Ah V2 Elite battery stores 5.12kWh, supports 150A continuous output and provides native Victron CANbus communication for compatible GX systems. The 48V 100Ah server-rack battery also stores 5.12kWh and supports CAN/RS485 communication with configured inverter ecosystems. A 48V build normally needs DC converters for appliances designed only for 12V or 24V.

Marine Electric Propulsion and High-Voltage Motors

Selected electric outboards and propulsion platforms operate on 48V battery power, making a 48V marine lithium battery useful for correctly engineered boats. Confirm the motor's operating-voltage window, continuous and peak current, communication requirements, emergency disconnect, charger and manufacturer battery guidance. A matching voltage alone does not guarantee compatibility with every outboard or trolling system.

Sizing Your 48V System: How Many Amp Hours Do You Need?

30Ah Modular GC2 Power

The 48V 30Ah GC2 battery stores 1.54kWh, weighs approximately 33 pounds and supports 60A continuous discharge. It is designed for light-duty use or modular parallel banks. Epoch lists support for up to ten matched units in parallel, allowing 60Ah, 90Ah, 120Ah and larger configurations while retaining a familiar GC2-style footprint.

65Ah for Golf, Neighborhood and Light Utility Use

The 65Ah complete kit stores approximately 3.33kWh, weighs 66 pounds and supports 200A continuous discharge. In many stock or mildly upgraded carts, Epoch estimates approximately 25 to 35 miles per charge under normal conditions. Actual range varies with terrain, passenger load, tire size, lift height, controller settings, speed, temperature and driving style.

100Ah and 105Ah: The Versatile Middle Ground

A 48V 100Ah lithium battery stores approximately 5.12kWh and is a practical starting point for solar, marine, RV and high-power inverter systems. For golf carts, Epoch's 48V 105Ah complete kit stores approximately 5.38kWh, weighs 99 pounds and supports 200A continuous output. Many standard carts may see an estimated 35 to 45+ miles per charge, subject to vehicle setup and conditions.

150Ah and 230Ah for High-Demand Builds

The 150Ah golf cart kit stores approximately 7.68kWh and supports 300A continuous output, while the 230Ah kit stores approximately 11.78kWh with the same 300A continuous rating. These larger options suit compatible lifted carts, passenger vehicles, utility use and other applications with substantial energy demands.

Parallel limits vary significantly by product. Current golf cart kits commonly allow two matched batteries in parallel, the 30Ah GC2 platform allows up to ten, the V2 Elite supports up to sixteen and the server-rack model supports up to thirty-two. Follow the exact manual for matched-battery requirements, busbars, fusing, communication wiring and charger sizing.

The Epoch Advantage: Smart Technology and System Integration

• Model-specific communications: Bluetooth-equipped products provide app-based state of charge, voltage, temperature and battery-status data. Select Elite batteries provide native Victron CANbus integration, while the server-rack platform supports configured CAN/RS485 communication with multiple inverter ecosystems.
• Cold-weather protection: Select Elite and server-rack batteries include internal heating for safe charging in freezing conditions. Golf cart models may instead use low-temperature charging protection without active heating, so check the exact product before planning a cold-weather installation.
• Application-specific enclosures: Current golf cart kits and V2 Elite batteries are IP67 rated for dust and temporary water exposure. The server-rack battery is IP20 and belongs in a dry, protected indoor enclosure. No IP rating replaces secure mounting, terminal protection or correct cable routing.
• Stable LiFePO4 chemistry and smart BMS protection: Lithium iron phosphate is valued for strong thermal and chemical stability. The integrated BMS adds electrical and temperature protection, but proper fusing, disconnects, cable sizing, charging settings and installation remain essential.
• 11-year manufacturer warranty: Every battery presently displayed in Epoch's 48V collection includes an 11-year warranty. Cycle life, certifications, output and environmental protection vary by model, so review the individual listing before purchase.
