The Epoch 48V 230Ah LiMax Series LiFePO4 Golf Cart Battery Model BB51230A is a complete lithium iron phosphate conversion kit for 48-volt electric golf carts. It stores 11.776 kWh of energy in a sealed steel enclosure rated IP67 for dust and water resistance, and is rated for 4,000 charge cycles with zero maintenance required. Nominal Voltage 51.2V a 48V system
If you currently have lead-acid batteries in your golf cart, this is what switching to lithium means day to day: no more watering batteries every few weeks, no more acid smell in the garage, and no more watching your cart slow down on the back nine as the charge runs low.
With 11.776 kWh on board, golfers using a standard 2-passenger cart on flat terrain can realistically complete multiple rounds between charges. For carts carrying more passengers or operating on hilly terrain, capacity is still significantly higher than a standard lead-acid pack. Actual range depends on your specific cart, load, terrain, speed, and accessories, see the FAQ tab for estimated figures.
The Epoch 48V 230ah charges overnight using the included 48V lithium charger. Plug in after your last round or your last neighborhood run, and wake up to a full battery. No memory effect, no equalization cycles, nothing to monitor. The built-in Battery Management System handles everything automatically.
A free Bluetooth app for iOS and Android lets you check your battery's state of charge, voltage, current, cell health, and temperature from your phone at any time. Firmware updates for the BMS are delivered over the air through the same app, no service visit needed.
The steel case is rated IP67 dustproof and waterproof to one meter for 30 minutes. The battery discharges reliably from -4 degrees F to 140 degrees F without a built-in heating element, making it suitable for year-round use in most climates. Charging is supported between 32 degrees F and 131 degrees F.
Before ordering: This battery weighs 196 lbs and measures 23.5 inches long x 14.4 inches wide x 9.9 inches tall. Confirm your battery compartment fits these dimensions before purchasing. Fitment depends on your specific cart model and year not the brand name alone. Two people are required for safe installation. Contact us with your cart's make, model, and year before ordering and we will help confirm compatibility.
Up to two BB51230A units can be connected in parallel for a combined 23.552 kWh. Two units is the manufacturer-specified maximum for this model. Covered by Epoch Batteries' 11-year manufacturer warranty.

Features
11.776 kWh Energy Capacity. High-capacity storage for golf carts with heavy daily use, multiple passengers, or hilly terrain. Actual range depends on cart, load, terrain, and conditions, see the FAQ tab for estimated figures.
LiFePO4 Chemistry Stable Voltage Throughout Discharge: Power output remains consistent from the start of each charge to the finish. No gradual fade, no slowdown as the battery depletes. Performance at the end of a round matches performance at the start.
4,000-Cycle Rated Life, At one full charge cycle per day the manufacturer-rated life exceeds 10 years.
Zero Maintenance Required: No watering, no equalization, no terminal cleaning. The BMS handles all cell balancing automatically throughout the battery's life.
IP67 Waterproof Steel Case: Dustproof and waterproof to one meter for 30 minutes. Steel construction withstands outdoor conditions, rain, and course use.
300A Continuous Discharge / 1,000A Peak: Supports high-draw controllers and steep terrain without BMS cutoff. 300A continuous, 500A for 15 seconds, 1,000A for 2 seconds at peak.
Discharge to -4 Degrees F Without a Heater: Operates reliably in cold weather without a built-in heating element. Charging requires temperatures at or above 32 degrees F.
Bluetooth Monitoring Free iOS and Android App: Monitor voltage, state of charge, current, cell health, and temperature in real time from your phone.
Over-the-Air Firmware Updates: BMS updates delivered wirelessly through the Epoch app. No service visit required.
No Hydrogen Off-Gassing: Safe to charge and store in an enclosed garage. LiFePO4 does not produce hydrogen gas during charging.
Parallel Expandable: Connect up to two units in parallel for a combined 23.552 kWh. Two units is the manufacturer-specified maximum.
Complete Conversion Kit: Charger, mounting hardware, 12V converter, and state-of-charge gauge all included. Ready to install on arrival.
UL, CE, and RoHS Certified: UL 1642, UL 9540A, IEC 62619:2022, CE, and RoHS certified. Ships under UN 38.3 classification.

FAQ
Will this battery fit my golf cart? What brands does it work with?
This battery is designed for 48-volt electric golf carts. The most common 48V platforms it is installed on are EZGO, Club Car, and Yamaha. However, fitment depends on your specific model and year not the brand name alone. Compartment size and wiring configurations vary between models, even within the same brand.
Before ordering, confirm all three of the following:
Your battery compartment physically fits the battery dimensions: 23.5 inches long x 14.4 inches wide x 9.9 inches tall
Your cart runs on a 48-volt system not 36V or 72V. Check your current battery labels or your owner's manual if you are unsure.
Your motor controller is compatible with a LiFePO4 lithium battery at 51.2V nominal voltage
Contact us before purchasing if you are not certain. Send us your cart's make, model, year, and battery compartment dimensions and we will help you confirm fitment before you buy.
