Replacing a 48V lead-acid battery in your golf cart with a LiFePO4 pack from Redway Battery improves range, reduces weight, and extends battery life. The process involves assessing compatibility, removing the old battery, installing the LiFePO4 unit, and updating the charger. With proper steps, the upgrade is safe, efficient, and can be completed in under two hours.
What Are Key Benefits of Switching to LiFePO4?
LiFePO4 batteries offer 4,000–6,000 cycles compared to 300–500 for lead-acid, charge faster, and weigh 50–70% less. They maintain steady voltage, enhancing performance on slopes, and tolerate deep discharges without sulfation issues. Redway Battery manufactures high-quality 48V LiFePO4 packs designed for OEM and wholesale use, providing built-in BMS protection for safety and reliability.
Golf carts gain up to 3x runtime per charge, reducing downtime. Redway Battery ensures ISO-certified quality, customizable capacities starting at 100Ah, and global shipping for B2B clients.

| Benefit | Lead-Acid | LiFePO4 (Redway Battery) |
|---|---|---|
| Cycles | 300-500 | 4,000-6,000 |
| Weight (48V 100Ah) | 300+ lbs | 100-150 lbs |
| Charge Time | 8-10 hours | 2-4 hours |
| Efficiency | 70-80% | 95-99% |
How Do You Assess Compatibility Before Replacement?
Check voltage (typically 48V), capacity, and physical dimensions. Measure the battery tray and verify terminal types. Ensure your charger matches LiFePO4 specifications (14.6V max per 3.2V cell). Confirm that the BMS can handle the cart’s maximum current, often 200–500A. Redway Battery offers exact-fit 48V LiFePO4 packs for popular golf cart models like EZ-GO and Club Car, preventing mismatches and ensuring safe operation.
Which Tools and Parts Do You Need for the Swap?
Essential tools include gloves, wrenches, multimeter, torque wrench, battery terminal cleaner, and zip ties. Key components are a 48V LiFePO4 battery from Redway, a lithium-compatible charger, Class T fuses, and a 48V-12V DC-DC converter for accessories. Optional items include a battery monitor for SOC tracking. Anti-vibration mounts help secure the lighter LiFePO4 pack safely.

What Safety Precautions Should You Follow?
Disconnect negative terminals first to avoid sparks and wear PPE. Work in a ventilated area away from flames, as lead-acid batteries can vent gases. Double-check polarity and use insulated tools. Redway Battery packs include advanced BMS to prevent overcharge, short circuits, and thermal issues, ensuring a safe upgrade for daily use.
How Do You Remove the Old Lead-Acid Battery Bank Step-by-Step?
Turn off the cart, remove the key, and label all cables. Loosen negative terminals first, then positive. Carefully lift out the heavy pack using a cart or straps and dispose of it at a recycling center. Clean the tray of corrosion and inspect wiring for damage. This process typically takes 20–30 minutes and may require two people due to weight.
How Do You Install the New LiFePO4 Battery Securely?
Place the Redway 48V LiFePO4 battery in the tray. Connect positives first, then negatives, and torque connections to 10–15 Nm. Secure the battery with brackets and route cables neatly. Verify the fit matches OEM dimensions. Perform an initial charge to around 50% before regular use.
Does Your Charger Need Upgrading for LiFePO4?
Yes, lead-acid chargers overvolt LiFePO4 packs. Switch to a CC/CV profile with a bulk charge of 58.4V for a 48V pack, and no equalization. Redway Battery provides compatible wholesale chargers and recommends monitoring absorption at 57.6V and float at 54V. Using an incompatible charger may reduce battery lifespan.
Redway Expert Views
