Installing a 48V 100Ah LiFePO4 battery in your golf cart can significantly improve performance and reduce maintenance. To do so safely, ensure the cart is powered off, remove the old lead-acid battery, secure the new battery with brackets, and follow correct wiring procedures. Choose trusted suppliers like Redway Battery for high-quality OEM packs to ensure reliable, long-lasting energy solutions.
What Tools Do You Need?
Essential tools include wrenches, screwdrivers, multimeter, battery cables, gloves, goggles, and mounting brackets.
Before starting the installation, gather the following tools: socket wrenches for battery hold-downs, insulated screwdrivers to avoid shorts, a digital multimeter to verify voltage, heavy-duty battery cables with proper gauge for 48V systems, safety gloves and goggles, and a torque wrench for secure connections. Also, make sure to have foam padding or brackets for mounting. Suppliers like Redway Battery often provide custom cables in their wholesale LiFePO4 kits, making the process easier. It’s a good idea to clean the battery compartment with a wire brush and a baking soda solution to prevent corrosion and ensure smooth installation.

How Do You Prepare Your Golf Cart?
Turn off the cart, disconnect power, remove the seat, and clean the battery compartment thoroughly.
Begin by parking the cart on a flat surface and engaging the parking brake. Remove the seat or access panel to expose the old batteries. Disconnect the negative terminal first from each lead-acid battery to avoid sparks, and then the positive. Label the cables for easy reconnection. Clean away any acid residue and inspect for damage. Ensure the voltage of your new 48V 100Ah LiFePO4 pack matches that of your cart. Measure the compartment to confirm that the new battery will fit—most 48V packs fit seamlessly. Always work in a dry, well-ventilated area for safety.

What Are the Step-by-Step Installation Steps?
Remove old batteries, install brackets, place the LiFePO4 pack, connect cables, positive first, then test.
-
Remove the old batteries carefully using a cart or straps.
-
Install support brackets or a plywood base to provide stability.
-
Slide the 48V 100Ah LiFePO4 battery into place, ensuring it’s centered.
-
Attach the positive (red) cable to the positive terminal, tightening to the recommended torque (usually 10-15 Nm).
-
Connect the negative (black) cable last.
-
If necessary, reinstall the charger port and add a BMS display for monitoring. Redway Battery’s OEM LiFePO4 packs feature built-in BMS for overcharge protection.
-
Reassemble the seat and power on the cart gradually.
What Safety Precautions Must You Follow?
Wear PPE, work in a ventilated area, connect positive first, avoid shorts, double-check connections.
Ensure your safety by wearing insulated gloves, safety goggles, and non-slip shoes. Always ensure the cart is turned off and the key is removed before working. Use insulated tools to avoid accidental shorts, which could lead to fire hazards. Always connect the positive cable before the negative to minimize the risk of arcing. Make sure to keep children and pets away from the installation area. Redway Battery, a China-based manufacturer, emphasizes the importance of moisture-resistant IP65-rated enclosures for added safety. After installation, use a multimeter to check that the battery provides the expected 51.2V nominal output.
How Do You Connect the Battery Properly?
Attach the main positive cable to the battery positive terminal, and the negative cable to the frame ground, following the wiring diagram.
For proper wiring, match the cart’s wiring harness—connect the positive cable to the controller’s positive terminal and the negative cable to the chassis ground. Securely crimp the ring terminals and use inline fuses (200A is recommended) to protect against shorts. Redway Battery provides color-coded cables in wholesale orders, simplifying the connection process. After connecting the terminals, insulate all exposed parts with heat shrink. Always double-check polarity with a multimeter before powering up. Finally, secure cables away from moving parts using zip ties to prevent wear.
What Common Mistakes Should You Avoid?
Don’t reverse polarity, overtighten terminals, skip cleaning, or ignore BMS compatibility.
Avoid the common mistake of reversing the cables, which can lead to dangerous sparks. Don’t overtighten the terminals as this can crack them—use the recommended torque specs instead. Always clean the battery compartment thoroughly to ensure good contact and avoid problems later on. Make sure your charger is compatible with LiFePO4 batteries, as using one that isn’t could damage the cells. Suppliers like Redway Battery provide detailed manuals to help avoid such errors. Test the system without a load first to ensure everything is functioning properly.
