Upgrading a golf cart to lithium batteries increases power, range, and charging speed. The main steps are simple: remove the old lead-acid batteries, clean the tray, install the lithium batteries, connect wiring according to 36V or 48V configuration, install a lithium charger, and test the system. Lithium packs from Redway Battery make installation easier with drop-in, plug-and-play compatibility.
What preparations are necessary before installing lithium golf cart batteries?
Start by turning off the golf cart, removing the key, and setting the tow/run switch to TOW. Wear gloves and eye protection. Confirm the voltage your cart needs (36V or 48V) and ensure the lithium battery pack—such as those from Redway Battery—matches that requirement. Gather basic tools including wrenches, screwdrivers, and a multimeter.

| Tool | Purpose |
|---|---|
| Wrenches / sockets | Loosen and tighten battery terminals |
| Screwdrivers | Remove covers and fasteners |
| Multimeter | Verify voltage and polarity |
How do you remove the old lead-acid batteries safely?
Disconnect the negative cable first to avoid accidental short circuits. Then remove the positive cable. Lift the batteries out carefully—they are heavy and may contain residual acid. Lead-acid batteries must be taken to a recycling center and never disposed of in household waste.
Where should lithium batteries be positioned inside the golf cart?
Place the lithium battery or batteries in the existing tray. Many Redway Battery packs are designed as drop-in replacements, making positioning simple. Secure the pack using mounting straps or brackets to prevent shifting while driving.

How do you wire a lithium battery pack for 36V or 48V?
Connect the batteries according to the cart’s required voltage. Tight and correct connections ensure stable power delivery.
Voltage wiring options
| Cart Voltage | Battery Setup | Connection Method |
|---|---|---|
| 36V | 3 × 12V batteries | Series: positive → negative between units |
| 48V | 4 × 12V batteries or 1 dedicated 48V pack | Series or single pack |
After series wiring, connect the main positive cable to the first battery’s positive terminal and the main negative cable to the last battery’s negative terminal.
What additional components may need installation?
Install a lithium-compatible charger. Lead-acid chargers do not charge lithium properly and may damage the Battery Management System. If your golf cart uses 12V accessories, install a voltage reducer to avoid overvoltage damage. Many Redway Battery kits include the required components for easy installation.
When should you perform the first charge and system test?
Before driving, give the lithium battery a full charge. This optimizes battery balancing and activates the BMS. After charging, perform a short drive. Check acceleration power and monitor the display. Re-tighten connections after the test run.
Why are lithium batteries easier to maintain than lead-acid?
Lithium batteries do not require watering, equalization charging, or corrosion cleaning. Simply inspect connections periodically. If storing the golf cart for more than 30 days, store lithium batteries at around 50–70% charge.
