How Should You Prepare For Battery Installation?
Preparation is key to safe and efficient installation:
-
Work Area: Ensure the workspace is well-ventilated.
-
Protective Gear: Wear gloves and safety goggles at all times.
-
Cart Settings: Switch the cart to “tow” mode and turn off the ignition.
-
Disconnect Power: Remove any charging sources and disconnect the main negative cable first, followed by the main positive cable.
-
Document Wiring: Take photos of existing connections to guide reinstallation.
How Do You Remove Old Lead-Acid Batteries?
-
Disconnect Cables: Start with the main negative terminal, then disconnect the main positive. Detach any secondary or accessory wires.
-
Remove Batteries: Lift batteries using straps or assistance to avoid injury.
-
Clean the Compartment: Use a baking soda and water solution to neutralize acid residues and remove corrosion.
Proper removal ensures the new Redway Battery lithium packs are installed in a clean, safe environment.

How Do You Install New Lithium Batteries?
Secure Mounting
Place the new lithium batteries in the compartment, ensuring proper orientation. Use mounting brackets or straps to prevent movement during operation.
Wiring Connections
-
Series Configuration: For multiple 12V lithium batteries in a 36V or 48V system, connect them in series (positive to negative) according to the manufacturer’s diagram.
-
Main Cables: Connect the main positive cable first, followed by the negative.
-
Torque Settings: Use a torque wrench to tighten connections to recommended specifications (typically 10 foot-pounds).
Fuse Installation
Install a fuse between the positive terminals of batteries connected in series to protect against short circuits and enhance safety.
Accessory Integration
Install a 36/48V to 12V converter for lighting or other 12V accessories to prevent draining the main battery pack.
Charging
Charge new batteries fully using a Redway Battery LiFePO4-compatible charger before first use to activate the Battery Management System (BMS) and ensure balanced cells.
How Do You Test And Maintain Your Lithium Batteries?
-
System Test: Turn the cart from “tow” to “run” mode and verify all functions, including lights, horn, and motor performance.
-
Apply Dielectric Grease: Seal battery terminals to prevent corrosion and environmental damage.
-
Monitoring: Use a compatible battery monitor to track voltage, state of charge, and discharge patterns.
-
Maintenance: Discharge fully before recharging and avoid charging below freezing temperatures. Handle batteries with care to maximize lifespan.
| Maintenance Tip | Recommended Practice |
|---|---|
| Charging | Use only Redway Battery-approved chargers |
| Storage | Store fully charged in a cool, dry place |
| Cleaning | Wipe terminals and apply dielectric grease regularly |
