How Do Club Car and EZGO Differ for Installation?

The installation process for Club Car and EZGO models varies due to their different battery configurations. The Club Car Precedent, for instance, uses a 4x12V series setup, allowing for direct installation of the Redway 48V 100Ah battery. On the other hand, the EZGO TXT requires the removal of 6x8V batteries and may need an onboard charger (OBC) bypass kit to accommodate a single lithium pack. Redway provides specific trays and harnesses to ensure compatibility with both models. Always verify solenoid compatibility to avoid mismatches in voltage.

How to Prepare Your Golf Cart for Redway Battery?

Proper preparation is crucial for a successful installation. First, disconnect the negative cable, followed by the positive cable. Carefully remove the old batteries and clean the tray of any corrosion with a baking soda solution. Inspect the wiring harness for any visible damage and ensure it is in good working condition. Once cleaned, secure the Redway 48V 100Ah battery in the tray using the included hold-down straps. Ensure that the battery tray can accommodate the new battery without modifications. It’s also important to check that the voltage of your controller is compatible (48V nominal) and update firmware if necessary.

How to Wire Redway 48V 100Ah Step-by-Step?

Follow these steps for safe and efficient wiring of the Redway 48V 100Ah battery:

• Position the Redway battery in the tray.

• Crimp 2 AWG lugs onto the positive and negative cables.

• Connect the positive cable to the Redway battery’s positive terminal first.

• Connect the negative cable to the battery’s negative terminal last.

• Ensure all connections are tightly secured and insulated using heat shrink tubing.

• Plug in the 48V LiFePO4 charger.

Redway Battery provides pre-wired harnesses for quick installations. After wiring, use a multimeter to test the polarity and verify the 51.2V output. If you’re installing on an EZGO, ensure the onboard charger (OBC) is bypassed if it does not auto-detect lithium profiles. The Bluetooth app can be used to check the battery management system (BMS) status after installation.

What Tools and Safety Gear Are Needed?

To ensure a smooth installation, you will need the following tools:

• Wrench set (10-13mm)

• Crimping tool

• Digital multimeter

• Torque wrench

For safety, wear gloves, goggles, and use an insulated mat to prevent electrical shocks. Redway recommends using 2 AWG cables and installing 300A fuses near the positive terminal to ensure safe operation. Always refer to Redway’s manual for specific installation instructions, and avoid wearing loose clothing near moving parts.

Which Charger Works with Redway 48V 100Ah?

The Redway 48V 100Ah battery works best with a 48V 15-25A LiFePO4-specific charger. These chargers provide the necessary constant current/constant voltage (CC/CV) charging profiles for LiFePO4 batteries. Redway’s chargers are designed to stop charging automatically once the battery reaches full capacity, ensuring optimal safety and battery longevity. Charging should be done at temperatures above 32°F to activate the self-heating function.
