How To Install Lithium Golf Cart Batteries On A 36V Or 48V Golf Cart

To install lithium golf cart batteries on a 36V or 48V golf cart, follow these steps:

1. Gather necessary tools: ratchet, protective gear.
2. Disconnect old batteries: cables, wires.
3. Clean battery bay.
4. Charge new batteries fully.
5. Install fuses for safety.
6. Mount new batteries securely.
7. Connect main wires.
8. Test cart functionality.
9. Apply dielectric grease.
10. Monitor and maintain battery usage.

Preparation and Safety Measures:

1. Gather Necessary Tools:
   • Ratchet or socket wrench set.
   • Protective eyewear, gloves, and battery carrying straps.
   • Wire stripping and connecting kit (if using a 12V converter).
2. Safety Precautions:
   • Ensure you have protective gear on to handle lead-acid batteries safely.
   • Use battery carrying straps to protect against corrosion and acid splash.

Removing Old Batteries:

1. Disconnect Cables:
   • Disconnect the primary positive cable first, followed by the primary negative cable.
   • Identify and disconnect wires not connected to other batteries (primary wires).
2. Remove Batteries:
   • Take out the batteries after detaching any remaining cords.
   • Clean the battery bay using a baking soda and water solution if needed to neutralize any battery acid.

Battery Series Connection:

1. Charge Batteries:
   • Ensure batteries are fully charged before connecting in series.
   • Use a 12V charger for balancing, included in Redway Power Lithium packs with 50Ah or more batteries.
2. Fuse Installation:
   • Strongly advise using a fuse between DL+ batteries in series for safety.
   • Install the fuse between the battery positive and the main positive.

Installing New Lithium Batteries:

1. Secure Mounting:
   • Safely mount the new lithium batteries on the cart.
2. Connect Main Wires:
   • Start with the positive wire and proceed to connect all main wires.
   • Apply 10 foot-pounds of torque on each connection.
3. Final Check and Sealing:
   • Double-check all connections before proceeding.
   • Test the cart to ensure proper functioning.
   • Apply dielectric grease to battery terminals to seal them from the environment.

Connecting 12V converter :

• Use a 36/48V to 12V converter to maintain battery pack balance if you have 12V lighting or accessory connections.

Monitoring and Maintenance:

1. Monitoring Battery Usage:
   • Be aware of LiFePO4 battery’s aggressive drain curve for a more precise understanding of usage.
   • Use compatible battery monitors for accurate readings and better battery management.
2. Maintaining Your Battery:
   • Discharge the battery as much as possible before recharging to prolong its life.
   • Use only the Redway Power Lithium charger and maintain charging temperature above freezing.
   • Handle batteries carefully to maximize their lifespan.

By following these steps and safety precautions, you can effectively install and maintain lithium golf cart batteries on a 36V or 48V golf cart, ensuring optimal performance and longevity.
