To convert to lithium batteries, replace your old batteries, and then upgrade your charging system to match the lithium battery's requirements, which includes adjusting charge controllers, chargers, and potentially replacing the isolator with a DC-DC converter. Ensure the new battery physically fits in its compartment, use proper wiring and safety connectors, and connect the batteries in a safe configuration (series or parallel) to meet the required voltage or capacity.
1. Remove old batteries and assess your system
Disconnect and remove the old lead-acid batteries.
Take pictures of the existing wiring before you begin, so you can reference it later.
Keep the old battery out of tow mode before disconnecting wires, if applicable.
2. Update or replace charging components
Your old lead-acid charger is likely incompatible, so you will need a new one designed for lithium batteries.
Adjust charge controller settings: Configure your solar charge controller for the correct lithium profile, as the voltage requirements are different.
Replace isolator with DC-DC converter: If you have a battery isolator between your starting battery and house batteries, you must remove it. Replace it with a DC-DC converter to provide the correct charging profile for your new lithium batteries.
Connect to power sources: Connect solar panels and shore power to the new DC-DC converter or the new lithium charger.
3. Install and wire new batteries
Ensure the new lithium battery will fit in the existing compartment, possibly needing an adapter or to modify the space.
Use wiring and connectors that are rated for lithium battery systems.
Connect multiple batteries in parallel or series to achieve the desired capacity or voltage, following the manufacturer's guidelines.
For safety, consider using a bus bar with a fusible link for connecting multiple cells in parallel to prevent disaster if one cell fails.
4. Secure and test the system
Securely mount the batteries to prevent movement or vibration, especially in RVs or boats.
Install a battery box for outdoor environments like in an RV trailer.
Test the new system thoroughly to ensure all components are working correctly.
