I upgraded my off-grid cabin battery bank from lead acid to self-heating LiFePO4 batteries. This off-grid battery upgrade improves winter solar charging performance and overall power capacity dramatically.
Cold weather, limited capacity, and maintenance issues finally pushed me to do a full off-grid battery upgrade, and the results are a huge improvement.
These modern, high tech batteries from Redodo feature built in auto self heating, a smart battery management system with bluetooth and pump out a full 165AH each in a group 31 size case. With 2 of them I have more than doubled my battery capacity compared to 3 or 4 large SLA marine batteries.
I will walk you through the installation and setup of these batteries.
