I'm looking at upgrading my 4D batteries to Battle Born LiFePO4. I will be going with 300 Ah plus a lead acid start battery.
Battle Born suggests that I upgrade the alternator to the 105 amp alternator available from Catalina Direct and install a Li-BIM from Precision Circuits in order to get maximum charging benefit while the engine is operating.
I've been doing a lot of research and have not been able to find anyone comment about installing the Li-BIM in a boat. Everyone installs it in their RV. I talked to the tech at Precision Circuits and he assured me that their product is fully waterproof and compatible with marine installations.
My first inclination was to install a DC-DC charger but Battle Born got me thinking that the Li-BIM would be a better option given the Ah of batteries to charge.
Any comments from the forum would be appreciated.
