Lithium House battery

Ok...so if using a DVSR, would i charge with a single bank charger (NOCO 10x1) on the start battery? Or need to go with a dual bank (10x2) and charge each side independent when on shore power?

You want a 2 bank charger, at least 10A per battery, so a 10x2, dvsr inactive when charging on shore power, charger set to appropriate battery chemistry.

It is important to charge each battery separately to allow the smart charger to use its algorithm correctly. If you have batteries in parallel, lets say you had a start and two house batteries in parallel, you’d want to have at least one of the house batteries with its own switch to all three batteries were isolated from each other and of course you’d need a three bank charger.

The 10A per battery is very important, lead acid batteries need a charger with 10-13% of their Amp Hour rating, so a 100 Ah lead acid can use up to a 13A charger. This is super important to proper mix the electrolyte and clean the plates. Every lfp battery that I have seen requires a 10A minimum charger.

Per a written conversation I had with interstate battery, their group 24 75Ah AGM battery can be charged at 25A as long as the voltage does not exceed 14.4V…

If I was running a deep cycle lead acid battery I’d have the flooded type that was maintainable. They need equalizing charges and specific gravity testing to get the most out of them.. easy stuff to do.

I run a NOCO 5x3 for a interstate start battery and x2 lithium liFepO4 100AH. Works great.
