Vehicle is a Chevy Express, starter battery is lead acid and the lead acid house battery bank on it's last legs.
The house battery battery bank is hooked up to solar. I also added a Cyrix combiner, which acts a bidrectional charger. When the van sits, the solar charges both the house batteries and the starter battery. When the alternator runs, it will charge both the starter battery and the house batteries.
Now, researching upgrading to LiFePO4, I understand you cannot directly connect the alternator to the LiFePO4 and need to use a DC-DC.
Unfortunately, I do not have room for the larger DC-DC units in my build. And most of them (except the $550 renogy 60A) do not support bidirectional charging.
Any ideas for my setup?
