I'm trying to figure out the best way to charge my
engine start
battery along with my LIPO4 House bank. It seems the best way to skin the cat here is to use a DC-DC
charger. I would think a trickle
charger here would be fine, as it is only topping the
battery up after a start cycle.
Problem is, the only DC-DC chargers I'm finding are quite spendy ($200 or more) anyone have a recommendation for a basic unit that will keep the house bank isolated from the start side, but still keep the battery charge maintained?
All of my charge sources are wired to only charge the LIPO4 battery, but I could wire it up to enable me to parallel the LIPO4 and the Start battery if necessary via one of the "1-2-both" switches.
