Does a combiner tie both battery sets together when it starts to charge? If
so how do you avoid using the charged battery to charge the discharged
battery?
I would think the isolator even if you went to 400 amps would be a better
deal as long as you use a remote sense alternator. There is a 400 amp full
wave bride on eBay for less than $30 and the $150 amp is less than $10.
What am I missing about a combiner?
