You should consider one of the progressive dynamics chargers. Designed and
listed for RV applications and with the charge wizard, is an excellent
charger. It is also designed to used as a power supply with a clean DC
output so no hum and other noise on your stereo. The Surepower will take
care of charging both batteries.

Subject: Sure Power 1315 question

I'm putting together my aux battery system with a Sure Power 1315
separator. I'm planning on wiring a 120V battery charger to the system
to keep the batteries topped up when parked in my garage. The aux
battery will be a 105 AH deep cycle Diehard and will live under my
rear seat. Starter battery is the usual starter type battery.

Will the starter battery charge (through the 1315) if I wire the 120V
charger to the aux battery? Or would it be better, because of the two
types of batteries, to get a dual bank charger like this Schumacher
and charge each battery independently?
