While I am not an electrical guru, I second Karl's recommendation for the
Iota unit. Four years ago I searched for a battery charger to use with my
Truck Fridge and the 4 motorcycle battery axillary setup and after
extensive online research, I decided on the IotaI # DLS - 30/IQ4 series M
battery charger, 12 volt / 30 amps with built-in controller. Part of the
decision was driven by the size of the Iota since I could install it
beneath the fridge location and part of it by the Iota tech support.
Before and after the sale, Iota tech support could not have been more
helpful. They quickly responded to any emailed questions and provided
clear answers. After 4 years of use, everything is still working perfectly.
