JimBow said:My alternator puts out 105 amps at 750 rpm and 170 amps at 2250 rpm. I ran 6 gauge welding cable from the truck battery to the charger and the charger to the camper battery, and used 60 amp circuit breakers like Victron recommends. I think the Victron Smart 12/12/30 DC-DC charger will be OK with this set up. We'll see!
Having the Victron Smart 12/12/30 DC-DC installed in '05 Tundra....4 gauge wire..w/ 80 amp marine breaker..
