Dry Camper, do you see this single mod with adding a pot /resistor to get 14.8 volts in bulk scaleable to other PD 92XX series chargers, so as to get a set of golf cart batteries up to 14.8V as Trojan recommends? I've bought a 9245C and will mount it within 3 feet of the batteries, and again use some 4 gauge wire. Battery for starters will most likely be a trojan T1275 at 150 amp hours, later the 225 ah Trojan T105's, and it seems topping the charge off fully to the 14.8 to prevent sulphation is something that should be done a few times on a 3 week trip of boondocking.
I've read this thread a couple of times now, and know just enough to be dangerous to my self. Have you looked inside your PD 9245, and would the resistor values be the same to get a 9245 with pendant and the honda 2000 to 14.8 volts. Or am I just better off trying to adjust the PWM 10 amp convertor to finish off the battery daily with 14.8 volts out of a 120 watt portable solar panel? 6.5 amps is not a lot to work with on the solar panel to finish the charge, considering how much the resistance increases in the last 5 to 10% to finish charging.
