What ga wire do I need ?
I currently have a WFCO 45 amp converter. I have never been happy with it. I have a voltmeter that tells me it is almost always at 13.6 volts. It never drops below that and in 8 years I have only se...

#6 is fine with 55 amps. If you pull wire I believe #4 is the max that will fit the connectors. You may also want to check if you have a fuse or breaker near the battery to verify rating. The PD will charge like a rocket when needed and consistently drop to storage voltage when expected. Make sure the jumper is in the lead-acid position, not lithium. Ampacity with 105C insulation is 100 amps for #6 but it is usually the voltage drop that becomes the size issue. Either way you are fine for now.
