Deka DC31DT battery? Deep Cycle?

And there's your biggest issue ... probably wired with way too much 6 gauge to get to the battery location and almost for sure never bulk charges at it's advertised 14.4 volts. It's the same problem I and just about every other WFCO owner has :M ... I solved mine by turning the darned thing off and instead using a portable charger that does do a proper 14.4 volt bulk charge and is wired directly to the battery with 6' of 4 gauge.

Fact is, charger and battery are directly related - buy a Trojan and you're going to want to bulk charge at 14.8 volts, buy a Deka AGM and you'll want temperature compensated charging which almost no converter / charger is capable of. Getting the most out of whatever batteries you buy isn't just a matter of comparing battery to battery but also matching those batteries to the charger you intend to use to maintain them. Ignore it and you can bet you'll be replacing those batteries sooner rather than later. :(

I was hoping to get away with maybe just replacing the wiring from the converter to the batteries with heavier wire for now and upgrading the converter down the road.

I read that good improvements can be had by upgrading that run. The inverter will be near the batteries as everyone has suggested.

We are planning on a couple of "dry runs" in the next few weeks, probably in Camp Driveway as we test usage and charging/recovery, etc.

Hoping this will tell us:

1. Do we need a 3rd 12v Group 31 battery
2. Must we urgently upgrade the converter/charger
3. Are our inverter/battery bank/wiring/expectations well matched
4. Does everything else work? Any problems electrically or otherwise?

I have some welding cable somewhere I'm going to see if I can find. I also have access to long 4 conductor cable used to power old mobile homes. Have to check the gauge.

We'll upgrade the converter/charger now if we must. Sounds like it is likely?

Thanks guys for sticking with this ;)
