    2021 Solitude 3550BH battery charging issue help

    Looking for any tips on troubleshooting a battery issue I am having and I will be working through tonite to try and fix in time for a trip this next weekend. Checked the camper this weekend and found the batteries dead which was a surprise, I thought the battery switch was off and should have been sitting at about a 75% charge after watching my Victron patterns. Related or unrelated clue I tried plugging the camper into a 20amp extension cord outlet thinking it should be able to run the inverter and charge things back up. The GFI would pop after about an minute no matter how much I checked to make sure everything was turned off that might be tripping the breaker with overload like AC, water heater etc. On my old camper I was always able to plug in using the same procedure and never had the GFI trip issue. I hooked up my portable generator and plugged the camper in that way for two hours to try and start the recharge process and the camper worked when running off generator power. I shut off the generator and checked to see what my Victron said for battery state and everything is dead again. Tonight when I have more time, I am going to check the WFCO battery charger and see if it has any power output. Is their a fuse that would affect the charging I should be looking for? Anyone have any other tips as I try to get this fixed ASAP for next week's trip? I don't know if that popping GFI is a clue to this overall problem? I've always been able to plug in and kept my batteries charged and yes i've used proper 12ga 50ft extension cords that should have been able to carry the current without significant voltage drop or heat etc.

    Thanks

    My first question is what type of battery(ies) do you have? Flooded lead acid, AGM, carbon foam, LiFePO, or something else?

    Second, if it is anything other than a LiFePO battery(ies), have you tried a car battery charger? I recommend disconnecting both battery cables, going to the coach and just charging the battery(ies) with the car battery charger at it's highest amperage setting. Then, after a few hours, remove the charger and check the battery(ies) with a multimeter. If they read anything less than about 11.5 volts, you have a dead battery(ies) and will need to replace it(them).

    If it's a LiFePO battery(ies), you can still use a car battery charger to try to get some kind of charge into it(them) and, like above, remove the charger and check with a multimeter. For a LiFePO battery, anything less than 8 volts means it's dead. To be safe, no less than 11.5 volts. A LiFePO battery that has been discharged to below 8 volts should still take a charge, however, damage may have occurred.

    Since they are flooded lead acid, I'm going to go out on a limb here and say that you have at least one (probably both) bad battery(ies). Now would be a good time to replace them with AGM, or 4 - 6v golf cart batteries (there are other threads out there that discuss how to connect the 6v batteries).

    I would also put in a battery disconnect switch https://smile.amazon.com/dp/B00445KF...ing=UTF8&psc=1, right off the battery, so it kills power to the entire coach when in storage. We do that and just use a car trickle charger, or a 50 watt solar panel with a cheap MPPT solar charge controller, just to keep them topped of when in storage.
