Trying to charge my lithium battery. Have had this camper for 6 mos with current setup working flawlessly. Have a Bouge RV 12V fridge 23qt which draws minimal amps (45-65approx/day). Camper plugged into 30amp and blows 20amp WFCO fuse. Battery was very low but can’t figure out what else to check to id the problem. Suggestions??

    For clarification, which fuse is blowing? The one that powers the fridge, or the one that powers the battery charger?
    Also, is this one of the newer WFCOs that are supposed to automatically sense whether you're running lead-acid or lithium-iron batteries?

    If the lithium battery charge is very depleted, the draw to charge may well blow the fuse.  We saw this happen on the TaB 400s with a single, large AGM.  NuCamp eventually replaced the fuse with a higher amp fuse.  I would use a lithium specific charger to charge the battery above 50% then see what happens.
