Made this awful mistake of not doing pre-prep work before going away on our next camper trip (now). Discovered this morning that some (idiot) person had turned off the power to the camper trailer and the battery was basically dead. I just hope it’s not “dead dead”. We plan to leave after 4hrs of Bulk Charge from the mains power and it’s internal battery charger and hope for the best. I’m also brining a spare 12.8V LifePo4 battery that is basically full to power the fridge, just in case. Fark I’m an idiot 🤦‍♂️
