The charger was an option therefore not a necessity ,so it can wait. I was just going over the manual & thought , that would be nice to have. Only to discover that option was omitted on mine. Perhaps someone will be parting out & have one i could purchase,the way it looks for now i'd have to buy the whole hi-lo to get a part..
I think you need to investigate more, since all the lights inside most of the hilo's (if not all still) were run from the 12 battery, plus the pump that raises the camper, the water pump, and the fridge's control cuircuits & exhaust fan, plus the fan in the vent of the bathroom is so equipped run off the "house" battery wich is a car sized deep cycle battery. So, it seem unlikely that the inverter you have doesnt send 12v to the battery in some way... otherwise while you camp the battery (lights and lift pump, and all that) would become inoperable when the battery was drained, even though you have the camper plugged into 120v. IMHO, and a guess, the "battery charger" option, I would only speculate to say maybe some camper/inverter combo that has a generator that has it's own battery in its own location, would been in need of this circuit?
FWIW, my generator also uses the same house battery to run it's starter, so again if battery is dead, everything I can think of is dead, except the air conditioner, but you know it doesnt run off the battery, only the power cord.
