Hello together my first post here and immediately a question: I use my Ford Explorer year 2015 as a microcamper, but without the car really as a camper, I say I have no second consumer battery in the car. In the reason I simply have a mattress in the back and always when I am at the campsite I have all my consumers at an external power source. However, since I often have to get to the car, door open and close, suitcases open and go every time I open the door di e Interior lighting, the display etc. on and consumes electricity from the start battery. I don’t want to remodel the car as I use it as a camper only a few weeks a year, i.e. jam the interior lighting etc. does not come into question. If I stand for a two days in one place I get massive problems with the charge of the start battery and can hardly start the car any more. Now my question: would the problem solve itself and would be that at all possible if I just every time I come to the campsite, connect the start battery to a charger (example CTEK 5.0) and have the charger permanently on until I start again a few days later? According to my understanding, then the battery, which discharges during the day through the indoor lighting etc. in the night will be discharged again and I would have a full start battery the next day. Do I have a thinking error? Thank you for your input in this matter.
