Last week the battery was reading a Healthy 13v on the electric panel. I used the mover whilst parking up a couple of weeks ago but week had the battery charger running off the generator for a good hour. Today it’s reading 9V and flashing E1 which I’m guessing is an error relating to low voltage. As far as I’m aware there were no lights left on. I may have forgotten to power down the panel would / could this have drained the battery? Any how, I’m taking it home to charge.
