Checked my battery voltage yesterday & its up to nearly 20 volts :shock:
Its always been a bit higher than I would have liked, but now it seems I have no cut off voltage on my regulator.
Would the fact that I'm only using a 7Ah battery have anything to do with it?
I'm using a 10 watt panel. Is there a chance it thinks its a 24v system & has been trying to top up to 24 instead of 12?
Time for a new charge controler I think. Any recomendations on a cheap reg?
