Batteries at 20 Volts!!!

Eeeeeeeeeeeeek!
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?

Crissis averted.

Checked a few other voltages with my meter & found they were all coming in at around 19 volts. Not bad for a PP3 :lol:

Anywho, decided to change the battery in my meter just in case. Normallity restored. I can breath easily now, I'm not cooking my batteries.
