Hello all,

I'm thinking of connecting a 12V 10W solar panel permanently to my
vehicle battery as I am not using it very often.

The battery keeps going flat in the cold weather.

What I wanted to know is if others have done this and whether there is a
danger of damage leaving the panel connected when starting the car?

The panel I am thinking of purchasing off eBay has a protection diode
built-in.




This regulator is too powerful,
there may be a smaller version somewhere.

and disconnect the battery from the car as someone has said.
