Thanks for the feedback!

40Ahr SLA 'supergel' in fact, though one way or another I might increase that fairly soon...

I'd put my turbine on a charge controller so that it can't overcharge the battery.

Yes, 0.5A@12V would be wonderful, but how many hours per day in winter do you actually get that 0.5A?

Will go and check out "box fan" right now...

Thanks again,

Damon

My "City Wind" at 2 meters high is either none at all, or too much at once.
It won't turn for days, then it gets the battery over-voltage in half a day.

A solar controller will not work with a wind turbine.

Thanks again!

Yes, I understand that I'd need a separate wind controller, but I'm assuming that it will be quite safe to dump power via such as wind controller into the same battery as my solar controller does, providing each controller does its job right.

Really this is all about experimenting with what is possible and at least semi-practical without annoying the neighbours 5 yards away in urban London!
