Wind powered battery charger
HI.. this is my first post on these forums.
I want to build a small windmill that will charge ordinary rechargeable AA sized batteries.
however there's a problem.
I have hooked up my windmill to a motor which produces DC current. Now, the motor provides enough and MORE current to charge the batteries. My problem is how do i protect the battery from overly high voltages and currents that may be generated by the motor?
