I have a solar battery charger that I built, it's pretty simple, just a solar panel, a charge controller, and a set of batteries...
Originally I built it (off of directions, mind you) with 8 AA batteries in series- so 12 volts- but I would like it if it could be run with only 4 AAs...
what, if anything, would I need to change (do I need something to step down the voltage?) to make it work with this.
Ideally as simple and small as possible, the entire thing is inside a waterproof box of limited size....
thanks,
Daniel
