Solar Battery Charger
I've made a small solar panel array(six panels 0.3 watts each, 3.6 volts each). Sometimes I may want to charge two batteries and sometimes four. So am I correct in assuming that if I have a 4xAA battery holder, and I place two batteries in it, the circuit will not be complete and they will not charge; and if this is so, could I use some sort of jumper between the two empty slots to complete the circuit(it sounds like even if that worked energy would be wasted on the empty slots with the jumpers in place, no?) So would I be better off attaching a set of two 2xAA holders with a dip switch or something? Any help is appreciated.
