DIY Solar Battery Charger

To build a do-it-yourself DIY solar battery charger you will need to solder the wire from back to front and front to back with three cells. You can wire the cells together for more amps (series) or for more volts (parallel).

You will have two wires on each side of the cell and you need to follow the solder lines that are marked on the cells. After you are finished soldering the three cells together using the back to front and front to back rotation, you now have to do the opposite on the other three, which will be front to back and back to front.

You will build a solar battery charger for a one point five (1.5) array with three cells. If you connect the first set to the second set, you will have a three-volt array. You will also have a wire coming off the front side for the positive connection and a wire off the back for the negative connection. Continue...
