Hello everyone just got me two solar panels at 9v and .5 watt with some plugs for a few rechargables to which i can get any kind but i need some assist i find some circuits online but none are close enouph to take pieces from. What my goal is is to have these 2 panels charge my 9v battery pack this will be used to connect to a few usb ports say 3 at least and so that way i can charge a phone or something plugged into the usb female connectoins to which i also have i know these are 5v and so i bought a whole pack of many resistors with a tm317 variable resistor i think im missing a diode so that the charge doesnt reverse to the panels and something to stop from over charging though i dont know if this would happen being there also 9v panels these should be hooked in series yes?
