  • Cheap Voltage Regulated Joule Thief power supply/charger

    Just what i needed! I was given 4 old giant batteries, 2v at 600ah each. My whole solar panel setup lights and stuff is designed for 12v. I solved the charging using Renes re-emf charger that self regulates. However now i need a step up regulator for the output to my lamps and stuff. But i'm completely ignorant of elecronics, i can only follow schematics and assemble without having the slightes clue bout how it works. Is there any chance u could tell me the voltage and amperage ratings i should get for the components with my batteries? Pleaaaaaaaase!????
