Hello
I would like to know which is more important to have a voltage or current regulator.
I have a solar cell that put out 12 volt with around 5 watts output with no load.
I want to use the solar cell to charge Nickel metal hydride battery 1.2 volt.
Want to charge maybe one battery or maybe more than one at different time.
Is there a circuit somewhere that automatic disconnect the solar cell from the battery once the battery is fully charge by the solar cell ?
Thank for the help,mrel
