My friend just got this 18V solar cell from somewhere and since I know a little abuot electronics he asked me to hook it up to a 12V car battery, which he will use for powering his portable stuff(lighting, ham station, camper...)
I know it`s not just positive to positive and neg. to neg., he needs a diode (to asure that he doesnt destroy the cell with reverse curent(or something like that) :?: ) to charge the battery and it would probably work. Except if he over charged the car battery (which could explode ).... We don`t want that to happend so he needs a regulator.
I found some schematics on the net, one seems to sense the voltage on the battery and shunt the cell with some small resistors when the battery is full.
:?: :?:
I just want to know if this can break the cell, if the shunts can draw too much curent for the cell to handle or will the cell survive?
:?: :?:
