Hello,
I did a standalone device (xbee, pir, battery). My issue is the duration of the batteries.
That the reason why i am trying to create a solar power system with a 12v solar panel, dc regulator, batteries.
how to stop charging when the batteries are completly loaded in order to avoid overload ?
I saw that zener diode could do that (stop charging).
Has someone an electronic scheme available to,do so?
Thanks
Regards
