hello friends..
DC Jack is ok.. 20V entering the first MOSFET,, but nothing out..
using my power jack to inject 20V after the first MOSFET, nothing out.
but after inject 20V after the second FOSFET, the board worked,,
when i remove the first MOSFET,, and inject 20V at the input of second MOSFET, the board worked,,
try to change the first MOSFET,, but nothing changed.
so i try to jumber the first MOSFET,, all things worked .. but the board can't charge the battery.
i test the battery,, and its working very good..
any suggestions?...
