Need to make a low voltage dropout module to protect the battery from going to low when driving a load.
The charging module was allowing the voltage to go to low (about 2.5vdc) which i did not want.
A pushbutton start the voltage to the 3.7 to 5v module.
The P mosfet turns off when the battery voltage drop below the vdrop set voltage(3.4vdc) which in this case is set by voltage divider using the 5v out tap as a reference.
