I attached a version with the gate driven from the Arduino pin with a 150ohm resistor.
A downside is that the MOSFET will be ON if the Arduino is powered down
And the LiPo is still connected.
I intend to always keep power on the Arduino and Load, but just put the Arduino in sleep mode. Is there any problems with doing it this way? Do i need to add other components to make it safer?
Thanks
