On off switch

Need a circuit to cut power off totally. This is for a battery powered headset Bluetooth. Left voltage generator is battery. Right one is 5v usb to recharge battery. I need to know if it's OK or not to use a mosfet this way. I can cut the power off from battery. But in the other direction, current pass is always allowed. (when charging). 1R resistor is 500mA simulated polyswitch. Bulb is simulated circuit to supply. Need this particular circuit because I would use internal battery charger of bk8000l. Sorry for bad English.

Thanks for the idea. An other restrain is size. The system has to fit a motorcycle helmet with the rest of electronics. So... No relay
