I just built this circuit, with the intent to use it as a low-voltage cut-off switch for a single li-ion cell. It works great, but once it's triggered it needs about 7 volts to turn back on, so I guess it was intended for a 2s pack at least.

I was wondering whether using a Mosfet with a lower gate threshold voltage would be sufficient to reduce those 7 volts to just under 4 volts? The Mosfet I'm using is STP75NF75.
