Low Voltage Cutoff Circuit
 

I just recently started building my own mosfet units based off of the plans floating around the net. They work great, so I've gotten to thinking about building a voltage cutoff circuit.

I want to keep my batteries in top condition and making sure they cant exhaust them selves past a safe threshold would be a pretty solid step in the direction.

So my question to you guys is, have you ever built a low voltage cut off circuit and if so could you share your plans? I'd love to find a way to make one which could switch between 7.4 volt and 11.1 volt lipo batteries.

Take it easy.

There are lipo protection circuit module or board out there, ready to install, but most 2S or 3S PCM/PCB do not support the high current on some airsoft guns.
