3.7V Li-Ion battery isolation at deep discharge “

Hello,

I want to isolate battery input at its deep discharge voltage. I have 3.7V Li-Ion single cell battery and it’s deep discharge voltage is 3V. I want to disconnect the load from battery automatically when does it reach at deep discharge to avoid over draining and increase the life cycle of battery.

So could anyone recommend me any device like relay , switches or something else which full fill my requirement.

Thanks in Advance !!!
