LI Po Voltage cut off
I want to run a GWS 370 MOTOR (Brushed) in an old Crazy Max. I want to use a 7.4 volt Li Po battery for power. How do I insure that I don't run the battery down below 3 volts per cell (6 volts for the 2 cell 7.4 voly battery)? I have a 30 Amp speed control (overkill I think) but see no provision for voltage cut off. Looked around the various web sites and didn't see anything which talks about it.
Thanks.
Dave
