My 20S i run in the 70 to 80V range. With 2 seater, i can go 35 miles. I was thinking of adding more modules but for my purposes it is unnecessary. I have an SUV and 2 motorcycles. The GEM is cheapest to operate because I have rooftop solar.

A GEM OEM buzzer goes off if i go low V but the GEM doesn’t stop. I added a switch to turn off the buzzer.

Mine doesn’t stop, but if I shut off the key, it won’t restart. That’s where the spoof by-pass comes in. 😉

Don’t know about you, but I think that is an advantage. Ie. not starting with low battery.  
Keeps you on your toes!  
Stock Gem will also fail to start under 68 volts, but there is no fix. Tow or charge.
