What’s the best cutoff voltage for a Lipo battery

I run two 6s 12000mah turnigy lipos. I was riding tonight, everything was going great, and then there was a loss in power. I checked the VESC tool app, and my voltage had dropped from 44 volts to 22ish volts.

I checked my battery box. One of the lipos had some swelling. I used the extra batteries in my packpack to ride the remaining 1/4 mile home.

I checked both with a voltmeter, and the good lipo is at 19v, while the puffed lipo is at 18v.

I got these lipos at the same time and they have the same cycles on them. What could have caused the puffing and uneven discharge? I wasn’t really running them that hard.

I have another set of Tattu 12000mah 6s lipos that I can run instead of the Turnigy’s, but I don’t want the same thing to happen to them.

This is what happens when you run them too low.

Try this

12S lipo (50.4V charge)
cutoff start 45.24V
cutoff end 44.52V
