Best errr on the side of caution if using a lipo unless you can find out 100% it has cutoff,as soon as you see even the slightest drop in performance stop!, back when quite a few of us we using lipo with brushed ESC's it was quite easy to go for to long. Thomas discharged a couple of lipos to low and a lipo charger will not charge them again.there is a trick to get them back....but it's a bit spicey
