The Expert+ doesnt allow adjustment for the cutoff voltage either. Just settings for cell count.

Does anyone know what the actual cut off voltage per cell is for the MGMs? I assumed it was 3.0V/cell, but it seems to be a bit higher than that. I run some lower end lipos for bashing and it seems to be very sensitive on the LVC. I wasnt sure what was happening, but under hard acceleration it want to trip the LVC. When I go back to neutral it resets and I can keep running so it appears to be the LVC. But when I checked it with an eagletree data recorder its not hitting the 3.0V/cell mark and it is triggering the lvc. It seems to be tripping at around 3.15v/cell. Id really like to be able to adjust the cut off voltage as well, but I dont think its possible. Setting the ESC to race mode eliminates the cutting out problem, but also disables the LVC.

I can also eliminate the problem by setting the motor spool up timing higher, but that limits the acceleration, and therefore reducing the current draw. Also, my high end lipos have no problem and they never dip

Just wondering if anyone else has seen this same thing.

BTW: I see the same thing on both of my MGMs (16016 -new one and 16024 - old one)
