Are you seeing 3.8volts per cell (all cells match?).

Do you have another battery you can try?

I have a venom charger all cells show 3.8 accept for one of them it shows 3.7

I am guessing your Battery is not so good.

After Low Voltage Cutoff (LVC) your batteries should measure around 3.6 volts per cell. If your battery is not healthy it will sag more under load and trip LVC showing a higher resting voltage after cutoff.

If one cell is going bad that can cause this too, the voltage of the bad cell will drop rapidly causing cutoff.

I would try another battery.

I don't think that ESC supports 2S.
