hi load result 3.3v per cell on 2S lipo.

this is because when you running the hi load, such Mod motor or low FDR
the Hobbywing Firmware cutoff you set on 6.7v will result
cut off when it reach about 3.15v per cell.

and if you run Mod or low FDR, the Draw of your Lipo is Higher, resulting, to Drop below 3.3V ex: 3.1v/cell,

now because you run Stock, and Higher FDR, where result Lower Draw of your Lipo, the Lipo Voltage is about stable, and only cut off if it really reach,
3.15v per cell.
