F2 Issue - Slow down to 18MPH when battery is less than 60% battery

[Jinmcx]

Stock firmware does this as well but I was hoping NGFW would resolve. Not issue if it's an issue perhaps a recommendation fix.

At high 80% + battery can reach 22-23MPH but once it goes down 60% it difficult to maintain 18mph.
