About the voltage drop OD spoke about.
Maybe you could try a capacitor on the esc to smooth out the voltage ripple.
The capacitor should be a 'High frequency Low impedance' version with a working voltage greater than 10v and a capacitance of about 2200uF.
You can buy it at your local electronics store.
In case you don't know how to connect it, the leg nearest the grey stripe is the cathode and should be soldered to the - from the battery, the other leg should be soldered to the + from the battery.
I have no experience with Keyence esc's so I don't know if it works, but it should work with every esc. And it's worth to try since they are so cheap.
