https://a.co/d/0ilO0vTu I recommend trying thia voltage controller. I have tested it personally for about 2yrs now on my son's mini Amazon banshee. I run a 20v dewalt battery, with dual high rpm 12v motors and haven't had any issues yet. The knob on the side allows u to control the voltage anywhere from 20v down to like 10v, so u can speed it up or slow it down. The digital screen displays the current voltage being run.
