Looking at the other topics I pulled together the following parts for upgrading a Razor Dirt Quad from 24 volt to 36 volt. Can you confirm if these are the correct parts or if their something that would work better.
MOT-36800B 36 Volt 800 Watt motor
SPD-36800B 36 Volt 800 Watt controller
THR-86 twist throttle with 36 Volt battery meter
