This kit is "for" the Quad 500 from razor that comes stock as a 36volt quad , will NOT work with the "Stock" dirt 24v quads unless you put 3 batteries in series as this works in 36volt only, if your not sure look at your existing charger it should say 36volt. The scooter controller comes ready to plug into your 36v sytem so you must have your 3 batteries in series already.

 If you have the quad that already has stock reverse you MUST purchase the reverse ad on as explained below and include a note that you have the reverse style quad so we adjust the connections to plug into the factory foward and reverse switch.
