Ok, the voltages on one are all around 12v and on the other two are around 13v and one is around 11v. the dash lights up ok and says full power on one scooter and the other , ? I forgot to check it but i'll check it later. the controller is CT-660B9. what if I bypassed the controller and hooked the batteries directly to the motor just to test it out? Is that a bad idea? -Thanks

@BrutusJones Yep, you can connect the motor right to the batteries. Just make sure you lift up the wheel or you will be chasing it :-)

Also make sure your brake switch is not stuck on, because that will disable the motor too.

I bought two scooters just like the one in your video. Can you tell me how to check if my controller is bad or not? Also , both chargers are supposed to light up red at first but they both light up green as if the batteries are fully charged but they won't run. ? ?

Thanks in advance for any tips.

@BrutusJones The controllers were pretty unreliable in these from what I understand. That's why I ended up installing the new one.

How many volts do you have on your batteries when they are charged? The scooter won't move if the charger is connected, or if either switch is turned off. Does the battery gauge on the dash light up?

If the batteries are original, they are likely no good.

Let me know your battery voltage, and we can go from there.

I have a 36v x 360 electric motor scooter and im thinking about adding a 1000watt motor with a 36v 1000watt controller would that make my scooter go faster ???

[Maxxarcade]

@MrDjMon4Lif3 If you can find a spot to mount the motor, then yes, it will be faster. Especially if you put a bigger sprocket on the motor. You will have lower battery life though.

@fishinman69 You could use a 48v controller and battery pack for more speed, but your motor will not last as long :-)

Do not try to use more than 36v of batteries on a 36v controller, it will probably be damaged. A set of 3 fully charged batteries in series typically measures about 38 volts. The 36v controller can probably handle 41v or so maximum.

i have a stealth 1000 and it has a 36v controller. If i put a 48v controller and of course 48v battery, will I gain anymore speed? How do these controller work in handling higher voltage than specified? Will a 36v controller only supply 36v to the motor?

[Maxxarcade]

@MaxSachs That would not work the same in this case. Small capacitors are usually used across switch contacts to reduce wear from arcing. Adding a capacitor to the input line of the controller would only increase the inrush current, and the arc.

@Maxxarcade

Just had an idea, all of my mopeds employ capacitors to regulate spark and rectifiers to regulate voltage and current. What if I were to place a 50A inline fuse and a high rating capacitor between the battery and the controller, the fuse to protect the battery and the capacitor to protect the controller. On a moped this serves to maintain spark and to protect lights from blowing.
