Im wondering if I instal a 60v controller on my 48 volt system will I get an increase in speed at all or is it just a waste of money the specs for my scooter are below v
Motor
Type Lube injection gear reduction BLDC motor
Rated Voltage 48V
Specified Output 500w
Highest Idle RPM 400rpm
Fixed torque/corresponding rotational speed- 22Nm/284rpm
Maximum torque/corresponding rotational speed- 64Nm/25rpm
Idle operation electric current 1.8A
Operating current 12A
Overload Protection 600V Circuit Breaker
Controller
Type Computer controlled switching and power regulation
Rated power 750W
Power Supply Unit
Batteries 48V/20Ah (4 x 12v/20AH Valve Regulated Absorbed Glass Mat)
Weight 62 lb
This is basically the exact same motor I have on my Luyuan Condor E-Bike from Mobility Unlimited in Toronto. Putting a 60 volt controller in a 48v system will do absolutly nothing till you increase the battery voltage. Also if your E-Bike has a DC to DC converter you may have to replace that with another unit that can handle the higher voltage.
Thanks,

My recommendation based on 100's of applications is to do the following on your ride.
1) Add a 72v hi-amp controller
2) Replace 48v DC converter with 75v
3) Add a 16v Li-ion battery pac to raise your voltage to 64v
4) Use your 60v charger
