Ezee Sprint controller info please

[MalcolmW]

Can anyone help me find the voltage range for the 36v controller fitted to the Ezee Sprint (four years old). I need to know the maximum permitted voltage and the cut off voltage. My nmhi carry on but they are getting a bit sad and I want to explore the options.

The cutoff voltage is 31.5 volts, the maximum voltage permitted is nominally 44 volts, but varying plus or minus a half volt in eZee controllers.

No damage is done by over-volting, the controller LED merely cuts out after first lighting, then gives a rapid 7 flash signal and refuses to run the motor.

Thanks flecc. I am assuming that the motor is happy up to 44 volts.

Yes, no problem, the motor should be happy with more, but eZee have always stuck to their tightly defined controller.

Just a little update here. The latest spec eZee controllers I am supplying are suitable for batteries up to and including 48V.

That's good to hear that John, the old spec was a bit tight for some fully charged battery options that are around today
