24V to 36V ?

[Seanoge]

Hello, I'm new to Ebikes. My wife has had a Freego for 18monthe with little problems. Sometimes I was allowed to use it. Saw an ex-demo Cyclamatic GTE for salefor £380.- delivered. That was 4 months ago. Great bike for the money but had a few problems and it has been returned for repair. Now its back with me and needed a new throttle which I have just fitted. The people at SportsHQ where I bought have been very helpful. There is a big difference to my wife's 36v. Freego and my 24V. especially when going up hills. I was wondering if it would work with a 36v. battery. The throttle has a 24v. sticker on it
Also I've noticed that the connections in the 24v. battery are rusted. Any way of cleaning these or does it matter?

D8veh will probably disagree with me but this is my tupence worth.

Cleaning the battery contacts is a good idea. And perhaps coating them with petroleum jelly afterwards will not hurt.

If you put a 36v battery in then either it will blow the electronics in the controller or not , that will depend on the rating of the components originally used. Even if it does not it will be putting them under stress and with a probable reduction in lifetime.
The 36v battery will not destroy the motor. It will drive more current through it, rotate it faster, ( depending on the technology used) and create more torque. Some of the additional voltage and current will create more heat in the windings of the motor, and is basically wasted energy. The additional torque will increase wear on any cogs within the motor. Do not assume that you will get 36/24 more range from the same AmpHrs

I think putting a 36v battery on a 24v cyxlomatic is fairly tried and tested without issue

Yes there are risks, mostly to the controller, but these are very cheap to replace. And you could do so with a 36v controller

I have overvolted plenty of 36v motors, I have blown the odd controller but usually when really taking it too far (like running a 36v controller at 54v )

Once upon a time I ran a 36v hub with a 48v controller at 52v for ages without issue.

That's right. I've never experienced any problems running 24v controllers and motors at 36v. There's some advantages of getting a 36v controller. They don't cost much, and it's a good chance to update the Cyclamatic's crappy control system to modern one.

Yes the sine wave S06 fits the foldaway space and is all ready when I have the battery recelled to 36 volt.
