cyclone 24v 3000watt bldc controller max voltage? modify max voltage?

[fabieville]

What is the max voltage i can feed through the 24v cyclone bldc 3000watt controller?

I am planning to upgrade my battery bank to 48v or maybe 60v to power my cyclone 24v-72v 3000watt motor. And i am wondering how much voltage the 24v controller can handle?
Is there anyway in which i could modify the controller so that it can accept up to 60v or more by changing the capacitors etc.....?

Because to buy the bigger controller that can accept 36v-72v is quite expensive.

Any help would be greatly appreciated. I anxiously await ur responses. Thank u.

Where did you buy the motor? Do you have a pic of the controller? Does it have bluetooth?
I don't know of any controller sold with cyclones that is only 24v.

I bought it from a turbobikekit.com
It does not come with bluetooth. Below is a pic of it and the motor.

I have push up to about 38v so far throught it without any issues. I am wondering a far it can go?

On the website they sold them in various voltage range. This one is rated for 24v 40A constant 100amp peak.

This one is just a regular non programmable one.

You will have to open it up to know for sure. Unscrew the far end where no wires come out. Look in with a flashlight if you can read the labels of some capacitors. If it says 90v you are good to 72v. If it says 60v you are good to 52v batteries.

so is just the caps i would have to change?
what about the fets? should those change too?
what about the onboard voltage regulator do that has to change too or how can i get around it?

if I have to change the fets which fet number would be best to use that can handle up to either 75v or even 90v?

I am aiming for a 60v ebike setup but I will settle with a 48v if I can't push the controller too far.


Is it possible to power the motor with a high voltage and the controller still seeing the correct 24v voltage or the built in supply voltage regulator seeing the correct voltage?

You aren't changing anything now. That is a different discussion. You want to check the caps because if the caps are high voltage the fets are too probably because higher voltage caps are more expensive. So usually the two go togeather.

what about the built in voltage regulator. Would that have to change?

No idea, but caps good = everything else good enough to risk it.

i just check and the caps are rated at 80v and the fets (SI-TECH/S10H16R) are rated at 100v so that means i can try a 48v to 60v battery on it right?

With the cap voltage at 80v would it be safe to assume then that this controller is not 24v only but infact 24v-72v just like what the motor is rated for?

or probably it is rated for 24v-60v? seeing that 72v is kinda close to the 80v max and charging a 72v battery would carry the full charge voltage pass 80v.

The 72v nominal (84v max) controllers usually have 90v caps.
