Max voltage on Cyclone 500w kit

[disndat]

Does anybody know of the maximum voltage you can put through the 500 watt cyclone kit(the one with the built in controller)?Has anyone run 48 volts without blowing it?Please let me know.

Thanks

48v will blow it up !!

the 24v controller will work with A123 10 cells in series and that's 33v.. but a fully charged 48v hot off the charger would be something like 56v = Pouf..

Hey Gaston I've actually run it at 36 volts(11 A123s in series)and no smoke so I was just wondering how far I could push it.Have you actually blown one up?

The caps inside the internal 24-volt controller are rated 35 volts. You might get away with running 36 (or 33) volts for a while, but doing so won't improve its reliability. If you want to run 36 volts, better to buy the "900 watt" kit with the external controller that is made for 36 volts.

Cyclone Taiwan claims that the raw motor w/o internal controller (same motor as in 500-watt kit) is good for up to 60 volts, 50 Amps, not both at the same time. I've put 2400 watts into this motor using the 48-volt Headline controller for about 30 seconds on the bench, and while the bulky, well heat-sinked controller chassis gets moderately warm the motor gets too hot to touch for longer than a second. The thermal breaker did not trip. I haven't yet tested reliability on the road with power IN above 900 watts.

Hey MrBill thanks for your reply.I already have the kit and I am working on my own kit with different parts so I am not in the market for another cyclone kit.Do you know if the stock caps can be upgraded?I am not too worried if I butcher the kit-it was just an experiment on using gears-its actually the elation kit from australia.I have not opened the motor/controller up so I dont know if there is space for a little bit bigger caps.If I could run this kit at max 40 volts I think I would keep it otherwise I will use the bike for something else.

If you don't mind losing the warranty you can try anything you like. You'd have to find some small metal can (electrolytic?) caps that fit in the same space. Space it tight on the internal controller. Whatever you do make sure that nothing rises above the top of the Hall sensor clip. Here is a photo tour, in case you missed it when Rick Kosiorek posted them earlier.

What is the max current the 500w motor controller can handle and what does the controller do when you exceed the limit?

I've been using a 24v20aH ping battery with the motor without any problems. The ping battery has a limit of ~30A

I just recieved a 24v20aH Headway battery pack with a max current of 60A, and I'm having problems with the battery cutting out. I don't think its due to the motor controller, but it may due to the headway battery BMS. When I gradually add brake load on the motor, the headway battery cuts out at ~25A, whereas the motor stalls at ~30A using the ping battery.

i have seen 40A peaks on the Cycle Analyst using my 500W Cyclone.

Taiwan cyclone says if light goes out its BMS if it stays on its controller(when motor cuts) with this happened with me then controller ruined it was loose terminal that caused bms cut out .
