The controller has a small Thing attached to the blue wires. I imagine it's some sort of resistor adjustable with a screwdriver. Something that apparently enables the speed to be adjusted, I was told when I purchased this is is at maximum. I tested the bike with a gps device to check the speed...

Excellent, i will check this out, at the bare minimum this will allow me to go a wee bit faster. Thanks again.

That would make sense with what i was told about the controller, the guy i bought it from mentioned something about 50v. It seems i need to probably put up with this or change the whole lot to get something a bit faster. Thanks for your help.

Here are the motor pics. I think the guy i bought it from opened it up and said it could take 50v, but i guess i will need to open it up and check. What am i looking for exactly inside.

I see from one of the other posts this is going to shortern the lifespan of the motor, but i don't mind about that since its only a few miles per day. Alternately if someone can suggest a better cheap hub motor i can just plug in and run at 36v and not have to mess about with trying to push this...

I recently purchased this lot used from someone: 250W bafang rear hub motor 36V controller (pictured) 36V Nimh battery (from 50 cycles) 9Ah I had a cyclone motor and the chain was causing me issues by constantly jamming so i have this little lot attached to my bike now. I like the acceleration...

The replacement should be the new version, i had a replacement about 2 weeks ago when the first one just stopped working and didn't do anything with the cells, they all became unbalanced. Here is a picture of the BMS, sorry about the quality it was taken with a camera phone, pretty well broken...

I don't want to hijack this thread, but i was looking at these controllers as well for my cyclone motor. I assume they will work with that type of motor without any issues.

Wow quite a bit more than Li Ping, $46 + shipping directly from him, shame it takes so long.

I need to get a new one of these since my one cooked itself this week. Its going to take weeks to get one from China, does anyone know where i can get a replacement item from in europe or the US? Its the v2.5 48v 20amp battery that i am using. I have a spare one that i think may be broken, but...

Sorry, Maybe i should explain, in the UK we use fuses in the plugs (the plug being the part that goes into the wall). In the US you don't use these since there is no earth so i should have explained beforehand. Here is a picture for you http://en.wikipedia.org/wiki/File:Bs1363-plug.jpg The fuse...

I tested the battery pack and thats showing 48.5v so thats good at least. Thats a reading from the input and output wires. One strange thing though. If i plug a new power lead in, the charger pops again and blows the fuse in the plug. On the output side i have noticed a small dent/cut in the...

I have hit 52v on my controller, but since my turnigy meter isn't near my eyes i can't see if its hitting that limit and then its overheating. I usually leave it on the middle sprocket on the rear and anything other than speed, since i pedal off the lights anyway so hopefully the motor isn't too...

Since i had to leave it all at work, i need to take my multimeter in to check some of the components. I might see if i can take my camera as well and get some better snaps if its of any use to anyone in the future.

its hard if not impossible to see but they both are individual and go into the board. around the solder on the board on the right side of the component, its charred looking. you can see some residual burn on the shell of the component on the far right. I can't see any caps with bulging tops or...
