I am selling my old Curtis 1239-8501 AC Motor Controller 144V 550A controller. I just received this back after having all the fets replaced and a couple of other bits fixed on it. It had overheated and failed. It was away for so long because of Covid that I have bought another so this is...

Pmed... I'm interested in the lot

I have the batteries and lyen controller up and running Its a bit of a birdnest but that's about as tidy as I can get it. The batteries are 16s1p 10c 10ah and I tell you what it goes like stink. But I have to check the various hall sensor and phase cable configurations to get the best...

Right I have waved a meter at it and r-soldered the big - wite to the BMS board and put a new big - wire to the main connector from the BMS. SO all I need now is the heatshrink to fit it all together.

The BMS has B- and P- and no B+. I assume the battery packs first Balancing wire is connected to the main positive power wire, therefore this will be connected to the load/charger +. I do have instructions with the BMS, but its written in Chinglish. I am confident I understand it all well...

Thanks Guys, My balancing plug to the BMS has 16 wires. Also you have confirmed what my limited knowledge was telling me. If you see a bright flash on the horizon, I have done something wrong later today......

Oh yes of course, Sorry, I forgot about that! Intelligent charger.

But you said you had custom Y and balancing cables? I have the Y, but assumed the balancing cables connected to a BMS? Thats a nice new project!

Allex, what did you do with the BMS on your batteries?

My battery is about ready to go in.....

Hi All, I am connecting 4x 4S batteries in series to make 16S. I have a 16S BMS I am connecting up and have a couple of questions. Bear with me.... The balancing wires on the batteries have 5 wires as you would expect and I assume are wired up P-NP-NP-NP-N to the 4 cells. To connect the 4...

I contacted UUmotor and discussed it with them.The contact is: "Tony Zhang" <sales@uumotor.com> Its this one I think: https://www.uumotor.com/12-inch-500w-gearless-hub-motor-direct-drive-regen-braking.html But the controller I have doesnt support regen, and Itold them I wanted 48V 800W. I...

I spotted I had damaged the cable coming out of the hub motor along the way, so whn I fit the Lyen controller on order I will have to do some soldering and heat shrinking, but insulating tape will do for now, how annoying. But also the new deck turned up so thats fitted now too and you can see...

OK, so this weekend I cleaned it up and fitted my 48V 800W hub motor and matching front wheel and controller purchased from Tony at uumotor. To be honest the controller could have done with some setting up instructions. But Tony set me straight. The controller has reverse, cruise control (wired...

Hi All, I am upgrading my powerboard with a hub motor and matching front wheel. I have recieved it and gone to swap my discs over and the damned thing dosnt fit. So I went to the local Bike store and neither do their discs. Does anyone know if there is a special ID and hole pitch needed for hub...
