Well just been back to the bike, and even with the error 30 on screen, it still works, the PAS works, motor runs. Pulled and reseated all plugs and all look good, no bent pins. Will just leave it to customer to see if they want to risk £180 or so on new rack and battery. Can’t even see water...

That is great, thanks On phone now will read up more tonight on big screen

Hah hah ! Yes sounds about right. I did not ask

40 volt is my own battery from another random ‘36 volt’ e-bike battery A hot off charge battery for this bike would be 41.8 -42 volts… same as any ‘nominal’ 36 volt battery. Original charger was not lost and that is 42 volt. I could perhaps try to rig up a 9 series pack of lower voltage …...

Just been presented with a Viking Freedom bike with a KD58C display/ control unit Owner lost battery and a cycle shop tried to fit new one, but could not get it to work. I put 40 volts up it and neither could I get it to work, until I tried long press on display unit button. It now does work...

You can reference the letters ABC etc in the photos below to the text in the pdf's in my previous post.

OK, so PCB, yes it was DC-DC convertor, and it did not have power on it, because it only gets power on it when the lights are turned on from the handle bar switch, so yes it is a voltage dropper for the headlights..a red herring as to why the bike was not working. The brake that was not...

You did well to read that ! I went back down the shed last night and tried to read with magnifier and take more photos.. Yes, think you got it During the night I had two thoughts.... 1) Is the PCB maybe the voltage reducer for the built in headlight system, and therefore normally un-powered...

No , charger connects just to the three central triangle of pins. One pin goes via thermistor to ground, one direct to ground, and the third positive via a £ amp fuse. The PCB red wires connect to two pins, opposite each other and go to controller. Unfortunately can’t get the socket out of...

cells were identical physical size 18660, 4.5 Ah NiMh, (Sanyo SDK I think the new ones are. Have now attached photos here. My work is emergency ambulance stuff, so I had to just run earlier when I started this post. I am now in Oxford waiting now for medical team to get back. I will...

just re packed a bottle battery and fitted a new motor to an old Cytronex Cannondale bike Battery is NiMh about 3.6Ah 30s1p 18660 sized cells Motor was rusted up , but did run ..but noisy and often slipped as the internals were ..knackered Fixed that but battery was just about dead..some dead...

well, yes, goes without saying , always replace all cells this pack is AA NiMh cells in a waterbottle pack. Not going bigger, just exact physical size for size replacement...if needed... horrid multi pin at the top of the bottle connector. and difficult to get a view to get a pin out...but...

Just been down to workshop to check Yes charger is labelled as 36 volt 2.5 amp Pack up at 40 volts when charged...but not sure if that is full or not. Pack has sat for a year or more and went very low. Also one of the nickel strips had popped off the bottom of the pack. have tabbed welded it...

A few sites I have seen say NiMh peak at 1.4 to 1.6, and the OEM charger is 50 volt open circuit I already have some 12s BMS’s kicking about, so that OK Controller is easy to access, which is goid Yes, definitely quoted as a 36 volt system..which is why the high charger voltage surprised me...

Ok Thanks Issue with e-mail was due to their server not liking my own personal E-mail domain , until they sent me a message from a msg I sent via their web form, which finally worked. Their sending to me would have auto added my e-mail domain to a whitelist ( I guess) and allowed my subsequent...
