April 28, 20214 yr Hi can any one help? I have a Batribike trike 20 and need a new controller on/off battery level/assist level unit. Many thanks Regards Paul.
April 28, 20214 yr You can use any of the regular standard Chinese controllers. Some are better that others. the more you pay, the more you get. Are you happy with soldering and wiring? It might be worth telling us about what's wrong with your bike and how it started unless you're certain that it's the controller that's faulty and not the control panel.

April 29, 20214 yr Author Hi can any one help? I have a Batribike trike 20 and need a new controller on/off battery level/assist level unit. Many thanks Regards Paul. Hi again thanks for your reply,yes happy to do soldering no problem. Yes I am sure it’s the control panel that’s at fault. Did not know if spares for this trike were still available, but sent email to Batribike and they replied saying No Can you recommend any control panel ? Many thanks again. Regards Paul.
April 29, 20214 yr It would be best if you show a picture of it and a picture of the connector. In the meantime, you can restore basic function of your bike by disconnecting the control panel and bridging the red and blue wires in the connector with a paper clip or something like that. If your controller and motor ar OK, you will get level 1 pedal assist and normal throttle operation (if you have one). Make sure that it's only the red and blue wires you bridge and not anything else.
April 29, 20214 yr The LED looks like many others led880/890 so may or may not work. What is best is if you can show a pick of the controller box, follow the motor wire or the LED wire to the box and take a pic of the label for us. We then may be able to identify better.

April 29, 20214 yr I was hoping it would be a 4-wire one because 5-wire ones can be analogue or digital. OK, we're going to have to find out. There are two ways. either way you have to follow the green and yellow wires to where they're soldered either in the controller or in the control panel. As the the panel is unserviceable, I'd go there . You need to open it up. if you're lucky, it'll have screws otherwise it'll be glued and need to be cut open. If screwed, they normally have some sealant between the two halfs, so you need a bit of leverage to open it agter the screws are out. Once open, you can see where the wires are soldered, and you might be able to see an obvious fault, like a wire off or water damage. What you need is the markings on the pcb where the wires are soldered. Tx and Rx means digital. Anything else means analogue. As there is no light switch, it's most likely digital, but we need to be sure before telling you which one to spend your money on. That looks like a KT label grinning at us from under the red Batribike one, and the engraved serial number also looks typical KT. I don't think I've seen a KT on a mainstream OEM bike before. If it's not too much trouble, see if you can steam off the red label to see what's on the one underneath. I'm pretty sure that it's a Batribike-branded KT 880 LED display, but you still should check. if it is, there are lots of options for replacement. http://www.szktdz.com/en/news_show.php?article_id=336 Edited April 29, 20214 yr by vfr400
April 29, 20214 yr Hi again is this picture any help? As both wires are soldered next to each other and they both go directly to adjacent pins on the CPU. I'm going to stick my neck out and say that they're Tx and Rx and it's a digital control panel. See if you can expose that label before making a final decision on what replacement to get. It's probably had water in it judging by the rust on the two switche, though they normally look a lot worse than that. Is there any indication on the back side of the pcb. what are the markings on the edge of the pcb after it says "KT -" Edited April 29, 20214 yr by vfr400
April 29, 20214 yr Author Hi again. Is the label your talking about on the controller under the pinkish label?
April 29, 20214 yr There you go: LED 880. https://www.ebay.co.uk/itm/203301227208?mkevt=1&mkcid=1&mkrid=710-53481-19255-0&campid=5338624526&toolid=10001&customid=4378a42a9d3f94fe9a40095e93eec249 I was thinking that it might be worth upgrading to an LCD, but for that you need a speed sensor. If you think you like that idea, show all the connectors on your controller so that I can see each one and the colours of the wires to see if there's an input for the speed sensor.
April 29, 20214 yr Author Hi again. More pictures also lights were controlled from panel I think if you kept pressing on/off button the lights came on? As you can see in one picture rear light is wired into controller.
April 29, 20214 yr Author Thinking ab the lights perhaps the 790 model which has a separate light button?
May 2, 20214 yr Author Hi again. Sorry for delay please find poor picture as bottom label was starting destroy hope you can see enough
