ok correction time, in an attempt to document the 36v output with no +ve voltage suppled to the bms, i pulled the plug with the led meter attached and it died instantly?? I have no clue? I swear i measured 36-37v on the battery output without the bms multiwire plugged in MORE THAN ONCE as it...

so the 2 x solder pads next to the sw label on the pcb have no effect on battery output voltage if connected to a latching switch or shorted.. I have validated the switch breaks and maintains continuity.. pictures attached with the button depressed and not, output voltage remains constant.. 1...

Opening this up was uncomfortable... Looks like a pair of convenient solder pads sat next to the 'SW' label on the pcb (bottom left side of pictured pcb) However i still balk at shorting those pads out and testing the battery output terminals.. ----hand holding required.. ignore what...

?? did your battery have a backlight and perhaps brake light fitted too? If so perhaps the 3 thin guage wires just supply the lighting voltage to the now gone lights? and just the battery connections are needed (thick red/black wires)

cheers i have some of that and some thinner 2"wide pvc tape but was concerned it may add too much 'girth' and cause issues re-clamping the lid to the base with its already damaged tongue and groove lips and one threaded screwhole.. worry averted cheers

someone needs to look up the word 'HUGE' in a dictionary.. It is a nice and stealthy kit tho..

The world is out to get me and stop this bike from getting sorted.. 2 x household devices went 'poof' and released the magic smoke.. tefal will pick up the airfryer for a fix (only 18mnths old..) phew, but the TV is dead.. 1/2 the screen is just a gray block.. hmmm thats a subject for youtube...

Hope the auction price was a steal.. Lets put the refit job into perspective, conversion of a 'virgin' donor bike is an afternoon job within reach of anyone capable of changing a tyre. And with the motor wheel already installed in your bike thats 50% + done before you start. The rest of the...

Cheers @saneagle, i will probably need a few read throughs before it starts to gel, ive lurked on the peripheries of rc and model engineering communities a little not delving deeper than admiration for the most part tho. so other the odd servo/stepper motor ebiking is my first real exposure to...

Im still confused about hub motor max rpm and the impact of running a 36v motor with a 48v battery/controller? Is the motor max rpm a constant regardless of the input voltage or does it also increase inline with the voltage supplied? This seems like a good place to ask ;) Cheers.. btw links...

key aspects of your controller/display combo is the 14a peak power rating and the led/dumb display unable to give a dynamic response. which indicate configuration changes are difficult to make without a dynamic display (LCD etc) and any unrestricted top speed would be limited by the 14a limit...

Hi Alan, welcome along.. Trikes can be anything from a fixed frame 3 wheeler thats a sod to corner beyond 6mph to a high spec recumbent with enough engineering to provide for cornering at speeds more inline with e-bikes Or are you interested in an electric tuktuk type vehicle for cargo...

There are hundreds if not thousands of ebikes out there and google isn't very forthcoming with details on your bike.. so pictures of the display battery and controller would help identify the systems used.

With a known good battery and a kt display already purchased spending a further circa £50 on a suitable kt controller and cadence based pas sensor (£5-6) is probably your quickest route to success, its just blind luck your current controller shares the same ground, power and speed signal wires...

Yeah, confirm your controller is also KT otherwise you could be chasing your tail indefinitely, KT is short for Ketung iirc, many controllers are silver boxes, but KT controllers also come in a down the tube option or in the battery sled (hailong batteries) types too.. If difficult to unbury...

Found a lovely SS waterproof switch but its a momentary switch ;( looks like ebay is where i am off to.

Cheers @harrys, thats why im asking any switches i have rated for DC current are both quite beefy (large) and not waterproof at all.. @saneagle.. -- say what?? Perhaps its worth opening up the shrinkwrap for a look at the bms pcb.. Even if i find well labelled solder pads however i think i...

DOMINOS and not the pizza one thing lading onto another.. I got the whole bike back to test the wheel connected to power, and upside down the battery is not making a good connection.. and as this battery has no on/off switch, trying to juggle the battery against gravity into place just...

Hang around in here and you will learn Saneagle is ALLWAYS right when it comes to ebikes.. But since google gave me so many 90 sec vids on how to de-reg (lift the speed limit) of your bike.... -many bikes feature code lock outs, if not used however?? A teen prank without thought of...

I dont know your bike or its operation, but no mention above of any configuration settings or checking there of. even with my eu/uk 'hobbled' controller f/w i have access to a few controller settings, Could a display button/controller fumble or ?? have resulted in something getting set in...
