Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

I think its CA 2.4 pasc2003 I would love to know what programming you use on it? I was told the motor can only handle 90amp peak? its a 4kw motor but can do 7kw peak. QS motors seem to be overbuilt, I feel like my settings are underpowering it. I reckon that when I tried the max setting 100% 70% and...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

I've had advice from many different sources regarding the kelly programming. QS say stock programming doesn't need changing but my CA said otherwise. I think my first ride I had it at 70% and 100% and something cut out, my circuit braker didn't I was thinking it was the battery CA showed about 135am...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

Sorry for the late update- I have pretty much finished this bike about 1 month ago. Still need to add some paint to the side metal panels and re-position the revers switch (so my keys dont bang against it) For some reason the modular dash battery lights and temp sensor near the wheel have shat thems...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

So I finally did the rest of the annoying paneling. This is truly some frankenstein stuff, some tin some plastic. Also took apart the modular battery to change the alarm settings Hooked up a main plug for the alarm outputs to dashboard and labelled each cell stack 3.5v low voltage 4.1v high voltage ...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

Yeah I've seen this. I needed a solution that was easily removable and easy so i could carry and charge battery inside apartment. Plus I feel like a modular battery made from 18650's would be easier to repair

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

Okay I haven't posted in a while very sorry about that. I have been gradually building the bike What I've done since last post - Figured out the shunt and amps reading for CA. I won't know real readings until I test ride it (put under real load) - I thought I needed a solid state relay in order to a...

Re: Emmo Urban/Kiwi E-bike/Daymak Torino upgrade

Look forward to seeing your project come along- you should make a post on the forum. Yeah I used to run a generic Aliexpress brand 20ah 48v battery (pretty sure peak discharge was like 30a or something). Now I use a 30ah generic 48v Aliexpress battery- around the same specs. I think they will be pus...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

Well I got it running just connected the 3 wire throttle, smart pre-charger and two 12v dc-to-dc converters. I'm getting some errors. CA doesn't seem to measure correct max amps. Its showing 220amps or so and my battery max can output 85a, I guess the only real way to find out is measure with ammete...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

I haven't had a chance to work on this for a while, managed to do some minor things. Prepping the smart-charger with bullet connectors, bolting down controller, DC converters, main contactor and shunt for CA. Shunt doesnt look the prettiest (on an angle) but is bolted down quite solid. Lots of bulle...

Re: Ebike scooter project QS 4kw V3 72v, Kelly KEB72601

I finished my modular battery version 1.0! I messed up by charging 4 of the 18650 cells then proceeded to put them all together. I noticed weird balancing differences within the pack. So I dismantled each stack and found the 3.5v cells (others were 4.2v). I charged them up to match the other voltage...

Ah thanks inedible. Yeah Fany said the KEB isn't bluetooth compatible, would be cool if the bluetooth to series adaptor worked. Let me know if you get somewhere with this, would be cool to have a few quick settings to reprogram the controller. Its so weird about the 70% thing, I guess I'll see how t...

Sorry I made a mistake - not sure where I got 0.2C from its meant to be 0.5C the cell nominal is 3500mah, minimum is 3400mah. They seem to use this minimum number to come up with the below from the PDF https://www.nkon.nl/sk/k/Specification%20INR18650MJ1%2022.08.2014.pdf just looking at this spec do...

Oh ok thanks. Are there certain cells that support a high re-charge rate?

Also maybe someone might wanna tell Bruno not to charge his MJ1's at 6amps! :shock:

Re: Emmo Urban/Kiwi E-bike/Daymak Torino upgrade

I got your message yes. That sucks you're ebike doesn't work. I would suggesting taking it apart and testing the circuit with a multimeter. If the bike doesn't run, it could be a number of different things- motor burnt out, controller defecting, twist throttle, a wire loose etc. I have some old part...

Re: My Chinese Ebay Build

I think 18650 are the a favorite. They're lighter etc. There's probably some way to work this out with a formula, but I was thinking the other day. Comparing the Ah cost between lifepo4 and 18650 li-ion. If you charged 18650 pack to 80% or 4v per cell instead of 4.2v I think you'd get nearly the sam...

Shawn supplied me double the metal plates for series connections, since there is a fair bit of current going through. I put the fat termi...
