You were right, that connector was a struggle, but it is out. 10 white and 1 black in it

I have now got hold of a meter & taken the battery internals out of the case. I initially took the top off the battery & there was a crack/spark after I had removed the lid. I do not think I had disturbed anything at this point, so maybe indicative of a damaged/poor/dislodged connection? I would...

Hi Bikes4Two, thanks for this. I will also look at the condition of the joints when I take the battery apart. I hope you did find the problem and you continue with no issues :)

This info is great, thanks very much. I am well up for trying to find out more about what has happened. It will take me a couple of days to get hold of a meter and find a bit of time but would really appreciate the support.

Should I leave it on longer?

Charger was green when I got that voltage.

I have just checked after approx 6 hours charging and is showing 40.6v. Does this indicate anything? Thanks again.

It is on charge now so will update as soon as charged. Its not been used since the problem happened & when I checked today just before charging, it was showing 2 (of 4) bars & 37.6V on the controller.

Hi NealH, I mostly use PAS2-3, sometimes 4 or 5 to get me home up a gradual hill if its been a long day, but rarely 5. I have never changed the setpoints of eash PAS level from the default. I think the controller is 7A/15A, but will open the box & check.

Thanks all for the replies, been away the last couple of days so not managed to do any more investigations yet. Hope to later today or tomorrow. After reading all of the above though, I was also thinking that it doesn't seem to have been a gradual drop in performance, just suddenly one trip when...

It looks like the lcd5 does allow a real time voltage display so will have a look at that too. Would it be that the BMS cuts all power when it sees the voltage drop, or would the controller be doing it?

Thanks for the replies. The battery is a 36v 11.6Ah with Samsung cells. (I am just trying to remember which cells they were). I would be surprised if /disappointed if the battery is on the way out, as it has only done <1000 miles in 2 years. So not too many charge cycles, I haven't been overly...

After nearly 1000 trouble free miles I have just hit an issue that I can't explain & was hoping some of the vast experience here may be able to help me. I have a MXUS XF08C rear wheel motor with KT controller & KT LCD5 display. Last night when riding home, about 5 miles in, the whole system...

I bought a kit with the same issue, but started to ride anyway. What I hadn't realized was that the wheel had also not been built properly, the spoke tensions were way off. After a couple of rides the wheel was close to collapse & I even had a couple of spoke nipples bouncing around inside the...

I converted a Trek MTB for £350 (kit & battery). For that I got a MXUS rear hub kit (PSWPower) & 11.6Ah battery from Yosepower with Samsung cells (29E). Issues I had were a poorly built wheel (£10 for re-truing), needed to buy a different PAS to suit my bike & also purchased sensors for...

As my commute is relatively flat, I am happy to get up to speed myself, so not relying on assistance to get me to the point where inefficiency & wasted heat are a big concern (so 50% of no load speed of a 328rpm motor @26" = 12.5 mph. Then once I am up to speed, I could use some assistance to...

Thanks for the replies. I am starting to think I should stick with what I have as it has only done ~200 miles & has had no problems. Just one other question though, to get assistance at higher speeds, would it be feasible to limit the controller setting for PAS level currents to the capability...

7A/15A

I will check the controller output when I get home; I think it is 7w/15w

Do I need more power if I am happy with the equivalent drop in torque if I keep the same power source? (ie. battery & controller). Could I find a motor that will operate at those speeds, and give me a lower level of assist at a higher speed? I am happy to get up to speed via pedals if the motor...
