Yes, it obviously works for your circumstances (light weight required) but its lightweight because the battery (and therefore range) is small. I don't like the way they've marketed it as a remarkable way to transform a 'normal' bike, it is just a hub kit with a small battery. As far as I can see...

No worries. The 500c is fine with the 52v, my last build was a 52v 20ah battery with the BBSHD and no problem at all. Now you mention it I do seem to remember reading somewhere that the 500C had problems with 52v but I had one anyway spare, so stuck it on with no issues. Maybe there's problems...

I've had a bit of experience with both the 850c and the DPC18 with my custom builds. Both are susceptible to water ingress/damp problems. Has it got wet lately (or even damp in a shed or whatever?). If so, I would start with ensuring all the contacts are clean and no signs of corrosion. However...

If it’s saved I’ll be using with a BBSHD with the standard inbuilt controller

Everything has been stripped off the last 4 battery cells all show zero volts, measured at the cells themselves. Thanks

I’m near Reading Neal. I must admit your depth and clarity in your explanations certainly inspire me to stick with it! I’m pretty much ready to give up on it and then you come along with an explanation and it sounds completely do-able, so thank you again for your time! In terms of replacement...

Hi there, Yes a broken wire was certainly a possibility but I’ve actually taken a reading directly from the last cell group as well and that is also showing zero volts. For some reason the last cell group has drained down to zero and nothing I’ve done so far has been able to put any kind of...

How easy? I guess I'd need to cut away the dead cells, and then solder up to a new BMS? My soldering skills aren't great! And if I removed the duff cell (which consists of 4 batteries), what would I be left with a 48v/10ah battery?

Yes, pins are outputting 5v. Had it on charge for a couple of hours this morning with the 5v charger but this time directly on the cell group rather than the Jst connection. Still not showing anything, so I think I'm going to give up! If there's anyone in the Reading/West Berkshire area who...

Thanks Matthew, Yes, I have been monitoring and as you say it’s just to get a charge into the first bank of cells.

If you’re going to make snide comments at least read the thread properly

I’ll try and get a pick today of the voltages at the various points

As Neal advised above, 5v phone charger, put through the 14th (positive) and 13th (negative) pins of the jst connector which normally plugs into the BMS

Mocked up a charger and put a charge through the pack, still nothing registering after having the charger on for nearly 2 hours. I would expect to see at least some voltage in the cells after this amount of time surely? Beginning to think it might be duff cells after all. I charged via the jst...

Thanks Neal, your explanation certainly makes sense and I will give it a try. Just need to find an old charger now!
