Oops, sorry, I should have mentioned that - standard 21700 and 18650 cells in self build 10s packs so standard BMS - no fancy comms or the like. If I did produce 42v for charging, how do you achieve the typical CC/CV charge profile?

I'm looking to take my camper to non electric hook-up sites and am wondering how I might charge my ebike batteries, so fellow forumites, what might you suggest for this please? The camper does have a 12v 100Ah lead acid leisure battery but no solar panels. I know of inverters that convert...

Thank you very much @saneagle - that is most helpful and I'm sure many other will apreciate that info too.

Hi @saneagle , Can you clarify something for me concerning the absence of a speed sensor in the motor and using something else to generate a speed signal for the controller (on the white wire). Taking a reed switch as an example, obviously one connection of the switch goes to the white wire but...

Never had a problem with PSW Power - buyer beware and all that.

Yes +1 for what @Nealh says

Before I needed the assistance of a motor to continue cycling, I had a variety of unassisted bikes, each with it's own characteristics and it was a pleasure to have the different bikes to enjoy in different ways so why when going 'e' should it be any different? My first ebike (a TSDZ2...

Hi @Woosh I love the simplicity of that freehub body but out of interest, how do the torque signals and PAS sensor signals get to the controller that is housed in the battery compartment? Is it via bluetooth or other wireless method or is the speed sensor connection in the multi-way motor cable...

When attempting to understand the meaning of the various KT controller settings I trawled through this forum and Endless Sphere and from my notes made at the time, wrote down my understanding of C12 settings. As can be seen from the extract below (for which I can't quote the ultimate source)...

Durgh - silly me - Spec Savers tomorrow then :rolleyes:

Ah, I see - I have had 'ignore' against that particular member for a long time now - inane comments tend to get up my nose but each to their own of course.

Hi Peter, apologies if I missed it, but you haven't put a price on the listing.

That's understandable but TBH in the absence of the necessary knowledge that is most likely why you were unable to get the X35 motor working rather than the motor won't work with a KT controller. I had a not too dissimilar experience when I acquired a Swytch front hub motor from a dissatisfied...

Hi @stevebry I don't know if you've seen the YT vid by 'Ebike repairs' (link) in that after Mahle X35 problems he successfully re-used the rear hub motor (although some in the comments were unsuccessful) - without know the motor parameter like the number of magnets plus the type of PAS sensor...

As I understand it this stems from BS EN 15194 which is the European and British Standard for EPACS and defines the max voltage for an EPAC as 48v, thus running a bike at 52v puts it outside the definition so if riding a nominal 52v machine then it's an electric motor bike I'd think. But I'm...
