The thing about these types of gears is that they will survive without lubrication. That is after all their main advantage.

Re: TSDZ2 Blue Gear opinions

I am just curious & a little confused by this motor kit & the apparent problems with the Blue Delrin Gear that seems to fail. I have a chunk of the workshop manual and the gear is described as nylon, not delrin. It may not be Nylon-6 but maybe -12 which would be better than either -6 or delrin. Del...

Re: New "TSDZ2 Torque Sensor Central Motor"

I don't know for sure as I have limited experience with this motor but what you are describing sounds more like a Bottom Bracket noise rather than from the motor. After yesterday's disappointment I went for a 20 mile run today. I first tightened by an eighth turn the attachment 8mm bolt and checked...

Re: New "TSDZ2 Torque Sensor Central Motor"

They really should program in a softer start to protect the gear unless its something else going on causing the issues like heat softening the plastic or incompatible lubricant. Mine is the 350W model, great little unit up until now. Hopefully the metal gear will do the job. The Motus has this whic...

I hope you get this sorted. Can I just say that your excel spreadsheet of crank speed, gears etc was really useful. Thank you for making the effort.

Re: New "TSDZ2 Torque Sensor Central Motor"

I bought and fitted 6 weeks ago a 350W 36V motor with throttle, VLDC5 display and brakes. Fitting was straightforward except for the frame attachment but more about that later. Since then I've travelled 500miles and enjoyed it enormously. To begin with, I averaged 15mph at a range of approximately 8...

Re: Removal of speed limit on Dapu controller

Dapu hubs are fitted to BH Easy-motion bikes and the only way to do this is to replace the motor with a 350w one bought from the USA. I haven't done it but others have. On a repair stand the EU achieves 30 and the USA 45 kph. Such a solution might work for you. The other way of doing it is to add a ...

I would say the same for all Sunnko welders. The simple design of the 12v Arduino malectric, and the original Riba(Jakov) are so much nicer. I only wish i had saved the probe mecanisim to retrofit. I did manage to sell the parts. And get a few dollars back. I concur about the Arduino malectrics.eu....

Re: Adding a single parallel cell to boost a weak cell

Very interested if the Bluetooth/rs232 interface works. Seems to be a more efficient way of monitoring a pack than using a logger. The loggers I've seen can only handle up to 8S. Interesting that this stuff is beginning to cost a significant proportion of the battery build and, if truth be told, I n...

Re: BMS Testing

Sorry, the data is collected off an iCharger 1010B device and it occurred to me that I ought to be able to see such a slow frequency on my DVM, and I can't so it must be being created somewhere between the laptop and the iCharger serial link.

BMS Testing

This is the discharge graph of a 10S4P pack. The BMS appears to be creating an exaggerated sawtooth waveform for Cell 1 and this waveform appears whether charging or discharging. Cell 1 is the -ve end of the pack. The BMS is from Aliexpress (and is the most expensive one I've tested!) and has the co...

Re: Another 18650 stack build

LG have four legs and might ...

Modern BMS have a single pair for charging and discharging. They're bi-directional. I don't know how it's done but bidirectional interfaces aren't unusual.
