Re: Bafang 850C color LCD -- Flexible OpenSource firmware

Despite using my fingers to maintain electrical contact whilst programming the LCD3 display I can’t recall ever having odd results, at least not like with the 850C. Is the boot loader reliable? My hardware is hard-wired unlike the LCD3. I’ve reloaded v0.5.0-beta.3 which was jumping all over the plac...

Loaded 850C_v0.5.0-beta.5. Imperial setting still not working. Even though main screen says MPH, the speed and trip reading are both in KM/H.
Trip is definitely mph on mine and I’ll be right disappointed if speed isn’t mph as well!

To the guy who said boost wasn’t necessary with v20.0-beta.1 because you could use Emtb mode to gain very high initial power, you’re correct but not for a woman, or at least my wife who is totally sold on boost!

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

I needed a female to female 5 pin splice and just snipped a pair of Julei connectors and spliced the female ends. All seemed well until a P850 display was connected through the splice and nothing happened. The P850 was damaged, inoperable. Turned out that the Julei connectors came from two different...

Re: Help with TSDZ2 programming

Do you configure the ST-link programme with STM8S105x6? And when you do does the little led on the USB link flash blue or red? (clutching at straws ... ) Aqua’s suggestion is worth following. With 2 of these links I have each wired for the lcd and the other the motor. I was lucky, both worked.

Re: Bafang 850C color LCD -- Flexible OpenSource firmware

Is there a wiki which explains how to configure 0.4.0? I pressed simultaneously both down and up buttons and that got me into the configuration but, for example, I can’t find how to set the 36v motor up with a 48v battery. Everything appears to be working fine. I built the 850C display connector so ...

Re: TSDZ2 48V VLCD6 issues

1, 2 and 3 are all due to the same problem: the gap between the speed sensor and the wheel magnet is too close. Ignore what the manual says; it was written for the original speed sensor which was fine and then it was replaced some years ago with one which was claimed by someone on here as being more...

Re: Help with TSDZ2 programming

RST should not be connected when flashing the motor and only connect Vcc (brown wire) if your bike’s battery is disconnected. Thus at most 3 wires to connect. Very frustrating this job if you don’t do this sort of thing day in, day out. Just slow down and take care!

Re: New "TSDZ2 Torque Sensor Central Motor"

I’ve used a grinding stone attached to my drill and gently ground away whatever is blocking you getting the shaft through. Use a stone that is the biggest diameter you can find.

Some BB’s can be quite severely distorted and still work perfectly.

Re: New "TSDZ2 Torque Sensor Central Motor"

If somebody has recently bought a motor from PSW Power, would (s)he confirm that it is one of the new series? If fitted with a black coloured spider, rather than silver, is an indication that it is a new series. I ask this because every single photo of the motor on PSW outlets shows a picture of the...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

It's the indication that the off-road mode is actually ON. Well, thanks again. If I ignore the configuration menu item 10 and simply press on/off and down buttons simultaneously, off-road is disabled and the ASSIST symbol stops blinking. The settings for 10.0 and 10.1 are both 1 and remain so. Most...

It seems that the internal resistance of one cell is 40mOhm, as you have 13 in series, this gives a total resistance of 520mOhm.
Is it not the sum of the inverse parallel cells so 40 mohm per cell would be for a 4p pack 10mohm and if 13s, total 130mohm?

Any suggestions? I’ve done both the 8 & 6 pin conversions and followed the wiring as per “the Wire KT LCD3 to TSDZ2” diagram successfully so I’m puzzled that you had to reverse the tx and rx wires. The brake and throttle wires will be loose; they should be disconnected? I also thought something had...

Thanks for the info -is the rear light worked by the down button then?
