Re: New "TSDZ2 Torque Sensor Central Motor"

Or is there something else to define "new version" of the motor? Cheers Apart from the black spider, helical cut main gear and spur gear, the plastic cover to the main gear had 3 attachment screws but now has 4 and is a much more solid affair altogether. Regarding noise: The power applied by the ol...

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...

Yes, thank you. I thought it might be a warning of something but having discovered that, it’s not displaying at all when disabled.

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

The ASSIST display (not the field but the actual word) blinks on and off on (both) my KT-LCD3 displays. Should I be bothered? Everything else is as it should be or appears so.

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?

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

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...

Re: New "TSDZ2 Torque Sensor Central Motor"

Thanks for the info -is the rear light worked by the down button then? The one annoyance I find with the VLCD-5 is the lights being worked by the power on off button and consequently its seems too easy to switch off when wanting to switch the lights on.

I have just converted to the new firmware a 6pin 48V 750W(new version) and an 8pin 36V 350W (quite old, 2015, and like a bag of nails) and it is awesome. The old 36v motor hasn't quite been turned into a silk purse from a sow's ear but nearly. This was really worthwhile doing and congratulations to ...

Apparently, the high backward resistance is only an issue on regular (non-coaster brake) motors when you push the bike backward because the motor freewheels at the cranks. The coaster brake version of the motor does not freewheel at the cra...

Re: 80% charge in one hour?

I think I understand the question. Some cars with liquid cooling are now pulling up to 1.7C for a small portion of the charge cycle. None are doing a full charge in an hour. However, some can definitely do 80% in under an hour, as seen in this video. The real issues are lack of fast charging infras...

80% charge in one hour?

The only way I can get an 80% charge into a Li battery is if I start with the battery fully discharged or near enough. Within +5/0 minutes (it's never faster than 60 minutes) I can hit 80% which presupposes I've towed the car to a charger as there isn't a BMS car system around that will allow a batt...

Specs for the 50E cell here: https://www.youtube.com/watch?v=_h7x6rdnD3I&t=183s Unfortunately still a bit away from prime time but soon. This cell needs to produce more power to have a better volumetric and gravimetric efficiency than a regular 18650 cell, eg LG 3,500 mah MJ1, so it puzzles me why ...

Question: the distance from center bracket to the chainring looks like 50 mm. I would like to bring this down to 40 mm.

Some of the new speed sensors with the Y split for the lights, are far more sensitive. If the spoke magnet is too close, it will actually scramble, and read very high.

Looks like the 13S4P case? Buy the case from AnnPower on Aliexpress and you get the nickel included. Note that this is, if I remember correctly, nickel plated which is a bit unusual for AnnPower as its normally 99.995% nickel they sell. Shouldn't matter.

It does not have an adjustment for bringing the sensor close to the magnet. The best I could do (see ima...
