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

The eMTB mode is simple to develop as well. But what takes time is making room and optimizing the function in the KT-LCD3, creating a menu and logic that makes for a great user experience, creating an "E" symbol in the assist level field, making the display and controller communicate with new param...

Re: New "TSDZ2 Torque Sensor Central Motor"

Has anyone found a full strip down and rebuild video of the TSDZ2 or perhaps a parts manual with a fully schematic drawing of the motor, just want to rebuild this box of bits I bought, just need to confirm where some of the shims are placed.

Thanks.

Re: New "TSDZ2 Torque Sensor Central Motor"

Putting in a 48v controller to use it with a 48v battery doesn't have a big influence on max pedal cadence. One should use a 48v battery on a 36v controller (with modified firmware) for that. I'm pretty sure that is not correct, all advice is to run a 36 motor on a 48 volt battery to get a higher c...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hi, my rear hub pawls have just expired with the extra loading of the motor and human combo. Has anyone any experience with a Nexus 8 speed hub or something similar as an alternative option ? Rohloff's are way to expensive, any ideas ? This happens when one shifts under load. Rolhoffs, NuVinci and ...

Grand idea today was to fit the new chainring combo so crank puller tightened in place and then the releasing bolt turned and the puller came back out of the crank, the crank completely dethreaded :evil: Anyone any ideas of how to get the crank off?

Depends on what you are using it for, but for off road, convenience and useability we have have gone from dedicated fibreglass containers mounted on the bottom bar to simple 14S2P blocks of 30Q cells in seat mounted tool bags. The bags are about £ 6.00 on Ebay, relatively water proof and yet to fail...

Re: What is " charge recovery voltage" on BMS

They are quite new cells of good quality so blaming the board more than the cells. I'll recharge them up to mid voltage manually and then recheck in the morning to see if there is a big imbalance.

Thanks.

Re: What is " charge recovery voltage" on BMS

Thanks guys,

Don't think there is any balancing going on, seems a bit strange that it simply won't charge the cells, I guess there's some sort of common failure on the charging side of the board.

What is " charge recovery voltage" on BMS

I seem to be ending up with a stack of cheapo 2S2P light packs that all have the same vault, they won't charge. They seem to be able to discharge down to normal levels where the BMS cuts in Ok. Everything else seems OK and I can charge directly to the battery by bypassing the BMS. Now in the BMS dat...

Re: New "TSDZ2 Torque Sensor Central Motor"

My first impression is holy hell it's even louder than I feared it would be after reading this thread. Do a 100 miles or so and the motor quietens down somewhat and your ear gets used to it. What used to be a bit of noisy motor now seems to be pretty normal. No it will never get as quiet as the Baf...

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

Thank you for your reply. I already bought the stlink. So the "easyest" i guess is then changung the firmware and the lcd to KT-lcd3 right? I really don't like the big lcd that is needed. So for now there is no way to keep the stock XH18 display and increase the cadence with software? Thank you Can...

Hi, I am ordering the motor from aliexpress, but there are options 48V 500W 48V 750W 52V 750W It is actually the same motor and same controller ?

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

36V stock firmware accept 11S battery, that s up 10% rpm . But that is a specialist non standard battery with a non standard charger, is it worth the agro or better simply reprogramming to take the 48v. Others have also fitted a 36v engine into a 48v unit or fitted a 48v controller into 36v unit. F...

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

There is no easy way to up the cadence I'm afraid with the standard motor direct from the factory, it is a pain for any body who cycles a lot and has a slightly more higher cadence than you average commuter. Do consider though to simply revise your riding style to a lower more torque based cadence w...

Most of these bearings are not pressed in over tightly or " LocTite " used to ensure a total bond, one can simply use a common vice to reinstall most bearings or a threaded rod and nut.

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

You are forgetting about mass and inertia, at standstill there is max torque with no ability to transfer that into motion momentarily, once rolling some of that torque is immediately transferred into forward motion which limits the amount of torque on the gears. Also consider that max torque is at o...

My unit was a bit too noisy to begin with but within about 100 miles of use it has quietened down to about the same levels as my friends 2016 Haibike.

Re: New "TSDZ2 Torque Sensor Central Motor"

Its one of the great anomalies of Ebiking, when you get a bit of power you just want that bit more. But that extra oomph has to come from somewhere and that's the battery.
