TSDZ2 Info
"No, the controller is just the same and the controller can work for a 24V battery pack up to 52V battery pack. The firmware is also the same and the only thing that changes is the EEPROM values that keeps the settings for that low voltage and max voltage." - Casainho

NOTE: KT-LCD3 display is not recommended anymore because we hit the memory limit of it and so we stopped the development to it.

"I have built a number of these 850c bootloaders over the last few years. Very easy DIY project. The trick is that you must use a USB/TTL adapter with a CP2102 chipset in it. This is required by the APT software which uses a CP210 VCP driver."

TSDZ2 OPENSOURCE FIRMWARE | INSTALLING TEMPERATURE SENSOR
"Years of posted experiments by real E-bikers on endless-sphere have produced a commonly held rule-of-thumb to avoid heating your E-bike motor to above 95C (200F)."
Throttle till TSDZ2, via Y-kabel?

"When future bike in Italy and another ebike company in Korea started selling a 48v 500w Tongsheng motor last year I contacted a guy I know at Tongsheng Bicycle. He confirmed that it is the exact same motor as the TSDZ2 but with different firmware. He said the firmware upgrade can only be done at the factory and that he could provide me with motors with that firmware - just need to order a boatload of them. He said he doesn't recommend it because it pushes the motor past its 350 watt design. The good news is they are working on a new 500 watt motor that was supposed to be out last year but it is late being released. He will let me know when it comes out."

Högre volt
"I tried an 39.6v 11s battery on my 36v motor to see if I could increase the rpm of the motor. It was absolutely useful in the sense that I could have assist at a higher cadence. The main issue I have with this motor is that with a 36v 10s battery rpm of the motor is too low to assist me when pedaling fast. It starts to lay off at around 75-80 rpm with the 36v battery. 39.6v lets me pedal all the way up to 90-ish rpm. A subtle, but noticable difference.
The higher voltage produced less motor-noise and a more natural assist. It's more than powerful enough for me even though I regularily haul up to 100 kg of extra stuff on my cargo bike."

About getting Bafang 850C color LCD working with TSDZ2
"1. huge memory space of 512kbytes; 2. internal clock that means I will not need anymore to check the hours on my watch while riding; 3. fast communication from the microcontroller to LCD that should permit fast drawing of real time graphs with data like motor current, motor temperature, etc." - Casainho

Microcontoller: GD32F103RET6
This is a 32 bits ARM Cortex M3 that should be very similar to STM32F103.
GD32F103RET6 main characteristics:
Maximum Speed Up to 108MHz
Flash Memory: 512K
RAM: 64K
Package: LQFP64
Dom som tillverkar P850C
http://www.aptdevelop.com/index.php?m=articlee&a=index&id=130
Finns 850c och även P850C, verkar vara P modellen man ska ha.
Om beställer från China, så verkar den billigast hos PSWPOWER
