Hi, I have a Kelly KBL72301 Controller. I've changed several times the configuration of the controller until now: The red and green led lights up continuously and i'm not able to connect to the controller any more. Have i turned it into a useless brick or is there any possibility to get the...

I'm getting the same error. Any suggestions? @jonology could you fix the issue?

Similar as mine. Which motor would you use? How are the rpms and the torque? BW

Last week i had a longer call with another TÜV egineer. He gave me some hints, which the topic is related to. - First of all, there is the TÜV Merkblatt 764. It is the groundwork for all conversations. - ECE R 100 - ECE R 10 I told him, that i've read about conversations before 10/2002...

Do you have reliable sources? I need convincing arguments to convince my TÜV engineer.

Hi, I have an old Vespa V50 smallframe and I want it to convert to electric. To getting it legal, I already talked with a local MOT / TÜV engineer. He said, mechanical there would be no problem, but he want to have a EMV test certificate. I've read in this forum about similar conversations...

Yes, it is for powering my kweld. For the moment, I can get 900 A out of it. Less than I expected ( 1440 A).

Hi, i'm thinking about what would the best connection method to connect the cable to the battery nickel strips. Three methods are in my mind: 1. Soldering. Not so easy on thick cables and nickel strips are not so easy to solder. See example, my iron has to less power for the AWG8 cable. 2...

I also have a heat gun and I think, this might be no problem to solder the cable to the nickel strip. I didn't understand your comment, the pack should be a power supply for my kweld instead of the heavy lead acid battery. BW

You mean I should use copper sandwiches? I found your blog article according to RSU.

Hi, I have some A123 anr26650m1a cells leftover. I want to build a 12s3p power supply for my kweld. This is my design, I ended up with: The H-Nickel strips are 10 mm x 0.15 and the bus bar strips out of 8 mm x 0.3. I want to solder a AWG8 cabel to the bus bars. Are there any...

Hi, thanks a lot to the work of @mcc. I've ported to code to an esp32. I had some pcbs left of the TSDZ2 Project of @mspider. He developed a small PCB with an esp32 for TSDZ2 mid drives. Details can be found here: https://github.com/TSDZ2-ESP32. It works the same way as the project of @mcc...

Did someone know, If it would work with Software serial?https://docs.arduino.cc/learn/built-in-libraries/software-serial

Hi, maybe the wrong place here to ask: I've flashed the bootloader to the nrf52 as described by @casainho here: https://opensourceebike.github.io/bootloader.html My question is, is it able to restore the default bootloader and firmware of the nrf52 Dongel? Thanks! BW

Ok, now everything is working. I thought, that the esp32 is able to enable the motor via GPIO, but after reading the schematics, i've checked that the voltage regulator XL7005A is enabled via the display on. If i power VBatt and PW_EN everything works fine. I think in the next days i will...
