Would anyone care to comment on the likelihood of any of the ini files in GitHub - stancecoke/BMSBattery_S_controllers_firmware: OSEC Open Source E-Bike Controller in a Windows toolchain for a STM8 being an ok starting point for my 18FET controller? Or is it better for me to invest time now to...

Hi all, I have a KT48 18FET controller that I bought from Pasion 4 years ago. Sticker on the controller is gone, but based on Googling this controller I would guess model number was KT48SVPRK-SJT01L or KT48SVPRK-SJT02L I'm trying out the OSEC firmware, and I can see that the OSEC settings ini...

Unfortunately Kunteng and Pasion have been unresponsive to my requests for the firmware. Does anyone have a copy of the stock firmware? Is it even possible to extract the stock firmware from the MCU, or is the MCU locked, preventing the stock firmware from being extracted?

Hi all, I am repairing a Pasion 48V 1500W ebike controller. KTE-18S5-2RX-A is on the pcb, so it looks like its a Kunteng 18 mosfet controller. I think Kunteng offers this controller with square or sine wave output, but I'm not sure which version Pasion opted for. The label has worn off the...

As my request has now changed, I'll start another thread for the firmware.
