I got my V6 4 Years ago and was a bit Worried about the Batterypack This is no Issue, just a Hint. I am unsure where to give feedback, so close it after you read it.

I had some trouble uploading the new code in the Beginning. The Original Firmware seems to allow Connections attempts only in the First x Second (2-3?) after the Button press.

The first time I connected everything, pushed the Button, loaded the Firmware, and clicked "Connect." after maybe 10-15 Sec. Nothing happened; except "Connection Time Out." After the 5-6 Attempts, I remembered the same happened with some Pro Micros I used. So Connect and Button press at the same time... It WORKED

So, my Battery is Flashing Colors now; It Blinks 6x Green on Button Release and 1x Yellow on Charge Yeyyy

Thanks for the Effort

On original firmware the bms ic will stop providing power to the mcu after few seconds, only way is to make your programmer output 3.3v to keep the mcu powered

Ah okay that explains my problem But if you are fast enough it works anyway

So I just leave it here if anyone encounters the same Problem :P
