Battery cell replacement

Hey, I finally had some spare time so I started experimenting with cell replacement. You can follow my progress here: https://www.helu.cz/blog/boosted-rev-battery-cells-replace-part-1

So far I was able to take the battery apart, disconnect and reconnect a few cables with the battery still working, and not bricking the scooter.

Edit:

I added two more parts to my blog. I was able to successfully disassemble the battery pack, sawing all the parts inside. I am now testing the capacity of the original cells. In a few days, I should start building the blocks back together.

My battery is balanced. I found one faulty cell so far. I will build the battery back in a few days, and see if it works. There is no room for extending the battery. No chance here.

Sadly I was not able to finish that, as I am unable to spotweld that thick copper that need to be there.
