Cloning a Dead Mercedes EV Battery... Did It Actually Work?

Here is the updated description, clearly highlighting that this is Part 2 of the series, along with the correct links and structural formatting. Video Description This is PART 2 of the ultimate Mercedes EQB rescue mission! After our first attempt using EQC data completely failed last week, we went nuclear. The dealer said it was completely unfixable and wanted over £10,000 to drop in a brand-new battery pack. But we knew it was just a phantom software glitch keeping this Mercedes EQB bricked. We put out a call to the community, and an absolute legend traveled all the way from Coventry with an identical working donor EQB. What followed was a brutal, non-stop marathon: dropping two massive high-voltage EV batteries side-by-side, stripping them down to the chips, cloning the BMS data, and battling a massive software sync issue with the high-voltage cutoff box late into the night. Did we manage to save the car, or did we just end up bricking two identical Mercedes electric cars? We're breaking down every single step, including the exact financial reality at the end of the video—did we actually make money on this development job or take a massive loss? 🚨 Missed Part 1?
