So recently I opened a Bosch Powertube 400 battery to repair for a customer.
I find inside 40 cells LGMJ1, cells that have 12,5Wh. So 500Wh in total.
Bosch is selling powertubes with 3500mAh cells inside, but limit them through software to 2900mAh per cell.
There is more capacity in there that's not being used. Als it limits the lower SoC, not the high SoC, so it's not even that beneficial for lifetime.
So you're paying for a battery with 20% unused, wrongly marked capacity so not according to CE rules.
