In case you are far away from Germany or don’t want to spend the extra money sending your PM to SRM, this guide shows you how to attempt a DIY. I had no knowledge of the product design or variants of the mechanical aspects. This guide was created through observation and basic electronics knowledge. I did perform the battery swap on my own PM that I continue to use for training.
In case you are lucky to get a later model, I believe the battery replacement can now be performed by yourself.
Good Luck!
