It's my first post here - please be merciful to me 
I own a B250e built 01/2017 since about 5 years. As even battery warranty runs out in january '25, I wonder if someone ever did some repairings on the main battery.
Sooner or later, all of our batteries get worse and some cells might be dead and as it's a tesla manufactured battery, I guess they are almost similar to model s batteries from 1st generation.
There are forums, where model s users explained that they repaired their batteries themselfs.
I am a electronic expert and build my own (low voltage) batteries for solar energy storage since a could of years. Also microcontrollers, etc. is well know to me.
So far my Benz does great, but I want to be prepared. Also identifying error codes (in the past covered by warranty) would be fine. Right now, it's hard to do any maintenance in such cases from errors like "visit a workshop".
All I know, is to get either "star diagnose" or xentry software and a cheap 20$ connector like "Tractrix Openport 2.0".
Is anybody here experienced with this?
