Thanks, the reason for that design was an mistake of an colleague which an big "Spark!".
We had used uncoded plugs in the past, but it takes a lot of care to handle that. -> Mistake!
Luckily the Lipo still alive but we had to solder an new balancer cable!
Now that my girlfriend also has an Nero , I had to find an solution to make charging "bulletproof".
Later on I will make the adapter inbuilt in a box with the connections coded like LiPo1 and 2.. or something similar.
Also I using a multiplex charger with BID and each board / box will get an chip.
It means: A girl takes a Lipo, just connecting the wires to Numbers, the charging values are already stored in the BID chip, and just pushing the start button....
What do you think, might it work?
