Have you stuck the key in your charging jack and blown a fuse?

On what battery version?

I have two versions of the Standard Rad battery. On which of these two types did you blow a fuse?
My reason for asking is that the BMS version is different in the later Standard Battery. It has three protection diodes that prevent current from flowing from the battery to the charging jack, and should prevent the fuse from blowing if the key is stuck into the charging jack. The earlier BMS does not have these.

Curiously, these diodes are not present in the new semi-integrated battery BMS
