What exactly are y powering with it? A lifter?*

*Despite English wikipedia claim lifters doesn't work on vacuum, it's plain wrong. In vacuum, thrusting force is electron wind, instead of ion wind - much lower efficiency, right, but still generating thrust.

Although, after much consideration, I agree that including mentioned path in kp's up to 47 wasn't good practice, I think it's worth to mention that it is theoretically dangerous. Unless someone can provide confirmed example of harm done by bq27x00 and bmi simultaneous work, which, AFAIK, no one is able to, up to date. Head-less chicken or not, irrational or so, it just works.
