We recently ran into an issue with the VOXL2 where the servos weren't starting up every time connected via the M0065 expansion board. Found out it was because the VOXL wasn't supplying enough current to power the servos.

Fixed by powering the servos directly from the battery through a 5V UBEC.

HI @teddy-zaremba 
That is the correct approach. We have no mentions of direct servo support from VOXL 2 or any HW. All servos, just like an ESC, need power from an independent battery source not from VOXL 2.
Thanks for clarifying here on the Forum.
