So... basically just asking you to confirm that power consumption defined in firmware for both tracking and slewing really is as intended, and a heads up for you on possible battery run time impacts. 
Hi Bob, thanks for the feedback.  For the EXOS 2 I changed the current from 600 mA (tracking and slewing) in 9T10/11 to 700 mA (tracking and slewing) in 9T13/15 and then in 9T17 to 600 mA (tracking) and 900 mA (slewing). I have confirmed these numbers in the firmware code.

If you are mostly tracking then the motor current should be the same as you saw in version 9T10/11.  I can send you a custom firmware with only 600 mA if you like to compare. I increased the motor current during slew so that it would overcome more inertial load and also overcome a little more imbalance. Let me know what you would like to do.
