I am currently trying to determine the anticipated amperage draw for a large X8 platform that our team is using to carry a ~10lb sensor for use in the field of snow science and hydrology. It has (fortunately) come to my attention that we need to reduce the 22.2V coming from our batteries to under 18V when supplying power to the PixHawk using the standard power module, which came with the PixHawk flight controller. It seems that we have two options:
1) New power module with increased power handling capacity
2) AttoPilot - I'm still unclear as to exactly what this would do although many other forum posts on this topic have addressed this to some degree.
My question is twofold -
1) Which option, if any is the best route to take. What specifications need to be met so I don't max out either option?
2) How to calculate the theoretical amperage draw from an X8 (sets of two coaxial motors). I have not found much material on how to calculate theoretical values for this type of configuration since the motors are 'working in tandem'? Does this matter? Help here!
