Understanding Battery_Status reading QGC

Hi Guys,

I’m trying to make sense of a reading I’m having for a custom drone (quadcopter 550) that we created.

For the battery current, we are measuring a 12 seconds operation by RC, incrementing the thrust slowly until it lifts and then a soft landing. How can it be that we are only reaching 3,6A? Batter is 4 cells LiPo 4,2V each, We expected to measure something like 1000 watts. Does it make sense?
