Default tail cap amp measurement

if i'm using a buck driver will the measured current across the battery neg and case be lower than the actual current drawn by the diode? seems this would be so.

I believe this is correct. With linear drivers you would be able to see current draw as current output.

That is right, buck driver are more efficient than a linear drivers. The buck driver converts the excess voltage into current.

thanks, i know it works the other way with boosts. i just did a measurement of an m140 build and it was much less than i thought it should be.
