Battery current sign convention

Hi all,

Hopefully this is a quick question: What is the sign convention for displaying battery current? Is a positive value mean we are pulling current from the battery? or should we be seeing a negative value reported in our current readings? I’m using a smart battery using UAVCAN and I am seeing a few inconsistencies and I wanted to see what sign convention Ardupilot is expecting.


Positive current means it’s drawing from the battery.
