VOXL Inspect Battery

This tool subscribes to the /run/mpa/vvpx4_sys_status pipe published by voxl-vision-hub which provides a copy of all SYS_STATUS mavlink messages received from a PX4 flight controller. Among other things, this packet contains battery status information which can be viewed here.

Also note that voxl-portal subscribes to the same pipe and also shows battery percentage in the top right corner of the webpage.
