Thanks for the timely replies!

Mine read out zero with positive on the battery housing and ground on the microSD. Pic hopefully attached. (Board in off state and not plugged via USB). Note, i did also change a jumper on one of the Grove connectors to 5V, no sensor/cables attached.

The battery itself is 3V outside of housing. -h
