Anyone ever see any batteries that show no info such as temp, charge level, cel info, etc inside the app?  Have a mavic pro that is doing this on multiple batteries.  Thinking the power board is bad (https://mavicpilots.com/threads/battery-error-fix.48581/), but wanted to confirm before I go about replacing it.  Not able to do any firmware updates cause it keeps throwing an error about the battery using the app or assistant 2.

Hi there, please try to change to clean the battery connectors on the battery compartment and battery. If the issue persists, you may send the drone in for further diagnosis. https://repair.dji.com/repair/index?site=brandsite&from=nav
