Trying to figure out if I have a bad cell possibly.  Battery drops the first bar almost immediately and trips the BMS occasionally if the auger hangs at the bottom of the hole.  Other than that it seems to work fine, and according to the bluedouche app the health is "Excellent".  Checked after a few 8" holes in about 12" of ice and it was already at 3 bars, but after 37 holes it was still on 3.  Went to a different spot and did about a dozen more then it was down to 2.  Does this sound about right?
I'm a man, but I can change, If I have to, I guess.

Weak cell would still charge to top voltage though, or near enough to not be noticeable. A DEAD cell would trip the BMS and send an alert in the app for sure
