I have been using Panasonic NCR18650B batteries in my evic for a few months. 4 of them in rotation. Was getting two days on a charge until recently. Now, they seem drain like a flushed toilet. Two hours ago, I was at 45%. Now 10%. Not sure I am doing anything different. Vape at 9W/4.5V, maybe 6mil a day. iClear30S - reading currently 2.3 ohms.

Xtar VP1 charger (which I like a lot), charging at 500ma. eVic set properly for the battery, though not sure what that does if anything.

Something has gone wrong, and I cannot believe that the batteries all went South at once.

Ideas? How to debug this? Very annoying.
