Huzzah! It's working as it should!!! Thank you for the ideas and suggestions!

Well... if nothing else I found a cold solder joint on the Mod's positive XT30 connector, which I fixed and put new heat shrink on in the process. I put a brand new LAVABOX 1,300 mAh battery (Crazypony) extender pack (the screws had seen their better days and the prior owner had damaged the top corner edge of the back plate) on the Mod following the balance charging plug removal, cleaning, and replacement. It's been over 48 hours and EVOLVE still hasn't contacted me on my ticket. So much for the 24 to 48 hour response. I will update with any further results.

Basically 24 hours after full charge Cell 1 = 4.18, Cell 2 = 4.19, and Cell 3 = 4.08. This validates the observed drain on Cell 3 after four days (reading of 3.7). I removed the board and visually inspected the balanced connector on the board and there is nothing visible that would indicate moisture, oxidation, or other continuity issues. I will de-solder the connector tonight, clean it and the board contacts, and solder it back into place. Photo of readings attached.

I will check that but I haven't had any noticed tank leaks. It's now down to 4.12 on cell 3.

It seems that the DNA 200 board in my LAVABOX is discharging Cell 3 (likely an issue with the charging section). Any LiPo I put in her (the 900 mAh and two different 1,300 mAh) has cell 3 down to ~3.7V after 3-4 days while cells 1 and 2 are still at 4.18. Since I'm past the manufacturer's 90 day warranty, I thought I would seek insight from the forum on what to do. I've also posted a ticket with EVOLVE yesterday (Ticket tracking ID: DBU-69N-X6G6) and waiting to see if they may do something. Static discharge after about seven hours, on a new LiPo after it was balanced charged on an external charger and all were at 4.20 volts at the start, C1=4.20, C2=4.19, C3=4.17. I will reconnect after work today to see where they are at.
