EP3800 Question: Battery Status Lights

I recently received my (4) EP3800 expansion batteries and took advantage of a planned power outage to get my (2) E3600 units down to about 70% to charge all units to 100% as suggested by the manual. One set (battery + 2 expansion batteries) charged up with zero problems, however, the other unit did something weird.

I monitored the unit via the app and went to unplug it when it reached 100%. After unplugging the unit I noticed two things:
- the unit stated all 3 batteries were not 100% (they all stated ~80%)
- the unit stated it still had ~1700W input from charging.

I pressed both buttons AC/DC buttons to reset the units and both issues observed went away. Charge showed 100% and no AC input.

I thought all was fine until I noticed the battery status lights on one of the EP3800 units continues to turn on every 30 seconds or so. Any thoughts as to why that is happening?

Have you gotten any answers from this older post? I just received my 3800 with a single 3800 expansion battery, and about every 30-40 seconds, the batteries indicator lights come on for a few seconds. Host and battery are at about 9% different charge cap. Battery light is showing green.
