 Now 4:18pm, cells measure once again at 3.35V (15W). Now 4:18pm, cells measure once again at 3.35V (15W).

 +Another day of charging at the cabin.
 +
 +====20220501====
 +While the sun is out, getting some charging in.
 +
 +Each resuming seems to restart us at the 3.32V/3.33V range, and a higher initial amperage (6A, 20W), and then dwindles throughout the day. Cells measuring 3.36V at the end of the day in recent days.

 +====20220503====
 +Started charging the second group of batteries.
 +
 +====20220505====
 +Second group of batteries, charging since Tuesday, are now up to 3.32V.
 +
 +====20220512====
 +After paralleling all 8 on Monday afternoon (20220509), and had upped the voltage to about 3.55V, I arrived today to find them fully charged at 3.4V (0A, 0W!)
 +
 +So, I upped it to 3.65V and left them to charge. Had a nice 7A+ going. Not sure if I am keen on leaving them to charge through Saturday. We will see. Pleased though that we seem to be wonderfully close to complete with this endeavour.
