The 30 cells spent the night and all day in parallel and all had the same starting standing voltage of 3.12 cells. This is after sitting for a couple days after discharge. Cells would bounce back to this resting voltage. Charger has been on for 3 hours and 12 minutes now and doing fine. I thought a cell was going to jump but it did not and is once again settled in with the rest. So far all the cells are well balanced. I will be shutting down until tomorrow and will resume tomorrow until the pack is charged. So far so good. Nice little elcon charger. Set for 3.6 volts or so from what I was told. We shall see.
