:cry: I've been Top Balancing 16 EVE 230s in 2 8 cell groups all day. One finished around 4:30pm. The other is almost there, but it's now 10:30pm. I want to go to bed.

What to do? ?

I could shut it down and start again in the morning, But Rumor has it, it's NOT good to leave LFP batteries sitting at hi states of charge. If I quite now, am I at that Place? Is Stopping a Top Balance at nearly 3.63v per cell and leaving it resting for 9 hours a bad thing for the cells?

The bank I finished early is already discharged to 3.325v per cell. Its in it's happy place, But what should I do :eek:

Here is the first group all tucked in to bed

That's regarding long term storage of months rather than a few hours. You'll find in the AM that your cells are no longer 3.63v as well. They will "settle" to 3.5x volts.

It'll be fine to shut off the power supply and come back in the morning.
