In addition to what dereckbc said, the specific job will determine the requirement. Use the same power formula to apply to the charge job. An example might be charging a tiny rx battery using 2 amps...

The series cells need to be at a low voltage point (discharged state , resting and room temp) volt readings logged.

Then charged in series to a high voltage point (without any balance...

My guess is that the cell 4 is too high or too different than the others. The diag should be to balance all at 3.9 and then test at the upper and lower limit. This will tell you that cell 4 is either...

I tend to use the very cheap "extensions" in 2s,3s,4s,6s and leave them always plugged into the charger/boards. I use them mostly to be able to reach the battery. Both of my chargers look like...

My best practice has been to decide to fly , charge fast then fly hot. Two planes can be kept flying almost non-stop.

Good advise here, a good sure way to verify individual cells. The readings are suspiciously pointing to a misreading of the cell no. since as lipos are very predictable.

A good way to check is to wiggle stuff during a charge or discharge, a good connection should still be rock steady.

The low cell could be the highest IR or smallest cell if those readings are taken after voltage springback occurs , but I took this reading to be "during the charge" in which case the highest IR or...

the 4.04 is probably your best cell. If that's the only pack that cell 1 lags then it "could" be a connection , but unlikely. It's probably just a mismatched IR and/or capacity.

On many chargers there still may be good reason to connect the balance lead even when doing a regular charge.

I've got a couple of cells that I just discharged for disposal and I'll check this out to see what transpires upon recharge.

If a cell shows a lot of voltage bounce then it probably has high IR. GIven the info that it corrected quickly leads me to suspect the cell , connection, or tester.

For your normal folks , there's not much regulation during the discharge. There is self regulation during the charge. That is to say that is entirely possible for the user to overheat a pack during...

I guess I get in a hurry. My packs get hotter during a charge than they do during flight. Probably because I charge much faster than I use them. I use temp to establish my own max rates for all my...

Lipos no. none. But you have to wait for any voltage springback or temp recovery. If the temp doesn't go down then neither does the voltage.
