With parallel charging, are individual cell voltages and IR's still available? My understanding (or perhaps misunderstanding?) is that they are not, which IMHO is not ideal because the individual IR's are the "best+quickest" indicator of pack health.

I try to remember to check the IR's at the end of each charge and on a few occasions have spotted failing cells before they had a chance to cause any problems.

Also, I fly two 5S packs wired in series to avoid the weight of a separate series harness, so separating them for charging would be a hassle.
