How soon do you expect your LiPo to not charge to 4.2V/cell anymore?
I've got about 20 cycles on my three batteries now and it looks like they are starting to top out at 4.19 / 4.18 per cell now instead of 4.20.
Isn't that a bit early?

What kind of packs do you have ?

One E-Flite 1800mAh that came with my Blade 400.
Two Cellpro Evolution 2100mAh
All three have gotten about the same usage.
All three seem to start having this problem.

How about the flight times, and mAh returned, is that pretty constant ? I they had been a certain brand pack, I would have said yeah, expect it, but I don't have any personal eperience with the Cellpro. I have packs going on 200 flights still taking 4.2 volts.

.02V is almost nothing. Don't even worry about it. My cells (on 8 packs) can range from 4.14-4.20. All packs work very well and when I measure a pack across the discharge leads, they measure 12.59-12.6V...perfect. I know 4.14-4.19v x 3 isn't 12.6v but somehow it works out. What is your total pack voltage?
