Is this charging behaviour normal?
I charged my Maxamps 7.4V 6000mah 2s2p lipo on my Hyperion EOS 5idp AC/DC charger with LBA10 balancer yesterday. It was charged at 1.25amps. I noticed that when it got to 8.4V the charger didn't stop but instead the charge rate dropped 0.30amps (possibly milli-amps?) and decreased slowly (.29, .28, etc) for the time that I was observing the charging process. I think it was charging at 8.4V like this for about 10minutes before I stopped the charging process because I did not know if the charger was supposed to stop when the voltage reach 8.4V or if it needed more time. Should I let the charger continue to charge until it stops? I would think this fairly good charger would have an automatic stop.
What's the normal charging behaviour for charging lipos near the end of it's full capacity? (in terms of voltages, time, charging rate changes, etc)
Also, something less important but odd was that I had to restart my charging of this lipo three times to reach the top voltage charge of 8.4V in the above. For info, this lipo was in storage for about three weeks and the voltage reading before charging was 7.59V. I think there wasn't much mah in it; about 1000mah or less. Is it common to stop falsely (like "false peaking in charging nimh" )?
