A tip when doing more than one break-in cycle, is don't run them back-to-back. Since a complete cycle is charge-discharge-charge, you should run a discharge at 0.2C after the first cycle. If that shows an improvement, run another break-in, otherwise don't.
So your sequence would be break-in; discharge; break-in; discharge etc.
Dude, what are you thinking of?! If you have cells that sit idle and want to replace them, get LSD cells like Eneloops. 2700's are possibly the worst cells you could buy unless you re-charge and use them daily.I can live with out them and get some new 2700's
