The Mfgr's mah rating is generally set at C/5 with temperature controlled etc. The mfgr. then decides on a % of "meet" they are willing to accept. and then uses the test numbers to rate the design.

You can reasonably duplicate their numbers by doing the same.

BUT, as indicated in my earlier posts we are really interested in flight performance. These discharge rates are different than the Mfgrs. mah test. That is why I use the discharge rate of 500ma.

By establishing capacities and discharge rates that really work in our application we can now reference check them along the life of our packs and reasonably approximate the time we should replace them.

Running a test cycle or two every 30 days (during the flying season) should be more than enough to furnish the graphical prediction as to when our packs are headed into the danger zone.
