Hi All,

I'm working on a tailor made app to configura battery packs,

It will by a standalone exe then migrated to theweb.:

Im planning to add include IR - initial volt from harvesting - lost voltage from rest - some other variables

Feel free to send me anything you would like to add / feedback and advise:

have 8 year without programming :D

But is never too late to retake goodness

If you list the voltage drop after charge then it'd be helpful to also list the charge termination current I_t (without such one may end upcomparing apples to oranges, since the voltage drop is roughly proportional to I_t, which can vary widely among chargers), and also mention how you measured it, i.e. is the first measurement before or (n seconds)after removing the cell from the charger (if the latter then you miss the instantaneous ohmic drop), and how long you give the cell to relax before taking the final measurement.

Charging method / device used
personally I charge it to 4.2 then rest 14 days
"first measurement before or (n seconds)after removing the cell from the charger" this how i usuallydo it, seconds after removing it from the charger
