Thanks for the helpful tips rcnewb2004. I guess its time to buy new packs and put my old cells for practice only. So if i start using the I.C.C from day 1 for the new cells, will it help to maintain my new cells for a very long time? How long can a new pack of cells maintain their full capacity? 1 year? 2 years? Please note that i am using the spintec battery manager too.Any info will be much appreciated. Thanks
