And why call Orion.....I will call Kokam and get them myself....

Hi Eddie,
The ability af a lipo to withstand storage is manufacturer dependent. I had one lot of cells where a bunch of cells puffed up just sitting there fully charged in under a month - though this only happened with one manufacturer. Most all the good Lipo manufacturers guarantee that a cell can withstand a 6 month storage with no ill-effects other than a slight loss of capacity (even fully charged) and I have literally thousands of cells in my storage cabinet for over a year and there are 0 failures. Kokam is the exception - they are now claiming 5 year storage with their latest cells, but like all manufacturer claims, I'll believe it when I get the data myself.
Compare that to my IB cells. My 3 newest packs were stored fully charged for about 3-4 months. Two of the packs have one dead cell, the last pack has 2 dead cells. All packs ($210 worth) are pretty much useless. I did a couple of cycles to wake them up (with a gentle 10A discharge rate) and one reads 2930 mAh and the second one reads 3368 mAH and the third is still cycling. I hate IB and I hate the fact that I need to buy more Nimh for the Reedy Race.
I hope you do call Kokam. Peak/Orion needs some competition when it comes to providing racers a quality cell.
Hey, wasn't this the GP thread? Sorry, off topic again.
