To discharge or not to discharge

You'll probably find as many people who discharge their left over packs after a day on the field as those who don't and leave it for the following weekend. I personally try to discharge any left over packs if I'm not going to be flying for at least a week. So I thought I'd give this a go to see how quick this could do it as well as to check on some packs over their life span, see if or by how much capacity they will drop from new over the life of the pack9s). It's a bit early to draw any conclusions but this does what it says on the box, and with the bluetooth interface it's quite good for getting the data from each pack after a discharge. Lets see how it goes over time.
