FWIW - the Amazon deal - there are handling charges applied (unless you're a member of their club) and totals $111.18 at checkout.

Not complaining, still a great deal - ebay looks like there are too many watching for these pacs and with about $15 most are advertising for shipping, Amazon is very competitive.

I love to tinker and this looks like one heck of an adventure. Plan on 2 - 5S1p packs out of this. I ordered the harbor frieght stuff too for getting the cells out. I suspect this will not be my only dewalt purchase!
