I have packs with manufacture dates of 2016, 2015, and 2014.

Manufactured by LG Chem or Sanyo Tech.

Currently I have them boxed 120 per box and a little over 40 boxes.

I have not attempted to ship these so I do not know what the logistics (legal above board or the other way around).

Each battery pack contains 4 lipo battery cells (707050) that are rated 2.2 AH per cell or about 34 WH per battery pack.

Each battery pack has its own serial number and each battery cell has its own serial number.

I do not know what the market price will hold, so let's talk about it!
 
If my math is correct (40 boxes, 120 per box, 4 cells per battery) you have about 19,200 cells on hand :O. That's A LOT of cells! And I thought my scrapyard haul of about 1000 cells was a lot gosh! Currently I am not in the market for new cells (i've got 750 of them and I only need them for an ebike, so I am swimming in cells from my perspective) but if you give us an offer we can't refuse, I'll pick up 30 of those batteries or so... (BTW, I live in michigan).

I would be all over these if they were 18650s :(

Doesn't matter to me. I would justuse these to build a really huge 2KWh ebike battery. The battery type and chemisrty can be whatever shape or form as far as i'm concerned. I don't care if it's a pouch cell, I don't care is it's a cylindrical cell, I don't care if it's a prismatic cell. For me, it's just gotta do isstore energy and lot's of it in a small package.

Yup, 19.2k cells.
Works out to 163.2kWh ~750Kg just for the cells themselves.

Not my part of the world, so even more impractical than usual.

I'm confused, what do you mean not my part of the world? Michigan is the state located right above Indiana.
