    I have processed about a box and a half of these and have gotten almost all sanyo, samsung, lg or sony cells. The small panisonic batteries have vtc4s with low usage, one of the boxes had a brand new unboxed module with 3 vtc4s in it. I think this is a great deal for cells and I bought 4 more

    I just finished my 30lbs and it came with 2 of those large packs with moli cells and all 48 of the cells tested between 2330 and 2492. 24 of the cells were dated December 2015 and the other 24 were October 2016. No Samsung, 9 lg 2200 cells that also tested above capacity, 12 sony, and then the rest were sanyo. About a hundred of them were 2000mah sanyo. I averaged 76 cells per 10lbs.

    You are lucky! Nice spreadsheet. I got a medical pack too, total 61 cells, lots of low 1000 mAh 18650 cells. Some nice cells of 2300 to 2400mah. 11 A123 cells- they are not holding charges. I ended up $63.87 per kWh, including those very low mAh cells. Their Mix tool packs are much worse. Lots of leak and rust cells, lower mAh at around 1300, dead NiCd pack. Also two working tool battery pack. Tool pack is around $78.14 per kWh!

    I have all those packs and more come through my supplier. Unfortunately though there wasn’t that many over the 2000 mAh capacity that most people are looking for. When the cells start with a rated capacity around 2000 mAh you are going to need a lot more to get your kWh that you need.
