I’m upset that the 4th cell along in that picture has been glued in with an extra 2.6 degrees of rotation.

Got cells from Lion wholesale today. Funny but they’re a little different than the ones I got from eBay. Both have authenticity sticker and same print. Positive terminal is different and diameter is different. LW on left, eBay on right. LW fits spacers. One might be an older version? I might be crazy but I ordered more from LW to make sure my pack has perfectly matched cells. Gonna set the 12 from eBay aside. Prob post them on the eboard market.

eBay must have sold you fakes? Do you have a battery tester to test the mAh and voltage curve?

They came in authentic boxes and had same print and authenticity labels as the one from Lion Wholesale. What tester do you use for that?

Could you contact liion wholesale? Maybe they maye shed some light on this… at least they should be aware that such batteries exist, I think.

is the weight of the cells matching with the specs? I did read somewhere that fake cells would be lighter…

I seriously doubt that they are counterfeit. Probably just an earlier version. Anyway, I’m testing a couple of them to see what their true capacity is. I’ll post results shortly.

hot glued and spot welded.

spacers take up too much room in the box in my opinion.

Nominal voltage 3.7v for Li-ion

@Namasaki li-ion is 3.6. Lipo is 3.7.

@delta_19 of course its blood. Most likely virgin blood of the innocent. And hell yes skatan can certainly help you make good packs as long as the requisite blood sacrifices are made.
