The two cells tracks perfectly, they handle 15A nicely. It looks like they must be drained fairly low to get full capacity.

They may handle 15A nicely, but they do get rather warm doing it.

Very interesting !
Thank you for your time and effort.

Would these be considered
FLAT top, or BUTTON top ? ? ?

Flat tops.

Cell manufactures like LG, Samsung, Sanyo, Panasonic and Sony don't ship their cells with button tops.

They're added by 3rd party rebranders, like Keeppower, Orbtronic and EVVA.

How does this cell compare
to the very similar Samsung INR21700-50E ?
(cyan or blue color)

Specs look almost identical.
What am I missing here ? ? ?

Thank you for your assistance.

I know of two companies that sell the 50G with their own labels. But, sold as a Samsung 50G? Not yet.
