Resistance of Li Ion Battery 26650, 3.7V

[cupoftea]

Hi,
Just searched the web for an hour for a Rechargeable Li Ion cell of size 26650 and 3.7V.
However, all the ones i find dont show a datasheet which gives the internal resistance.
Do you know of any that do?
We want to make our own 2S, xP stack.....with enough (x) in parallel to provide the attached current profile which is 10.1A average and 10.4Arms.

....absolutely no details about internal resistance.

Is there a "digikey" for Cells?

Why not measure it? Probably quicker than finding a
spec for something the maker doesn't feel like spec'ing.

Of course that tells you nothing about populations or
distributions. But neither does a flimsy datasheet.

Maybe one of the more mature battery mfrs has the
cell type and a more comprehensive set of applications
collateral. Tadiran?

Ultra fire is the brand that has many You Tube videos of FAKE ones.
OnBuy is also not a reputable battery supplier.

Some manufacturers give specification, specifically for "high-drain" batteries, e.g. this one https://www.xtar.cc/product/INR-21700-4200-High-drain-Li-ion-Battery-120.html

You get low impedance and high current specifically with unprotected battery cells. Should be no problem if the battery is integrated in an electronic device with own control circuit.
