I just did a CBA-II discharge shootout of the safe Lithium chemistries that I have discussed in other threads, such as this one. Thumbnail images, and graphs with detail capacity and how they hold voltage at 5, 10, & 15 Amp discharge rates. The factory capacity specs (as one might expect) are more optimistic than reality shows.
None of these other 6 cells have a protection circuit in them. They were all taken from various battery packs as described in this thread. I just added the nice performing AW IMR-18650 sold in this thread for $9
The cells started at room temp. They did not got warm with 5 Amp test, but all got warm/slightly hot (80-90° F) at 10 Amp discharge test.
At the 15 Amp discharge they got HOT, reaching peak temps listed below (verified by laser thermometer & Fluke 179):
Added Sony V & VT label images. See AW's sales link or post #5 below images.
