These are a worthy successor for the discontinued AW 16340 15C. The discharge characteristics are quite different between them but the Vapcell is better at everything except the first couple of seconds.
It is and therefor the line continues past 7A, one a weaker cell it would “slowly” drop until I stop the test at 2V. A protected cell it will terminate somewhere in the chart.
The slope of the line is one way to calculate internal resistance
Thank you for the reply, and all your time testing and sharing info
I like the Vapcell 16340 INR because the button top works in all my lights. Even the ones with physical reverse polarity rings around a brass contact button in the head of the light, such as Eagletac and Jetbeam.
The Vapcell 16340 INR even works in my Atom AL, that does not like my Olight and Fenix 16340, that are longer and have flatter button tops.
Im hoping at some point, for a protected version of the Vapcell 16340, since none of those lights have built in Low Voltage Protection.
I use one of these Vapcell 16340 cells in a little Supfire S1 host with BLF-A6 driver and Luxeon V led, all resistances minimised, and get around 1150 lumen at 30 seconds. I think that is close the max that you can get with this little cell and a single led. A XP-L Hi has a considerably higher voltage than the V, and being domeless that makes the XP-L Hi less efficient as well, so I think in direct drive you will end up well under 1000 lumen.
I concur with DavidEF, the 5A discharge curve still looks sort of healthy. However, there is a large difference in internal resistance between the tested specimens. Iffy stuff which speaks bad with regards to product consistency. I also wonder about the button top spot welding quality.
