Thank you for doing the tests. I always refer to your post when I have questions about a certain battery.

Great thorough review as always, thank you!

For real world results can I assume the 18350 format give ~50% better runtime than the IMR16340s?

No, you have to check the battery data. A high capacity 16340 can have the same capacity as a high current 18350.

Thanks for the review. I was puzzled for a while by the 700mAh ft, what unit is that? Then realized it was for flat top. I guess I'm acronym impaired.
