    To prevent any confusion with the eGo-type "batteries", I use the term "cell" here to refer to a single 18350, 18650, 26650, etc.

    While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating. Carefully research any cell you are considering using before purchasing.

    Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them.

    Bottom Line
    If you are vaping at more than 10W-12W or so, around 3A, you will get more vaping time using 3000mAh VTC6's, 30Q's, or HG2's than you will using any of the 3100mAh-3500mAh batteries.

    This is due to the very high internal resistance of the over-3000mAh batteries which causes a lot of voltage sag. This forces the mod to signal weak/low battery sooner than when using lower internal resistance batteries like the VTC6, 30Q, or HG2. Even at discharge current/power levels as low as 5A/17W.

    These over-3000mAh batteries are best suited for under-3A applications like flashlights and low power devices.

    I received some Panasonic NCR18650BE batteries as a gift. Are these safe to use in vaping?

    Any battery is relatively safe to vape with as long as you stay within its ratings.
    That battery is rated at about 3.6A, approximately 13W.

    So it would seem that the 20 amp batteries are better than the higher capacity lower amp batteries in pretty much any vaping application. I've been trying to tell people that they shouldn't stare themselves blind on the capacity, that higher amp batteries will actually have more capacity in actual use at the amp draw we use them at.

    Anything above about 12W-35W or so per battery, yes. The 10A high-capacity batteries can be a good choice if at moderate wattages in a three-battery mod though. 50W in a Reuleaux is a great fit for the NCR18650GA.

    I use Sony VTC5A batteries and don't need more than that, usually. 2,600mAH and 25 amps is revolutionary.

    Mooch- I'm sure I'm speaking for an awful lot of people when I say "thank you". I've gone thru a lot of your posts, & the information/work you provide will keep a lot of people safe
