It says "DO NOT USE TWO OF THESE WITH INCANDESCENT LAMPS" in the description. An atty is pretty much the same as an incandescent lamp with a glowing filament. I'd be more hesitant to use these than the Tenergy one's.
no it says don't use 2 of these stacked with 6W incandecent lamps..
totally different than our atties....
I've also emailed the AW dealer and asked why you shouldn't use them with a 6W incandecent bulb...and it's because they can't drive a 6W bulb efficiently on a continuous discharge..and in a continuous discharge situation in a flashlight without a voltage control chip the voltage drop off is rapid..which is totally a flashlight specific concern..
someone else asked if they could power a 10W lamp with them...and the reply was that they might have to use 4 of them to power it efficiently...so really it's a disclaimer for efficient runtime for a 6W incandecent (which has a higher draw when you switch it on) bulb..again flashlight specific concern...we're using them in bursts not in a continuous draw situation...but max drain rate still comes into play.
look I get it you like the tenergy batteries..I don't because they have a crappy max drain rate...any atty that we're running will exceed that which means they're getting the snot beat out of them..
Honestly til I saw that those AW LiFePo4 were good for up to a 10C discharge rate I didn't think there were any good batteries for 6V vaping..
But in researching further these I trust...the tenergy not so much..
And though I like lighthound as a dealer well there's no explaination... I'd much rather trust the AW dealer (and he doesn't have the same disclaimer as far as 6W incandecent bulbs) ...here's a thread all about the AW LiFePo4:
