26650 or 18650 configuration

[QiQi]

Hello,
i wanted to ask if 2 x 18650 batteries is good enough for a 6W 445nm laser
or should i better pick 2 x 26650?
is there a massive difference in capacity between the two or is the difference not that big?
because i would like to have the 2 x 18650 configuration so the laser can be heavier and more solid
But i don't know howmuch power a 6W laser consumes
Will i be fine if i choose the 2 x 18650 configuration?

The laser will be and feel heavier and more solid with the physically larger and heavier than 26650 batteries not the other way around as in your post, if that is what you meant by "be heavier and more solid" Your meaning is not very clear.

If the laser's battery tube is sized for 26650 then you need adapter sleeves to use the smaller diameter 18650 batteries.

Either will work fine with but 18650 will have less run time and need charging more often if you are meaning best quality and highest mA capacity 18650 and 26650 batteries.

really depends on the battery too. times will vary

Personally I like to use the densest, largest possible batteries in my builds to maximize runtime

Hi,
I been using Panasonic 18650 batteries for the NUBM44-V2 they are fine and give plenty of run time before charging.

Really? So the laser with the 26650 batteries will be heavier than the thicker aluminium tube with 18650 batteries?

Ok thanks

I assumed you were talking about an already made laser battery tube that could use either 26650 or 18650.
You said nothing about thicker or thinner battery tube. If you want a heavy laser have Lifetime17 make you a host made of copper.
I was saying simply a good quality 26650 batteries are heavier and larger, about 100 grams, than good quality 18650 which are smaller and lighter in weight like the Panasonic18650B Lifetime17 mentioned wiil work just fine and weighs about 46 grams regardless of aluminum tube internal diameter or wall thickness.
