so ive decide to get a lavatube 2.5 but cant figure out what batteries to buy. i will buying them from vaporoyalty.
You might want to send Vape Royalty an e-Mail and ask if the 18650 Batteries they sell will fit in a Lavatube with the End Cap screwed All the Way Down.
On My Lavatube, if I use a Battery that is much longer than 63mm, the End Cap doesn't. And I had to Put a Rubber O-Right under the Cap Threads to take up the Gap.
I know an AW IMR 18650 2000mah fit's fine on My Lavatube. Maybe Newer Lavatubes made from Other people than who made mine will Except Longer Batteries. Just Hard to say.
Better o Ask First then to have an do a Return if your Not Happy with the Fit.
BTW - Power-wise. All those Batteries that they sell should be Fine in a Lavatube. And Lavatube should shut down Before you try and Pull More Amps then those Batteries can Handle.
