The Lil Bitty® variable voltage vape pen battery allows you to dial in exactly the right amount of power for your ultimate vaping pleasure.  Whether you are looking to get a smooth easy pull off of a traditional polycarbonate cartridge or if you are using a ceramic vape cartridge and looking for enough power for a big cloud, and the cleanest hit available on the market, this vape pen battery can do it.


Think this pen is like the others?  Ask them for a lifetime warranty.  We stand behind the quality because we don’t mess around like other brands.  We test and test until we know we have the right components and a long lasting life.  Then we back it up with a lifetime warranty that will allow you to stick with the O2VAPE family.  We want satisfied customers, and this is our way of making sure that you buy with confidence.


It comes with the specially designed usb charger for this battery with every order as well.  While the pen uses a 510 thread, this charger is specially made to charge a stronger lithium ion battery and has a design that will work specifically with this battery. When charging the lights on the battery will become solid blue when fully charged. Please click the button 5 times to turn on and off and hold the button down to get that perfect puff!


*To reduce damage to the battery, Do not use a rapid charger usb or charger that is not made for this product.

    Just charged used Lil Bitty for the first time. I have only one question, WHAT HAVE I BEEN DOING WITH CRAP BATTERIES ALL THIS TIME? I’ve had and tossed 4 Vessel batteries, not one of them worked even close to this well. Full clouds, which I’ve almost never experienced, from the jump, at all settings. Nice and small, very discreet. Thank you!

    This consistently got the best reviews online. Arrived quickly and works like a charm. Battery lasts longer than most pen batteries that I have used. Even with large hands, it still feels good in your palm. Feels sturdy, no connections issues. I was even more sold when their products come with a lifetime warranty. (Even with the fine print, it is a deal)
    Happy with my purchase. I would and have recommended O2 to friends.

    I love my lil bitty. I just bought a second one bc my cousin “borrowed” my first. It’s very powerful, easy to hold and hide, good battery life. Out of my 5 pens this is my favorite. I spent $65 on a fancier one and this is still way better. When my cart is clogged and won’t work with other pens, I can usually get it unclogged with lil bitty, she’s strong!
