Need some help, please. What battery do you need for the Owl? Flat top, 18650, but volt? R? mAh? Get 2 or 3? Thanks!
Flat top. Can't see how you could get the extra height of a button top in the very minimal space provided. Since the Owl atty is a dual post design and low ohm builds are so popular, I'd assume that you'd be building between 1 and 0.4 ohm. For the sub-ohm battery, you want something that has the ability to handle decent current, 20A or better. Some good 2500mah (or better) with 20A (or better) capacity are: Sony VTC5 (almost impossible to get), the purple Efest "35A" 2500mah (the pulse is 35A, continuous discharge which is what counts for vaping use is 20A {got a bad rep because of the mislabeled Amp rating but decent when you use them for what they actually are}), the Samsung "baby blues" a 20A, 2500mah battery with a powder blue wrapper. The baby blues can be had for around $6, see Vapor Joe's blog for eBay deals. The Efest purples can be found for about the same $6, lightening vapes on eBay, among others but many places sell them for more. Also be sure to get the 35A, 2500mah ones since there are at least 4 different types of purple Efest battery but just one with those ratings. LG makes a good 20A, 2500mah battery, red wrapper, but I can't remember the model number (HE2 or HE4 perhaps).
Get at least 2 batteries and a decent charger. Vape one while the other charges. If you get a charger that will use 1A to charge, the second battery should be charged before you need to replace the battery. If it only charges at 0.5A you may want a third battery. I'd also suggest that you get an additional spare. If you tear the wrap on a battery or damage it in any way, just toss it and start using the spare. Your safety, and remember we hold these things right next to our face, isn't worth the $10 that a battery costs.
Since your question implies to me that you're new to devices which take separate batteries, I'd suggest hunting for a general LiOn battery safety thread. I'd think there's one here somewhere but I'm more familiar with ECF and can't point to such a thread here.
