Oh crapola... sorry guys! I'll see what I can do to straighten it out. Thinking I must not have hit 'publish' properly or something if I can see it and you cannot. I WILL get to the bottom of it, though, or just move all 10 photos over here if that doesnt work. lol That's what I get for trying to do first blog post for something this important.
And lavaman.... yeah, actually your 'best batts' are a pain in the tail to find, but soon will be easy. There's only one place that has them so far, and its non vape related. BUT in the next week or two they'll be showing up at
DiscountVapers - Your source for savings on electronic cigarettes and accessories, Go-go eGo, vGo. What you want for very safest chemistry/longest life for your 18650s are these 'Panasonic IMR hybrid 18650s' with the flat top, not the button top upgrade. They're 2200mah (means way longer life than the 1600mah ones that came with your kit. Plus, they're this new safer chemistry imr hybrid, only avail in the wooly mammoth sized 18650, so far (i think... anyone found the panny hybrid imrs in any other sizes?). Anyway, that's probably all gobbledygook to you right now, but the important thing to remember is when you want spare batts, get those pannys.

AW brand IMR 18650s are also excellent, though... just not quite the brand new innovation that the Pannys are just yet, and a slightly lower mah, which means they won't last quiiite as long as the panny's. Ones you both got in the kit are fine, they're just not the highest mah/longest life/best of the best.
Now for your girlfriend, so far, I BELIEVE that the very safest longest lasting ones that'll fit comfortably in her mini-tube are the AW IMR 18350s... lemme go hunt up the best link or two for you.. be back asap, unless someone else pops up with one, first.
Also, and i know this is such a pain in the tail.... both of your batteries would do MUCH better in a 'smart' charger, rather than the one that came with your kit. They go for 'low cost', not necessarily 'longest overall life and safest charging' on chargers they put in kits. Plus, I'm just sticking my toe in the 'best chargers and safest batts' category (after a near house fire incident that scared the tail off me....WAS not the included charger that was the culprit though, but another that i had, a trustfire.).... but after about a week's constant research, asking a ton of trusted sources, watching and reading more reviews than I EVER wanted to about batt safety etc, I found a charger, at a ridiculous low cost, that is supposedly NEAR as good as the $50 Pila brand chargers that everyone raves about. Its the 'WP2 II' charger at DV. Let me grab you a link for that right now. Now noone's saying you need to run out just this second to buy a new charger, by any means. I know you're just getting started vaping, and I PROMISE the cost goes way down after you have these initial kits and supplies. BUT it is a good idea, in the future, to invest in a good charger. Pila's are the best... they're also $45-$50 for a 2 batt charger. WP2 II 2 batt charger ($19) or WP6 II (6 batt charger $33) is a heck of a good choice. It doesn't have the same potential to heat the batts up way too hot so they become dangerous to use, or in worst case, actually vent (and that's why you want IMR batts.. if worst comes to worst they vent, don't explode. They don't have the same protections as 'protected batteries' but are by and large considered safest by most people because they're a much safer/more stable chemistry. AND they'll have much better life on your high drain device, like a vv lavatube/vtube). If you guys live together, I can tell you that I run a minimum of 4 mods at any one time, and the 2 batt charger is just fine for me, so would work for you guys. I've had mine about 2 weeks now, and i love it. Best thing... it charges any rechargable battery under 70mm long (with the included spacers) so that covers any mod batt you'd ever need to charge now, then or way the heck in the future. Its handy to have one charger that works for everything. I had..um.... 6 cheapo chargers spread all around a room, each one could charge just one sized batt. Was a housefire waiting to happen. lol Scary, but true. Also, here's a link to a review of the WP2 II... this is the "mod lady"...she's a bright one... good person to listen to.

Here's the link to the WP2 II 2 batt charger

and the 6 batt charger (in case you're a batt charging maniac. lol)
Xtar WP2 II Charger
and again, those are just for you to have, make note of, so in the future when you're ready to be super safe with chargers, you've got them. I don't have the link for the Pila's, but I know a ton of places sell em, so a search for 'pila, charger, vape' will lead you to one if you wanna go for the Mercedes of chargers.

I'll be back with good link for your girlfriend's 18350 imrs in just a few.
Ok, back. Here's some great sources for AW Brand IMR batteries in any size. Hoping most of these guys have the 18350 size you need for the mini, but if not, Wonderlite has EVERYTHING. lol You have to pay thru paypal with him, though. Here's his link. The first post explains how he works. I personally haven't ordered from him, but I've heard rave reviews by a ton of people. He's considered one of the best ecf vendors for AW IMRs, and certainly has the best selection.
Wonderlite

Two other common referrals for AW IMRs.. they won't have the size selection that wonderlite does, and not 100% confident they'll carry or have in stock the 18350s right now, but you may well want to price shop, so they're good options.
Lighthound (i believe this is a flashlight/hobbyist place, not an ecf vendor... but lots of good reviews)

And Super T Manufacturing... great ecf reviews on these guys
