    I'm new here...and new to sub ohm vaping. Just bought (online) an Eleaf 100TC box mod. It says it uses 18650 High Drain batteries. I've been to several web sites and I notice that there are lots of different 18650 batteries, 2500 mah, 3000 mah, flat top and so on. I haven't seen anything yet that says "high drain" batteries.

    I don't know what that means and so I am very unsure as to what batteries to order. I don't want to order batteries that are too weak, or too strong or something that's going to set my part of town ablaze.

    Can someone explain batteries to me?

    Thanks.

    High-drain batteries are those with 20amp or higher CDR; the mAh is irrelevant, you need to know the amount of amps that the battery can supply; if it's not enough, and you use a low resistance coil, you're just begging for a thermal runaway ("e-cig explosion").

    The best place to buy batteries is illumn.com or liionwholesale.com. Quality batteries which aren't cheapie re-wraps, and excellent prices.

    Thanks. Great info. What about the flat top vs not-a-flat-top? The documentation for the Eleaf 100TC didn't say anything about flat top or not batteries.

    The ones I use, Samsung 25Rs or LG HE2s (both 20A batteries), are only available as flat-tops; most of my mods wouldn't permit the very-slightly-longer length of a button top in any case.

    The only button-tops I've used were the old Efest batteries, which were for 15w-and-below mods -- old tech. Efest has such a bad rep nowadays with rewrapping and claiming much higher CDR than is actually the case, I wouldn't recommend then to anyone, unless they were going to use them in a flashlight or something. But even for that use, which at least would be safe, I still wouldn't recommend them, just because of Efest lying about the actual CDR of their batteries.
