If you are not sure if you are buying the right battery for your device...give us a call! Always use 30amp or higher for anything sub ohm or TC.
Batteries are the driving force behind your mod, but they’re also a potential source of trouble if you’re demanding too much from them. When you’re using standard atomizer or tank, the reasonably high resistances mean that battery limitation aren’t much of a concern at all, but if you start building your own coils, particularly at sub-ohm (< 1 ohm) resistances, the continuous discharge rating of the battery becomes pretty important. In most cases, you’ll be using an 18650 battery, and the usual 10 A rating will be more than adequate. Using ohm’s law (I = V/R, or amps = voltage/ohms), you can see that even for sub-ohm builds of 0.7 Ω, 4.2 V would lead to 6 amps of current, which is still within the capabilities of most large batteries. However, if you start going any lower, you’ll be approaching your battery’s limits, which isn’t a wise move given that the maximum continuous discharge ratings can be somewhat exaggerated. That’s why it’s better to get a seriously capable battery if you’re venturing into very low resistances. There’s a useful guide on Utah Vapers showing the safe operating resistances for various batteries, and similar info is also available elsewhere. Here are 10 of the highest-amp draw batteries for serious, mech-mod toting, sub-ohming vapers:
