According to the formula: P=UI, U=IR. The battery rated voltage is 3.7V. For example one: If your electronic cigarette is 150W, and it use 2 pcs 18650 battery, so I=P/U=150W/3.7*2V=20.27A, it means that you need a battery more than 20.27A. For example two: If your atomizer resistance is 0.1 ohm, I=U/R=3.7V/0.1Ω=37A, it means that you need a battery more than 37A. And the Capacity is Larger is better. Warning: 1. Do not disassemble, dispose in fire, heat or shoet circuit. 2. Do not insert batteries with the (+) and (-) reversed. 3. Do not mix fresh batteries with used batteries. 4. Do not submerge the battery in water. Company Information: Quality is our culture. Quality Assuarance. High Reliability. High Density.
