Efest 18650 3000mAh Flat Top 35 AMP
The latest Efest 18650 is a 3.7 volt flat-top rechargeable high drain Lithium-ion cell, rated for a 20 Amp continuous drain and a 35 Amp Pulse drain. Since we use these cells in our vaporizers, we're really paying attention to the pulse drain rating, which is to say we discharge the cells for a short period of time and let them rest for a bit. A continuous drain use would be something like using these cells in a flashlight, where they might be continuously discharging for minutes at a time. While we only really look at pulse discharge ratings for our application, it's still important to look at the continuous drain rating. Any higher powered device capable of firing sub-ohm coils should use a cell with a continuous drain rating of at least 20 Amps. 3000mAh refers to the battery life per charge. For example, a little stick battery that comes with the EVOD kit is 650mAh, and the built-in battery on an eVic Vtwo is 5000mAh. Considering the physical size and drain rating for this cell, 3000mAh is excellent, and will give most vapers a full day of battery life at 30 watts with consistent use. 18650 is the physical shape of the cell, which means that it is 18mm wide and 65mm long, and the 0 means the cell is round. Flat-top 18650 cells have become quite universal in the vaping industry, and will fit many popular devices such as the Kangertech TopBox and the Wismec RX200S. Consult the user manual that came with your device to be sure about which cells will fit your device.
