Panasonic IMR 18650, 2900mAh, Flat Top
These batteries are made by Panasonic, and have the highest capacity of any high-drain battery. These batteries are hyrbrid cells, combining the longevity of an ICR with the performance and safety of an IMR. These batteries are ideal for variable voltage mods, allowing extended use over standard 18650s. These will also last a long time when used with a mechanical mod, but these are not designed for high-current applications (sub-ohm). When used at 3.7 volts with a standard resistance atomizer, these batteries offer approximately 29 hours of constant use. Higher voltage and lower resistance will shorten the lifespan, but anybody should be able to get at least a full day's use out of these batteries.
