26650 Lithium Ion Batteries
26650 Li-Ion Batteries are a larger variety of lithium based rechargeable batteries. 26650 Lithium Ion Batteries carry a nominal voltage of 3.2-3.7v (depending on lithium type) and are larger than their C+D counterparts. 26650 batteries are considerably lighter than rechargeable NiMh batteries and offer considerably higher energy output in a smaller form factor.
26650 cells are commonly used in vapour type devices as well as specialised LED torches and headlamps.
