The 26650 lithium battery is a model of cylindrical lithium batteries with a diameter of 26mm and 65mm in length, which is widely used in electric tools, lighting, toys, ups, energy storage, etc.

26650 lithium batteries also use different cathode materials as same as 18650 batteries, According to the current market application, it is divided into lithium iron phosphate and ternary battery, the difference between the two is the difference between ternary lithium battery and lithium iron phosphate battery; the former has the advantages of high capacity and high voltage platform, while the latter has safety, The advantage of large starting current.
