21700 LITHIUM-ION RECHARGEABLE BATTERY
The standard 21700 lithiumrechargeable battery is 21mm around the circumference with 70mm high. The main advantages of the21700 LFPlithium-ion battery cells are that the battery capacity increases by 35%, battery system energy density increases by about 20%, the cost of the system is expected to fall by about 9% and the weight of the system is expected to drop by about 10%. Lithium 21700 rechargeable cellthat can be used to power differnent devices like flashlights and vaping accessories. GREAT POWER is a professional 21700 lithium battery supplier, and we have lithium 21700 rechargeable cell wholesale for you.
21700 BATTERY CAPACITY
The 21700 rechargeable lithuim batterywas designed to be a larger and higher capacity alternative to the 18650 battery. As with the 18650, the nominal voltage of the 21700 LFP is 3.6/3.7V. 21700 great power lithium polymer batterywas designed to replace the 18650 in the EV battery pack, it has a capacity of between 3,000 and 5,000 mAh.
The most obvious benefit of using a 21700 lithium-ion battery compared to 18650 drone battery pack is that the extra density means more energy available which makes your tools and gear run longer. We see that the 18650 batteries for power tools have a capacity of between 1.5Ah (1500mAh) and 3.0Ah (3000mAh). The class 18650 battery has reported problems, and the 2.5Ah (2500 mAh) battery seems to be the first choice for most manufacturers.
On the other hand, the 21700 rechargeable lithium battery starts around 3.0Ah (3000 mah) and go up to 4.0Ah (4000 mh). That's why the compact (1P) package we see has 3Ah or 4Ah designations all the way up to 12Ah (3P).
ARE 21700 BATTERIES BETTER THAN 18650?
18650 lithium battery cells are longer and wider in diameter than AA batteries. It is generally 3.6 / 3.7 volts and is rated at 2300-3600 mah. Lithium-ion cell 21700 is mainly designed as a substitute for 18650 lithium batteries for sale. The same as 18650, the nominal voltage of the 21700 lithium-ion battery is 3.6/3.7V, and it has a capacity of between 4,000 to 5,000 mAh.
21700,18650,20700, etc., just refer to the physical size of lithium-ion batteries. For the 18,650, it is 18 mm in diameter and 65 mm in length. The lithium-ion battery 21700 is 21 mm x70 mm. Although the explanation is simple, the differences are profound. It is easily seen by rapid volume calculations.
The additional 5 mm length and 3 mm diameter of 21700 cell battery for sale increased our volume by 47%. This is equivalent to a space of more than 7,700 cubic millimeters, used to fill the anode, cathode and electrolyte materials that can transfer energy.
21700 LITHIUM RECHARGEABLE BATTERYAPPLICATIONS
21700 cell nowadays has wide applications. With the high safety performance, high energy density and long service life of lithium-ion battery 21700, the 21700 LFP power tool battery now are being used in the new energy vehicles.
