18650 Cell
An 18650 battery or 1865 cell is a cylindrical lithium-ion battery common in electronic devices. The batteries measure 18 mm (0.71 in) in diameter by 65 mm (2.56 in) in length, giving them the name 18650.
Dimensions
The 18650 lithium battery has a diameter of 18mm and a length of 65mm. In comparison, AA batteries (Also known as 14500 batteries) are 14mm in diameter and 50mm in length. Therefore, the size and diameter of 18650 batteries are much larger than AA batteries.
Equipment Procurement
We can help you source and procure the best equipment for your power battery from turbines to boilers, and everything in between.
Rechargeable
Although every cell has different limits, a typical 18650 battery can be charged for about 300 to 500 times. Although every cell has different limits, a typical 18650 battery can be charged for about 300 to 500 times
Energy Management
Energy management is the set of actions and processes aimed at optimizing energy consumption in order to rationalize and reduce costs without affecting consumers. Energy management involves the planning of energy production and consumption.

21700 Cell
The 21700 battery is another lithium -ion battery, and the number 21700 denotes the cell size. It comes in 21mm in diameter and 70mm in length. The 21700 battery comes with an ampere power between 3000mAh and 5100mAh.
DIMENSIONS
The 21700 battery cell has a dimension of 21mm diameter and 70mm in length. The cells are slightly larger than the 18650 and have a higher capacity.
ENERGY MANAGEMENT
The energy density of the 21700 battery is close to 300wh/kg. The energy density of the 18650 only can only reach 250wh/kg. In comparison, the energy density of the 21700 battery is nearly 20% higher than that of the 18650.
RECHARGEABLE
The 21700 lithium ion batteries are rechargeable. Because of this, it has been used in electric vehicles, vaping devices, flashlights, and many other devices that require power to operate. The beauty of 21700 batteries is their size and power delivery capacity.
