Lithium Werks'' 18650 cells are capable of delivering very high power due to its use of patented Nanophosphate® battery technology. Based on lithium iron phosphate chemistry (LiFePO4), the cells are inherently safe over a wide range of temperatures and conditions. Whether the application requires outstanding cycle life or stable float

This means that an 18650 cell rated at 2,000mAh can provide a continuous load of 20A (30A with Li-phosphate). The superior performance is achieved in part by lowering the internal resistance and by optimizing the surface area of active cell materials. Nickel-based batteries have low numbers and lithium-ion is even better."

The 18650 battery is a Li-ion battery named after its 18mm × 65mm cylindrical size (diameter × height). When compared to AA size, it''s height and diameter both are larger.

When it comes to working with 18650 cells, learning the process of inspecting cells for visual damage, testing cells for voltage drop, and performing a proper charge and discharge test for each and every cell is crucial. Remember, if a lithium-ion battery pack is built with unmatched cells that have many different capacities and internal

The stronger heating and lower resistance of 21700 cells than the 18650 results in higher polarization in the 18650 and deviations between the voltage curves for the two formats at higher C rates. The 21700 has about 50% greater capacity and energy density than the 18650 for discharge rates up to about 3.75C.
