Absolutely not.
Ordinary 18650 batteries are different from lithium batteries used in model aircraft. Because ordinary 18650 batteries cannot replace model aircraft batteries.
Model aircraft batteries require high discharge rates. For example, batteries rated at 3.7V, 1500MAH, 20C mean they can be continuously discharged at a current of 30A for at least several minutes, while ordinary 18650 batteries cannot do so . This. Typically, the helicopters played by children use 370 brushed motors which require 7-8A of current at 8V to operate properly. They are usually equipped with 7.4V, 850MA, 15C lithium batteries at the factory.
The theoretical battery life of the 18650 is 1,000 charge cycles. Due to their large capacity per unit density, most of them are uused in laptop batteries. In addition, because 18650 has very good work stability, it is widely used in various major electronic fields: often used in high-end, portable, bright flashlights. Power supplies, wireless data transmitters, electric thermal clothing and shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments, etc.
