Features:
18650 lithium-ion batteries have a long service life, with a cycle life of over 500 times under normal use, which is more than twice that of ordinary batteries.
Proper maintenance and usage can further extend their lifespan.
The voltage of 18650 lithium-ion batteries is generally between 3.6V and 4.2V, much higher than the 1.2V of nickel-cadmium and nickel-metal hydride batteries.
Unlike some other types of batteries, 18650 lithium-ion batteries do not have a memory effect. This means they can be charged at any time without needing to fully discharge them first.
18650 batteries can be easily serialized or paralleled to form larger battery packs, providing flexibility in design and capacity.
