The fundamental difference is the raw material This is the general source of the various manifestations of the two.

The biggest safety difference between Li-Polymer and Li-Ion batteries is that Li-Ion batteries explode when both cells are heated to a certain degree, while Li-Polymer batteries only have chemistry.

People really don't know much about 18650 batteries, and they have never even heard of the name. They don't even know that these 5 numbers represent a kind of battery, because 18650 batteries are used more in industry, but few in civilian use.

At the beginning, the 3.7V 18650 lithium battery has an individual cycle life of about 500 to 1000 times, and the 3.2V 18650 individual lifespan can reach more than 2000. Of course, the premise is that the qualified battery produced by the regular manufacturer, if it is a defective or mixed batter......

Ni-MH battery is a kind of battery with good performance. Ni-MH batteries are divided into high-voltage Ni-MH batteries and low-voltage Ni-MH batteries.

Lithium polymer battery (English: lithium polymer, abbreviation: Li-Po), also known as polymer lithium battery, polylithium battery, is a kind of lithium ion battery.
