3.7V 4300mAh Low Temperature Lithium Polymer Battery Design Solution of Exploder

March 22, 2021
Latest company case about 3.7V 4300mAh Low Temperature Lithium Polymer Battery Design Solution of Exploder

The former exploder is held by human, which always leads to accident. As the development of industrial equipment, the new exploder which can explode according to time and order setting is invented. It can be controlled by internet in long distance and replace people for site explosion so as to lessen the accidents.
