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

APR 19, 2019   Pageview:889

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.
