*The lives of public security personnel and firefighters are very precious. When they are on duty, personal equipment is not only weapons, but also portable equipment with functions of personal positioning and calling for help, which has extremely high requirements on batteries.
*In addition to basic performance requirements such as explosion-proof, over-charge and over-discharge prevention, special attention is paid to the ability to adapt to various harsh environments, such as: wide temperature (high temperature and low temperature resistance), moisture-proof, anti-extrusion or impact, etc. have basic reliability tolerance.
*Aiming at the particularity of this field, we have adopted stricter process requirements from battery cell type selection and assembly to production process. Low temperature cycle charge and discharge, continuous high temperature storage and short circuit, extrusion and other extreme tests to obtain absolute reliability of quality.
