Air and sea transport our battery products can be shipped to various markets more efficiently and quickly. However, air and sea transport requires professional certification in order to travel by air. When I learned about the ESTL company through the energy storage manager and saw the experimental base of ESTL, the perfect precision testing instruments and the ability of the engineers and technical teams, we recognized the certification strength of energy storage and decided to choose the ESTL as our battery product certification agency.
