We develop industrial-grade explosion-proof, anti-interference and high-stability lithium batteries for scenarios such as rail transit on-board backup equipment, track inspection equipment and on-board auxiliary power supply systems. Featuring strong shock resistance, temperature tolerance, high safety and long service life, the batteries adapt to the harsh operating environment of rail transit, ensure continuous and stable power supply for on-board equipment and inspection devices, and meet the industry standards of high reliability and high safety for rail transit.
