Key Features of Energy Storage Connectors
One-click quick plugging and unplugging
The male and female ends are locked using a press-type latchdesign, which offers advantages such as secure and reliable locking,smooth insertion and extraction, and can withstand up to 500 ormore insertion and extraction cycles.
Diverse options
Available in black and orange, with currents ranging from 50 to 350A,meeting the needs of energy storage devices. Customizable with red,white, and other colors of casing.
Comparable to materials from major manufacturers
The shell is made of PA66+GF material, ensuring stable electrical performance and excellent physical and chemical properties such ashigh temperature resistance and corrosion resistance.
Strong conductivity
The conductive components are processed with silver and tin platingon the surface, ensuring excellent conductivity and meeting the tem-perature rise requirements of the product even under high-tempera-ture conditions.
