Energy Storage Connectors
Energy Storage Connectors — High Voltage & High Current Solutions

What are Energy Storage Connectors?
Energy Storage Connectors are high-voltage, high-current electrical connectors designed for lithium battery packs, energy storage systems (ESS), electric vehicles (EVs), UPS, and renewable energy solutions. Unlike standard power connectors, these connectors are optimized for 1000V high-voltage transmission and 100A–350A large current loads, offering safe, waterproof, and reliable connections in demanding applications.
With IP67 sealing, low contact resistance Radsok technology, and color-coded safety design (black/orange), our connectors ensure stable power transfer while minimizing power loss — making them ideal for EV batteries, solar energy storage, and industrial power systems.
