Introducing POLAR GEN-3: A high-performance 48V energy storage module engineered to bridge the strategic gap between traditional supercapacitors and lithium-ion batteries. Utilizing next-generation Asymmetric Hybrid Supercapacitor (AHSC) technology, this module delivers rapid charge and discharge capability, full usable depth of discharge, and exceptional durability in extreme climates.

Unlike lithium-ion batteries, STC ultracapacitors are inherently non-flammable, non-toxic, and require no active thermal management. This makes them particularly well suited for infrastructure-grade systems where safety, reliability, and lifecycle cost are critical.
