EnergyPods are modular batteries for commercial, industrial, microgrid and utility customers. The low maintenance systems provide five hour of discharge energy and are rated for a twenty-year life span, necessary for grid applications.[2][3][4][5] Primus has numerous customers including Microsoft[6], Puget Sound Energy, Miramar Marine Corps Airstation[7][8][9], HCP[10], Goldwind[11], Israel Chemicals and Victor Valley Wastewater Reclamation Authority[12].

On February 21, 2017, the company announced production of their second generation product, EnergyPod 2[13]. Streamlined for production, it features a small footprint, reduced cost of goods, high reliability components, and a sturdier enclosure. The modular unit is designed to last twenty years and supply a system capability from 25 kW to 25 MW with five hour discharge duration.

The company's energy storage systems decouple instantaneous electricity demand from supply generation, bolstering the stability and security of the electric grid, and helping accelerate the penetration of wind and solar energy. The company has over sixty (60) patents in chemistry, cell design, and system engineering granted by over more than fourteen countries.
