Problem
Lead‑acid batteries used in automotive starter systems, industrial equipment, and UPS units are heavy, have limited cycle life, and can pose safety risks due to acid and low‑temperature performance, especially in hot and humid environments.
Solution
Sodion Energy provides 12‑volt sodium‑ion battery packs that serve as direct, drop‑in replacements for standard lead‑acid batteries. Their packs match the physical dimensions of existing batteries and are compatible with automotive alternators and typical 12‑V systems, eliminating the need for redesign. The sodium‑ion chemistry eliminates lithium and acid, offering a safer, non‑flammable solution that operates reliably up to 70 °C. Compared with lead‑acid, the packs are up to 60 % lighter and deliver 2–3 × longer cycle life, reducing total cost of ownership. Sodion offers a portfolio covering starter batteries (Prometheus II, Prometheus Lite), backup monoblocks (Argus), and industrial traction packs (Kratos), each engineered for high‑temperature, high‑humidity conditions common in tropical regions. The company integrates proven SIB cells from leading manufacturers and provides project‑specific engineering, warranty support, and technical assistance to ensure reliable deployment.
Target Audience
Primary customers are automotive manufacturers and fleet operators, industrial equipment makers, and UPS or backup‑power providers seeking lighter, safer, and longer‑lasting 12‑V power solutions for tropical or high‑temperature deployments.
