Green Batteries for a Sustainable Future.
We specialise in 12-volt Sodium-ion Battery (SIB) packs that replace lead-acid in vehicles, equipment and stationary systems. From starter batteries to industrial and UPS systems, our products deliver safe, reliable energy where it matters most.
About UsWhy Sodium-Ion Batteries?
60% lighter
Up to 60% lighter than lead-acid batteries.
70°C tolerant
Reliable high temperature performance.
0% Lithium
No lithium or acid for improved safety.
Up to 3x life
Lasts 2–3x longer than lead-acid batteries.
Prometheus II
Our premium 12-volt sodium-ion starter battery, engineered to outperform AGM in tough conditions. Prometheus II delivers dependable cranking in heat, humidity and daily start-stop traffic, staying consistent where lead-acid struggles.

Sodion Argus
A sodium-ion monoblock designed for dependable backup power. Argus delivers stable runtime, long cycle life and consistent performance in heat and humidity, making it a strong replacement for lead-acid in UPS and stationary systems.
Learn MoreMove Beyond Lead-Acid
Sodion 12-volt SIBs are engineered as drop-in replacements for lead-acid, fitting standard sizes and working with automotive alternators and most 12-volt systems. They deliver lower weight, longer life and better overall economics without major system changes.
Our packs are built on IEC 62619-compliant sodium-ion cells and contain no lead and no lithium, removing acid spills and reducing fire and thermal-runaway risk. They hold performance in tropical heat and humidity up to 70°C, last 2–3x longer than typical lead-acid, and weigh up to 60% less — cutting maintenance and total cost of ownership across automotive, industrial and backup-power use.
Built to Standards
Safety and reliability are engineered in, not added on. Our packs are built on sodium-ion cells that carry recognised industry standards, and the chemistry itself removes the most common failure modes of both lead-acid and lithium-ion.
IEC 62619
Compliant sodium-ion cells for industrial and stationary use, validated for safety and performance.
No lead · No lithium
No acid spills and a very low fire and thermal-runaway risk, so packs need fewer protective systems.
Rated to 70°C
Stable runtime and cycle life in tropical heat and humidity, where lead-acid degrades quickly.
