Next-Generation Stop-Start Power: The StratoForse!
Uncompromising Endurance for Modern Vehicles.
Modern fuel-saving vehicle technology demands a lot from a battery. Frequent engine starts and heavy electronic loads can quickly degrade traditional lead-acid and AGM batteries. Enter the StratoForse series: a revolutionary line of Polyanionic Sodium-Ion (NFPP) batteries specifically engineered to thrive under the intense demands of Stop-Start systems.

The StratoForse Series represents a comprehensive line-up of sodium-ion (NFPP) starting batteries designed for automotive, stop-start, and heavy-duty commercial applications. These models deliver high cranking power, ranging from 350A to 950A CCA, while remaining approximately 60% lighter than traditional lead-acid alternatives.
Key features across the range include:
- Broad Application Range: Includes standard JIS and SAE fitments for passenger cars, specialized high-demand Stop-Start systems, and all-in-one 24V commercial packs.
- Extreme Durability: Each model is engineered with a flame-retardant PC+ABS shell and internal fixation kits to provide superior vibration resistance and thermal stability from -30°C to +80°C.
- Reliable Performance: The series supports between 120,000 and 180,000 engine starts and features a "superpower" recovery capability from a 0V dead-flat state without sustaining severe damage.
Download a Technology Overview
Sodium-ion (NFPP) technology shatters the traditional battery trilemma by delivering the high-performance cranking power of Lithium with a safety profile superior to Lead-Acid. Engineered for extreme reliability, these batteries offer zero risk of thermal runaway, a 60% weight reduction over AGM, and the "superpower" to recover from a dead-flat 0V state without damage.

- Ultimate Safety: Highly stable Polyanionic (NFPP) chemistry ensures zero thermal runaway and fire risk, even under extreme stress.
- Extreme Resilience: Operates flawlessly in punishing temperatures from -30°C to +80°C without the capacity collapse seen in AGM or Lithium.
- Unrivalled Longevity: Built to survive up to 180,000 engine starts and over 3,000 cycles, providing the lowest total cost of ownership by eliminating frequent replacement cycles
- Zero-Volt Recovery Power: Unlike AGM or Lithium batteries that suffer permanent damage or BMS lockout when fully discharged, Sodium-ion (NFPP) technology can be drained to a 0V state and fully recovered without severe capacity loss.
- Massive Weight Advantage: Sodium-ion batteries are approximately 60% lighter than traditional Lead-Acid (AGM) units, offering a significant weight reduction that bridges the gap between heavy lead-acid (30-50 Wh/kg) and lightweight lithium (120-300 Wh/kg).
- Industrial Efficiency: High-density capacity allows a single 12.0 kg StratoForse-24V pack to replace cumbersome dual-battery 12V parallel/series setups, drastically reducing deadweight in commercial applications.
- Operational Cycle Life: These batteries support up to 3,000 cycles at 50% Depth of Discharge, maintaining structural integrity and high energy across the entire voltage range.
