MonoLith™ Battery Systems
83-180V Battery Packs
Marine propulsion, heavy forklifts, and sub-150V industrial systems
The 83-180V band bridges industrial propulsion and marine applications, where higher voltage reduces copper losses and enables efficient power conversion below regulatory thresholds. MonoLith™ offers 210 pack configurations in this band spanning 82.8-180V, 3.456-62.2 kWh energy, and up to 259 kW discharge power. These packs serve heavy equipment, tugboats, and mid-range commercial vehicles that demand both extended runtime and high peak discharge without exceeding standard safety or certification limits.

Marine and Heavy Equipment Propulsion
The 100V nominal platform is the sweet spot for battery-electric tugboats, research vessels, and workboats. MonoLith™ packs deliver the sustained power needed for anchor-handling and trawl operations while keeping weight and deck footprint manageable for retrofit into existing hulls.
Marine duty cycles demand superior cycle life and thermal stability in salt-spray environments. MonoLith™ encapsulation and monitoring architecture is optimized for marinized installations with continuous ripple current and high ambient humidity, ensuring 10+ year service life in offshore and inland waterway applications.
Sub-150V Regulatory Safe Harbor
Many jurisdictions (EU, North America) treat 150V DC as the threshold where extra-low-voltage (ELV) rules transition to stricter industrial standards. By keeping the nominal band near 100V, OEMs can leverage simpler certification pathways, reduce safety interlock complexity, and deploy systems with minimal third-party inspection.
This regulatory advantage is critical for agricultural equipment, compact mining vehicles, and specialty off-road machinery where compliance delays directly impact time-to-market. MonoLith™ architecture supports this strategy with certified cell assemblies and validated BMS topologies.
Industrial Materials Handling and Heavy-Duty Forklifts
Battery-electric counterbalance forklifts operating in freezer warehouses and outdoor ports require robust energy delivery across extreme temperature swings. The 100V band offers OEMs room to scale capacity without triggering industrial compliance penalties, while the available power range accommodates both rapid acceleration and sustained lifting under full load.
With many distinct configurations available, fleet operators can optimize individual packs for their specific duty mix-small pallet jacks leverage lower energy designs for 2-3 hour shifts, while heavy counterbalance units use high-capacity MonoLith™ packs for full 8-hour operations with mid-shift opportunity charging.
