MonoLith Battery Systems

800V Aerospace Battery Systems

High-energy density for hypersonic and eVTOL platforms

Hypersonic research platforms, next-generation eVTOL aircraft, and directed-energy systems demand the rare combination of ultra-high voltage (800V+) AND substantial energy density (30+ kWh). MonoLith offers 54 production-validated high-energy configurations spanning 705.6-856.8V, 30.2-51.4 kWh energy, and 353-600 kW discharge. This cluster is explicitly filtered for high-energy, high-voltage systems suitable for extended-duration missions where specific energy (Wh/kg) is mission-critical.

Aerospace and Hypersonic High-Energy Requirements

Hypersonic research platforms, high-altitude long-endurance (HALE) aircraft, and directed-energy systems require battery architectures that deliver BOTH ultra-high voltage for power efficiency AND substantial energy capacity (30+ kWh). This cluster is purpose-designed for this exact intersection.

This is fundamentally different from the broader 800V battery-pack market, where the majority of configurations are optimized for automotive fast-charging duty. This aerospace cluster explicitly filters for high-energy, high-voltage systems suitable for extended-duration missions, hypersonic testbeds, and propulsion systems where kg-per-kWh and specific energy (Wh/kg) are mission-critical parameters.

Specific Energy and Mission Endurance

At 800V with 30+ kWh per pack, MonoLith achieves specific energy in the 250-320 Wh/kg range-among the highest production-ready figures in the industry. For hypersonic and eVTOL platforms where every kilogram of battery mass directly reduces payload or time-aloft, this energy density is essential.

All packs undergo extended thermal cycling (-40C to +70C), vibration qualification per MIL-STD-810, and aerospace EMI/RFI hardening. Delivered with comprehensive DO-178C / DO-254 documentation pathways for certification programs.

Thermal Management and Power Density

Hypersonic vehicles operate in extreme thermal environments: external air temperatures range from -60C at cruise to +300C+ in leading-edge regions during acceleration. MonoLith 800V aerospace packs include active and passive thermal management: phase-change materials (PCM), integrated heat exchangers, and redundant temperature monitoring.

For directed-energy and counter-electronics missions requiring millisecond pulse duty (10-50 ms at full power, then cool-down), the 800V aerospace cluster provides unmatched operational flexibility. Custom pulse profiles and discharge curves are supported at NRE-free lead times of 10-14 weeks.
