Designed for unique platform needs
Designed for platforms with specific dimensions, weight distribution or mechanical requirements.
/ Our high-density batteries
Custom battery packs
Our custom packs, with industry-leading energy density up to 450 Wh/kg. Every design is engineered around your platform’s space, power and weight limits and taken from prototype to series production.
Key advantages:
- Shaped to your platform
- Up to 450 Wh/kg
- From prototype to series production
/ use cases
When is a custom battery pack the right fit?
Some platforms need more than a ready-made configuration can offer. Our custom packs are engineered around specific space, weight, power and integration requirements to get the perfect balance of performance and fit.
Selected for your platform
Performance-critical missions
Optimize the battery around endurance, range, payload or demanding power requirements.
Deep system integration
Engineer interfaces, power delivery and communication around the complete vehicle architecture.
Field-proven at scale
See how we engineered a battery solution around a specific platform and mission requirement.
/ configuration options
Choose the right foundation for your custom battery pack
Every custom pack starts with your platform’s requirements. Our engineers select the cell chemistry and design the pack architecture around them, balancing energy density, power output and dimensions.
Power output
Built for the current your platform draws, including its peak loads.
Form factor
Hardcase or heatshrink, shaped to your battery bay to make the most of the available space.
Cycle life
Chemistry and configuration chosen for how often your platform flies and charges.
Durability
Tested to UN 38.3, including vibration, shock and temperature cycling.
Energy density
Up to 450 Wh/kg at pack level, for more energy in the same space and weight.
Materials
Aerospace-grade, lightweight materials, chosen to keep pack weight down.

/ development process
Partners in battery engineering
From day one, our engineers work as part of your team. You get their knowledge of cell chemistry, pack design and integration, applied to your platform and your mission.
Direct engineer access
Work directly with our engineers
Your team works closely with our battery engineers throughout development, helping technical questions get answered fast and with fewer handovers.
Shared requirements
Stay aligned throughout the process
We review electrical, mechanical, thermal and mission requirements together, so your pack is designed for the whole platform.
Collaboration
Collaborate at every step
Close communication makes it easier to review trade-offs, adjust designs and respond to new requirements as the platform evolves.
/ FAQ
Questions about our battery packs?
Are your products export-controlled?
Pending customer verification
Standard packs: [no licence required within the EU]. Packs for defence programmes are assessed per project and we advise on the classification.
Where are the packs manufactured?
Pending customer verification
Designed and engineered in the Netherlands; assembled in [NL and at partner sites]. Cell origin is documented per pack.
Are the packs lithium-ion or lithium-metal for transport?
Pending customer verification
It depends on the pack. Lithium-ion packs are shipped as UN3480 / UN3481, lithium-metal packs as UN3090 / UN3091. The classification is stated per pack in the documentation. VARIES BY CHEMISTRY.
Can I charge in the cold?
Pending customer verification
Not below [0] °C cell temperature. Charging a cold lithium cell causes permanent damage. Warm the pack first. VARIES BY CHEMISTRY.
Can the packs be shipped by air?
Pending customer verification
Yes, as dangerous goods with UN38.3 documentation and an MSDS. Air freight imposes limits on state of charge and packaging, which we apply. VARIES BY CHEMISTRY.
Can you deliver a European supply chain?
Pending customer verification
For [selected] packs, yes. Tell us the requirement and we state what is possible per cell.
