High-density batteries for mission-critical unmanned vehicles

/ Drone power specialists
Gain 30–100% in range and endurance, engineered around your platform and assembled in Europe.

Most unmanned vehicles never reach the range they were built for

Your drone is only as good as its power source

The cost of low-density

Low-density power has been the industry standard for years, with off-the-shelf packs stalling at around 250 Wh/kg.

But think about it: you’ve optimized everything, from airframe to propulsion and payload. So why is the power an afterthought?

No single component moves range and endurance more than power. Until the power changes, your drone performs below what it was engineered to deliver.

Four ways to power your drone

Battery packs

/ The high-density standard

High-density packs, proven across the drone market and available now. The fastest way to upgrade your energy without changing your vehicle, ideal for starting or scaling operations quickly.

Custom packs

/ Built to your form factor

The same high-density performance, built to fit your platform. When an off-the-shelf pack doesn't match your form factor, we shape the pack around your vehicle instead of asking you to redesign around ours.

Smart battery packs

/ Own every variable

Fully managed smart batteries built around your platform. On top of high-density and a management system, they regulate temperature and charge and stay mission-ready for months, for operations where the pack has to hold up in the field.

/ how to work with us 

Book a call

Start with a short intake with our technical sales team. Bring your application: the energy density you're targeting, your form factor, your volumes, and your timeline.

Book a call

Get your offer

After the intake, we map your options and send an offer with the full pack specification and pricing. Once the order's confirmed, your project moves straight to production.

Your build begins

We plan the project, source and match your cells, and build each pack to spec. Every step is logged as we go, so nothing about your build is a black box.

We prove every pack

Every pack is validated individually: voltage, internal resistance, DCIR uniformity, capacity. It passes or loops back, and ships with its own datasheet. Then you prove it against your own numbers.

Shipped and backed

Each pack arrives in UN-certified, transport-safe packaging, with full compliance documentation and end-to-end tracking. Our team stays on for support after delivery.

Understanding your mission is the first step

/ Work with our experts
No two unmanned systems are the same. We work as an extension of your team, learning how your platform flies and what your mission demands, then engineering a battery around it, together.

Our client successes

/ Proven performance
  • 60% more battery without a bigger drone

    Lobster Robotics needed longer dives without a bigger hull. A high-density pack built on self-fused cells delivers 60% more battery life at the same size, and stays serviceable offshore.

  • A Leap in Flight Time Performance

    The Acecore Noa now flies 77 minutes at 1 kg payload and 57 minutes at 6 kg. A 39 Ah lithium-metal pack at 360 Wh/kg and around 600 cycles, retrofittable to every Noa already in the field.

Tulip’s R&D methods

/ From design to deployment
We design every pack around your application, selecting the ideal cell from thousands across 50+ suppliers, or building a custom one tailored to your needs.
design & simulation

We model performance on your platform before anything is built. Designing for manufacturing from the start means production takes shape while you test.

Rapid Prototyping

Your pack should run reliably, every time. To prove the design, we run fast iterations to reach the highest-performing, lowest-weight build.

Comprehensive Testing

Every battery goes through extensive laboratory and field evaluation, so it performs safely on your platform.

Production Scaling

The moment your pack is proven, it's refined, certified to UN38.3, and produced at volume: up to 100,000 packs per year per product.
