Capabilities
From platform requirement to accepted pack
Six stages, each with the need it answers, the work it covers and what it leaves you holding.
01
Platform requirements
- Need
- You need a power system defined by the aircraft, not selected from a catalogue.
- What we do
- Mission profile, duty cycle, physical envelope, mass budget, electrical and mechanical interfaces and operating environment are worked through in order. Ambiguities are resolved on paper before they become hardware.
- What you get
- A signed requirement set that both engineering teams work from.
02
Cell choice and operating mode
- Need
- Endurance, power delivery, cycle life and safety pull in different directions, and the same cell can be two products depending on how it is charged.
- What we do
- We start from a cell whose specification we own, set the charge profile against the requirement, and state the trade-offs plainly — including where the requirement would be better served by something we do not make.
- What you get
- A documented choice, the reasoning behind it, and what it costs in service life.
03
Pack architecture
- Need
- The pack has to work electrically, thermally and mechanically at the same time.
- What we do
- Topology, current paths, thermal management, structural design and protection are designed as one system, with calculated margins rather than assumed ones.
- What you get
- An architecture package with stated assumptions and calculations.
04
Management, telemetry and protection
- Need
- The platform needs to know the state of its energy source in flight.
- What we do
- The management and protection strategy and the telemetry the airframe receives are defined, and the interface is agreed with the avionics team.
- What you get
- An interface definition and a stated protection behaviour.
05
Prototype and validation
- Need
- A design is a hypothesis until it is measured.
- What we do
- A prototype is built to the released drawing set and tested against conditions agreed in advance. Methods and conditions are recorded with the results.
- What you get
- A test record with methods, conditions and measured values.
06
Supply and service
- Need
- A programme needs the tenth pack to match the first.
- What we do
- Acceptance criteria, revision control, documentation set and handling requirements are agreed before production, and the history is kept under change control.
- What you get
- A controlled part number with a documented acceptance procedure.
ELITIUM manufactures the cells in the catalogue and engineers the packs built on them. This is how a pack programme is run.
What we can share, and when
Datasheets, test methods, measured values and certification status belong to a programme and to a customer, so they travel over a channel we agree with you rather than an open page.
The cell we make
21700
ELITIUM EL70
INR21700-EL70
6700 mAh · 50 cycles
A 21700 cell built for one thing: the most energy a gram can carry. Two charge profiles turn the same cell into two products — an endurance cell for missions where every watt-hour is range, and a standard cell for platforms that fly again tomorrow.
