Application area

Drones & Special Operations

Drone batteries are among the most powerful and sensitive lithium cells in mobile use — especially after hard landings or crashes.

Starting point

The starting situation in this area

RUK Li-Ion Safety Box – example placement in Drones & Special Operations

Surveying, inspection and security operations require short charging cycles at a high operating frequency. There is often little time for careful condition checks between missions.

Drone batteries are built for maximum energy density. They are discharged at high current, often put back on charge while still warm from landing, and flown close to the cut-off. That is normal operations — and it is where the cells are stressed the hardest.

Then there is the mechanical history. A hard landing, a touchdown in the field or a crash leaves damage that is not visible from the outside — the cell can become conspicuous hours later.

In surveying, inspection or security work the tempo is high and the charge cycle is short. Charging happens in the vehicle, in the operations container or in the equipment store, right next to the rest of the kit. Between flights there is hardly any time for a careful condition check.

How it works

How it works in practice

01
Check after the mission
After every flight — especially after a hard landing or a crash — drone batteries go into the box instead of straight back into use.
02
Recharge under control
Charging runs in the monitored interior, with continuous temperature control for high-energy cells.
03
Watch suspect batteries apart
Batteries that may be mechanically damaged stay apart from sound ones until their condition is clear.
04
Stay ready on the move
The box moves with the team to the next site — in the field, in the vehicle or at base — and keeps the same safety standard there.

Benefits

What the deployment achieves in practice

Designed for high-performance batteries

Suitable for cells with high energy density, as typically fitted in drones.

Controlled charging process

Reduces risks from high operating frequency and short charging cycles.

Usable on the move

Suitable for changing deployment locations in the field, in the vehicle or at base.

Safe handling after incidents

Enables separate, monitored storage of batteries after hard landings or crashes.

In detail

Typical situation, risk and solution

Typical situation	Risk without protection	With the RUK Li-Ion Safety Box
Drone batteries with high energy density in continuous use	Particularly high risk from mechanical pre-damage (crash, hard landing)	Separate, monitored charging point for conspicuous batteries
High operating frequency with short charging cycles	Little time for careful condition checks between missions	Automatic monitored charging during charging
Changing deployment locations (field, vehicle, base)	Permanent fire protection is usually not available on site	Mobile system for changing locations
High-performance batteries for special applications	Higher energy released in a fault scenario	Active containment of flames, heat and pressure
Training and operations centres charging several fleet batteries at once	High battery density while several pilots train at the same time	One central, monitored charging point for the whole drone fleet
Batteries after a crash or hard landing with no obvious damage	Internal damage is often invisible from the outside and stays unnoticed	A separate observation phase in the monitored interior before the battery is used again
