The decision
Review the module, battery and aircraft controls as one installation. Backup duration and power-sharing behavior depend on that complete arrangement, not on the module's power rating alone.
Identify the battery’s role
In a tethered project, the aircraft battery may remain part of the power arrangement. Its intended role could include supporting the aircraft during a ground-power interruption or working with the tethered supply during changing load. The proposed function needs to be checked against the actual aircraft and module.
Start with the battery’s specification, its connection to the aircraft, the allowed DC input range and any power-management equipment. Include manufacturer documentation and the existing wiring arrangement in the integration discussion.
Separate four operating conditions
| Condition | What the review needs to establish |
|---|---|
| Normal tethered operation | How the module supplies the aircraft and how the battery is connected |
| Short load increase | How the installation handles transient demand and for how long |
| Ground-power interruption | What power remains available and how the aircraft responds |
| Connection or restoration of supply | How the aircraft and power equipment handle the transition |
These conditions should have agreed evaluation criteria for the assembled system. A feature listed for one module does not define the behavior of every battery, controller or aircraft used with it.
Do not size backup from the headline power alone
Battery capacity, usable energy, battery condition, aircraft load and the proposed response all affect what the backup arrangement can support. A module’s kW figure cannot determine a universal backup time.
If the aircraft manufacturer provides a defined power-loss response, include it in the brief. If the project requires a specific response or reserve duration, state that as a requirement for review and evaluation.
Distinguish a short peak from sustained operation
The airborne supply must be selected for the actual load profile. For example, TP-P1.5 has a 1.4 kW rated output and a 1.5 kW peak output. The peak figure does not turn it into a 1.5 kW continuous supply.
Record the sustained aircraft load, payload load and measured peaks with their duration. If a battery is intended to help with a transient, include that requirement in the complete power-management review. See continuous and peak power for the rating distinctions.
Bring the power-management questions into the quotation
Send the aircraft model, battery information, module candidate and intended operating conditions. Include any existing controller or interface that needs to remain in use. We can review the power-module selection and discuss the integration work around it.
For a complete proposed power system, choose listed ground and airborne components in Build. A battery interface or power-sharing requirement outside the listed configuration can be discussed as a project requirement.
