The Mauch 4-14S HYB-BEC Backup is designed to improve the reliability of a high-voltage drone. It is made specifically for the Pixhawk 2.1 through a Clik-Mate 2.0-6P connector and provides a clean, stable and redundant power source from 4 to 14S LiPo batteries.
The listing describes it as essential for industrial, heavy-lift and critical-mission UAVs that need the highest level of flight controller power security.
It is a hybrid BEC, which combines switching efficiency with linear-regulator cleanliness, and it takes over automatically and seamlessly if the main power fails.
Dedicated backup power: made for the Pixhawk 2.1.
4S to 14S LiPo input: high-voltage compatible.
Hybrid BEC: ultra-clean power.
Clik-Mate 2.0-6P connector: plugs in directly.
Automatic redundancy: seamless power failover.
Protection: short-circuit and over-current protection.
Compact and light: 54 x 21 x 14mm and 17g.
A flight controller such as the Pixhawk 2.1 (Cube) can be fed from two power sources at once. The controller uses the main supply while it is healthy, and a backup supply takes over automatically if the main one drops out, so a single failed regulator does not shut down the whole system in flight.
On large, heavy or expensive aircraft this redundancy is a basic safety measure. Use a second regulator that is physically separate from the first, with its own wiring to the battery, so that one fault cannot take out both sources.
Check both power ports on the ground-station screen before flight, and test the failover on the bench with the propellers removed, so you know the backup takes over as expected.
