The Mauch 083 backup BEC provides flight controller redundancy and is designed specifically for the Pixhawk 2.1. This 2-6S BEC is a secondary power source that connects through the Clik-Mate 2.0-6P connector.
The listing says it automatically takes over if the primary power fails, offering a valuable layer of safety and reliability for critical drone missions.
It is a switching BEC (SMPS) with an output of 5.3V to 5.35V at 3A, and it includes short-circuit and over-current protection.
Dedicated backup power: made for the Pixhawk 2.1.
2S to 6S LiPo input: 7.4V to 25.2V.
Clik-Mate 2.0-6P connector: plugs in directly.
Automatic seamless redundancy: takes over if the primary source fails.
Stable, clean regulated voltage: 5.3V to 5.35V at 3A.
Compact and lightweight: 47 x 18 x 11mm and 9g.
Easy to install: simple integration.
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.
