Mauch 083: 2-6S Backup BEC for Pixhawk 2


The 2S-6S Backup BEC for Pixhawk 2 is intended to be used as a secondary power supply in case the main power supply fails. The use of this backup BEC provides the highest level of power supply safety for your Pixhawk 2.1.

  • Optimized design for Pixhawk 2.1 flight controller.
  • Outputs slightly higher voltage to ensure Pixhawk selects the BEC as its power source. (PWM rail power sources ignored)
  • Input and output protected by high quality Panasonic FC / FM capacitors, preventing burn out of the UBEC from voltage spikes.
  • Redundant positive and negative wires (two each) to improve safety and reduce resistance.
  • Input reverse polarity protection.


  • Input: 2-6S LiPo (max. 28V).
  • Output 5.35V / 3A -> /- 0.05V –> Ripple 10mV (0.2%) at 1.5A output current.
  • 20cm output cable with Molex / 6p / Clik-Mate 2.0mm. (To connect to Pixhawk 2 / Battery 2)
  • 2x 20cm spare wires with Clik-Mate 2.0mm crimp, for Battery 2 current and voltage sensing.
  • Size: 47mm x 18mm x 11mm.
  • Weight: 9g with cables and shrinking tube.
