The Jeti Max BEC is a linear voltage regulator for providing a power supply for your receiver and servos. The output voltage is adjustable from 5 to 6 volts using a jumper-plug. The unit provides a smooth voltage throughout your flight, resulting in smooth and predictable servo motion.

Max BEC can be supplied either by NiCd/NiMH or Li-Po/LiFe cells. This unit is best suited to 2 Li-Po cells or 5-6 NiMH cells. The input voltage is indicated by four LEDs and if above 7V, all three green LEDs will be lit. While the cells are gradually discharging, particular LEDs go OFF depending on input voltage (lower then 7V, 6.7V, 6.45V). If the input voltage is under 6.5V, the red LED comes on indicating that cells are discharged (if using a 2s Li-Po this means that the voltage of each cell is below 3.25V, so it will definitely be time to land!)

This BEC also includes a charging connector – it is possible to connect your charger and charge your cells directly in the model.


  • Input voltage: 5-16V
  • Output voltage: 5.0/5.4/5.7/6.0V
  • Burst current: 12A
  • Continuous current: 5A
  • Max. power loss: 7W
  • Max. temperature: 130°C
  • Weight: 25g
  • Dimensions (mm): 50×25x10

The recommended maximum input volage is 8.4V, e.g. a 2-cell Li-Po battery.

Always disconnect your battery when not in use.

Slight issue with telemetry modules
4/5 stars
By Barry Ensten
I have two of these regulators and use them with 2S lipos and they work very well. the LEDs are very bright, you can even see them through white film. I did find an issue when using it with a Spektrum TM1000 telemetry module. I connected the TM1000 to the charge connector and found the regulator wouldn't turn off! The Max BEC's switch is in the negative line, and the 0V connection through the telemetry module was bypassing it. The fix is to only connect the positive line to the telemetry module.

So only 4 stars because the fact the switch is in the negative line should be in the instructions..
