The Jeti Max BEC is a linear voltage regulator providing a power-supply for your receiver and servos. The output voltage is adjustable from 5 to 6V 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 better suited to 2S Li-Poly cells or 5-6 NiMH cells. The input voltage is indicated by four LEDs. If the input voltage is above 7V, all three green LEDs are ON. 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 goes ON indicating that cells are discharged (if using a 2S Li-Poly this means that the voltage of each cell is below 3.25V per cell).
For best results, ensure that the all BECs are installed at least 2" (50mm) away from your receiver and antenna.
