The Jeti Max BEC 2 is a linear voltage regulator offering two power inputs for two 2S lithium polymer batteries or 6S NiXX, with a maximum output of 20 amps, a sustained output of 12 amps and a weight of 85 grams. The linear voltage regulation provided by this unit does not contribute to radio interference.

Max BEC 2 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.

• Voltage cannot exceed the operating voltage range of products; this will cause damage to the product.

Tail Servo Step-Down Voltage is ideally designed to step-down a voltage source of 6-7.4  volts that is outputted from any external BEC (battery eliminator circuit) down to 5.1 volts.

This allows an external 6-7.4 volt BEC to be used with digital servos that are not capable of handling 6-7.4 volts. The Step-Down Voltage is equipped with male/female servo plugs and is ideally used in series with the RC model’s  servo to prevent any harmful damage or overloading to your servo.

SPECIFICATIONS:

Height ----- 4 mm
width ----- 8 mm
Length ----- 12 mm
Weight ----- 4 grams

High power component to withstand current of up to 5 Amps continuous, 10 Amps peak.
Prevents harmful damage and overloading to the digital rudder/tail servo.
plug and play Easy installation

This New Backup Guard II is much stronger than its predecessor, with many new features as well!

One new extraordinary feature is the Charge Mode. This means that the Backup Guard II can charge up the Backup Battery, with balancing, while it is operating. Charging rate will be 0.5A. This means you will no longer need to charge the Backup Battery ever again!

The Backup Guard II is now only the “Power Board” and you can connect your own size of 2s Lipo with JST-XHR Connector.

The Backup Guard II provides DC 5V with 10Amp Output, which is enough to land the aircraft if the ESC/BEC has some failure.

The Second-generation of Backup Guard II has 4 LED that will indicate the status.

Charging mode.

BEC lower than 5.5V.
