JETI model Max BEC 2D, Manual, Page: 3 / 12

The Max BEC 2D can be powered by up to two batteries. These can vary by cell-count and
chemistry and the BEC will always take power from the battery with the highest voltage. If both
batteries have the same voltage, then the BEC will take power from both batteries together. LED
Batt. A and/or LED Batt. B will indicate which battery the power is being drawn from. This can
also be determined from the Jeti Box.
If only one battery is to be used, it can be connected to battery input A or input B.
To connect your device(s) to the BEC, either solder your wires (Please use wire of at least 1mm2
diameter or larger, depending on your anticipated load) to the MPX output connector of the BEC
or use the Jeti MPX/3xJR cable, available separately. The Duplex EPC receivers, such as the R6
EPC, R8 EPC, R12, R14 and R18 are already fitted with a compatible MPX plug.
3.2 Communication with the Max BEC 2D
3.2.1 Connecting to the Jeti Box
Connect the BEC to the Jeti Box using the red JR connector from the BEC. Plug this into the
appropriate socket of the Jeti Box (The socket marked signal, +, -).
Connect the power-supply battery to the BEC and switch-on the BEC using the magnetic switch.
For this setup, there is no need to connect a supply battery to the Jeti Box as it will be powered
by the BEC. There is no wireless data transfer in this scenario.
