Battery connection

[Adsmalan]

I wondered if anyone can help? I am using a Vortex E with JR xbus and the instructions state to plug the bec power lead to the battery port in the receiver. The bec I have has two power leads where would the second lead go?

Any other port on the Xbus standalone receiver or you can put it into the Dpod or battery port on the Vx1e

I run futaba sbus on my helis so may be different, but my understanding of the two battery / BEC port thing was to send either one lead to the rx and the other to the FBL controller, or both to the FBL controller.

The issue with sending both BEC plugs to the receiver is that its the FBL controller that needs the power as its driving servos etc. By sending both BEC connectors to the rx and using a single plug from it to the FBL controller, only one cable is delivering power to the FBL controller and the servos. So there is no point in using both BEC plugs to the rx.

By using one BEC plug in the rx and one to the FBL controller, the controller is getting power direct from the BeC and down the xbus controller. By sending both BEC cables to the controller the rx will be powered from the controller.

On my heli, to be extra safe, I made a harness up. I spliced into the loom a plug that branches off to the RX, and then I broke the end of the loom out to two more plugs and plugged both of them into the controller

You can plug both cables into the Vortex, or one to the Vortex and one to the receiver. Either option gives you two power sources to the FBL and a better power supply to your servos. Electronically, plugging them both into the Vortex is the slightly better option.

On the Vortex, all of the top row of pins share a common power bus, so you can plug the extra cable into any of those ports (Dpod, RX, SV1-SV5).

Thanks for the replies. I would have thought Spartan would have covered this issue as some power sources have two leads. I did think two leads to the receiver with one lead coming out did not make much sense. I did not consider both leads to the Vortex as I wondered how the receiver would get its power. I might try one lead to each as suggested and see how it goes.

Attach one of them to the BEC. It provides two power feeds without losing access to the ports. Works with all FBL systems and you can plug anything you want there... the receiver, throttle or tail servo, etc.
