Default 30cc Battery Setup Question

Hello all!
I have a quick question about the battery setup on my 30cc Edge 540. Currently I've got a two-battery setup, one 5-cell NiMH battery to the receiver for flight controls, and one to ignition. I've got a few flights on this setup, but I'm looking for a slightly more redundant system. I'm not too fond of the current setup as it offers no redundancy for flight control power whatsoever in the event of a battery or switch failure. I came across this as a potential solution: power the receiver with two separate NiMH batteries, each through its own individual switch and each plugged into its own receiver port. I would then power the ignition via a IBEC out of one of the ports of the receiver. Has anyone flown a setup like this? Is this advisable?
Thanks so much for any and all advice!
Malcolm

You are going to get a hundred different opinions, so here is mine. I have used the redundant battery set up you mention many times, over many years without any issues. 2 batteries, 2 switches, plugged into different receiver ports. But I don't and never will power my ignition from any battery connected to my receiver. I always use a separate ignition battery. Yes, that makes 3 batteries to charge, big deal. But a warning. You cannot charge the 2 receiver batteries at the same time. You will have to charge them 1 at a time. Go for it guys!!

A Tech-Aero IBEC will allow you to use 2 batteries for your receiver and power the ignition module at the same time. Perfectly safe and no interference issues to worry about.

Exactly. Have this setup on several planes and it works like a champ.
