But 2 batteries plus an IBEC sounds good to me . Ohhhhhhhhhhh wait, that would involve more technology.

RCRON,
Whether you're familiar or not, a LOT of guys are flying with one battery, and quite frankly, it's not like you hear about a lot of them falling out of the sky.....
Maybe you know enough guys that have experienced problems flying with one battery, that have lost planes, to make you want to make a statement like that?
If we were talking about a glow powered plane, would you have the same opinion? Many have been flying those on one battery without incident for quite some time - even the largest ones?
I'm fine with the idea of you using as many batteries as you like. I'm just not real crazy about being accused of taking big chances or potentially endangering people because I fly with one. The technology to fly with one has been around awhile now.

Just last week I flew with one batt one switch and did not fall out of the sky........I thrashed my 540 3D setup to the max(high rates) landed and discovered I forgot to turn on the second Batt/switch.....sheeese this getting old is a Pain, but seriously the odds were still vary low of a switch or battery failure.
Good luck

Need some advice, will be converting 3 gas planes with EI to a 1 switch and I Li-fe battery system this winter, These planes were on 2 or even 3 switch and ni-cad battery set-ups before. However, I already have Smart-Fly opto kill switches in them. Can I switch to 1 battery for receiver and ignition without replacing the smart-fly with an IBEC? Is there some effective noise filter needed or even available to put between the battery and the ignition side of the smart-fly? I may just be confusing myself here?

Maybe you are confusing yourself, If this is the unit that you have ( Ignition Cutoff for Single Receiver Setups ) https://www.smart-fly.com/Products/I...n/ignition.htm, then I think you already have what you are looking for including the optical isolation, the specs for the ing cut off are, 4.0V to 8.5V, the 2 cells LI-FE batts are 6.6V and will peak to around 7.2V when fully charged.
If I was doing this, and I am because the Aero-Tech IBEC that I have on my Citabria can be regulated to 5.1V, 5.3V, 6.1V and 6.6V. I choose to keep it at 5.1V just in case the batt voltage drops, but I could regulate it to 6.6V to run stright from the receiver LI-FE batt.
If i'm wrong please someone correct me.
Thanks

Thanks for the reply, I know one of my engines ignition modules will require a lower voltage than the 6.6 to 7.2 of the Li-fe battery, the other two will be fine. My real concern is that if I use one battery with one switch that has dual receiver power leads (ED Ultra switch) then Smart -fly warns I will have a common ground lead back from the ignition module through the ignition side of the Smart-fly to the switch and receiver and battery. Is that only an issue if the module should fail, or will the noise from a bad plug overwhelm the 2.4 receiver? I think a lot of people have tried this with no issues, but what I understand of electronics ends at the on off switch and some companies this will be ok while others say NO!

A IBEC from Tech aero 2 123 battery and 1 HD switch from electric dynamics for that set up and don't look back
or if you fly J/R or Spk. a 2 battery R/X with a soft switch and don't look back R/L

Will probably go that way as the IBEC from Tech Aero and the cost of a second battery for the ignition is the same. May as well go the simple route, but that gives me 3 perfectly good Smart-fly opto kill switches I won't need.
