Search is my friend ;D I was just wondering about this and decided to search. Low and behold what comes up, but a thread with a description and drawing of what I need to do. Thanks for the indirect help

So, if one chooses to run a separate pack for their RX, say a 2S @ 7.4v, do you need a BEC? I've already bought one thinking that I would splice it into the battery lead, but now think a separate pack makes a bit more sense in my 600E/MH-6 scale build. What packs do you guys recommend? I suppose that it doesn't need to have a high mAh rating.

If you run a separate pack you need no BEC. BEC stands for " Battery Elimination Circuit". If your running 7.4v make sure your electronics can take it. You may need a reducer or voltage stepdown they are cheap. I would say around 2000 MAH battery but do check!

Thanks valkman. Your videos are great BTW. So, I'm looking at my BEC last night and see that it takes up to 50v input voltage. If I solder it to the input leads on my ESC as in the diagram earlier in this thread, in a 12S series configuration, if one pack fails, will the BEC still be able to draw current from the good pack, or in a single pack failure it is a total loss because of the series configuration? I guess what I'm trying to determine is if having a separate RX pack is more or less reliable than a 12s series config.

Never mind. It looks like CC recommends connecting to the first pack in a 12s setup, so that would negate any advantage of a muti pack setup. Looks like a separate pack it is.
