Gotta a question. It's so simple it's stupid... but I've gotten two different answers from two people who know a lot about stuff like this, just not my EVX2.

Got some lipos coming from HC. I was under the impression that I would be able to just connect them to the EVX2 (running a single Titan 775 motor on this Emaxx), and go. I have a choice between using a Novak Smart Stop 2s LVC on the BEC side, and I also have a 2S battery alarm coming.

The confusion is regarding whether I need a BEC or not, and whether I need to use a jumper.

If you look at this image, it implys all of the above! But the title of the page says "brushless motors", but the picture is of brushed motors. I'm not sure if it even matters.

If you select the Traxxas EVX, then you have no choice whether to run a BEC or not, and the same for an LVC.

Castle's BEC, according to their site, is designed for 3S and up. So does that mean that the 2s packs I'm gonna be running be ok and not need a BEC?

Bottom line... do I need to wire my system up like the picture says and order a BEC, etc... Or was my initial thinking correct? Oh, and I've never used an LVC or a Battery Alarm before. I'm assuming the alarm wires up the same way that an LVC does. And the reason I'm not using my Novak LVC, is because I had read somewhere that the cut off value for them was either too high or too low. Can't remember which. But the consensus was, they didn't like them. I paid like $4 for it on eBay (no reserve), brand new! No one else bid on it!

Thanks!
