Default 11.1V vs. 7.4V Lipo--Stock racing

Could someone potentially use a 11.1V lipo to gain an advantage in stock class? If you had an 11.1V battery of the same physical dimensions as a larger 7.4V battery and removed the decals, would anyone be able to tell by just looking at them? Other than the obvious 11.1V truck would be faster, what would keep someone from doing this? Some ESC's can handle 3s lipos and a BEC could be used for the RX and servos. Maybe I should ask if there is a limit on battery voltage from the sanctioning bodies? IDK.

My friend and I were discussing this tonight and I didn't have much of an answer for him.

well for starters, most clubs and series dont allow 11.1V, so if you DO get caught with it, you will most likely be thrown out. plus why would you want the obviously unfair advantage? yes you could tell the difference simply through the balancer port. a 3s has 4 wires, a 2s has 3

There is nothing stopping anyone from cheating in any kind of racing. Unless you get caught. But to answer you question, the increased voltage of the battery would make a significant difference in how fast the car is, In return it would be very obvious that something wasn't right with your car and you would have people looking at you, and wanting answers. And like streetracer said, you can tell by the balance plug

OK. I don't intend to do this. My buddy asked the question and I didn't have an answer. Now, would a driver be able to "fake" the extra power by not using as much throttle. but still be faster where he wanted to be. I want to be the one who finds the guy that is cheating. LOL.

I enjoy racing way too much to cheat at it. The enjoyment I get from the weekly races with the guys is too important to me.

Yes, and that called sand bagging. Seen it done, and you can get away with it as long as you don't make it obvious.

Ok. Thanx for the comments guys. I'm sure someone will try this someday and post how there motor only lasted for 10 minutes. Or something like that. IDK. I was wondering how to continue the convo with my buddy tomorrow.

A lot of your newer speed controls and motors are safe to run off of 3s 11.1V lipo, and it wouldn't hurt them at all

The last time I check, neither the NOVAK, nor the LRP allowed more than 2s/8.4v.

It's very easy to tech, just need a voltmeter. If a LiPo reads over 8.4V, it's either being overcharged, or it's 3s. If it's being overcharged, and it's intentional, I'd ban that person from the facility.

Thanx guys. I was just wanting input on the situation. I didn't know how to continue the conversation this weekend when we will talk about it again.
