How to prevent reverse ESC connections
 

I don't want to use deans or any other connectors any more. I want to use bullet connectors and connect the esc directly to the battery. But what makes no sense to me is both negative and positive terminals on the batter are female bullets. I have reversed the connection once before and fired my esc and I want to find a fool-proof way to prevent it again.

It seems like if there was a female-to-male rod we put in one of the bullets on the battery this would solve it. Does anyone make anything like that?

Or is there a better way?

If you're using a bullet style battery, some people mark the positive side with a red sharpy and use red wire and red heat shrink wrap.. it helps. I too have fried an ESC but promised myself i wouldn't do it agian.

no way to do it ..ITS ALL IN THE USERS HANDS..Red nail polish on battery for + and red wires on esc connections..

Maybe I didn't explain it well enough.

To convert a female bullet to male would simply take a copper rod that is twice the length as the female plug. Put the rod in the battery terminal. Then you would have one female (connects to the rod) and one male plug on the esc.

I was wondering if someone sells something like that or if there is a better idea.

a better way might be to put a permanant male-male bullet connector in one of the battery posts. Then on the esc side have 1 male and 1 female connector.

Or make the one end of the male-male post just slightly larger diameter so it's much more difficult to get in/out than the other side. This way it stays put when you are removing the esc plug.

Make one of the wires coming off your esc too short to plug in to the wrong port on the battery, if it can’t reach the wrong port on the battery you can’t plug it in wrong. This is assuming all your batteries have the same port layout.

The simplest and easiest way.

I looked into that but with a shorty pack you have a lot of options for battery placement. To facilitate those placements the wire cannot be short enough to prevent mixing the polarities.

Or simply pay attention .... wait that one is just too easy.It will never work!! Forget I even posted anything!

This.

And I bet you're the perfect one that never needs a marshal either.

The fact is polarity is non-universal among the battery producers. Depending on battery position the connection isn't always in the same location. Never mind, racing sometimes goes into the night and the lighting isn't the best. Or someone else could be tending to your car, etc, etc.

If paying attention was the solution just imagine how different our world would be. So I will forget that you posted anything useful.

What class are you running? I use shorty packs in my B4.1 and can push the battery all the way forward and all the way back and the positive wire is a bit to short to reach the negative plug on the battery no matter what. I guess I could pull hard enough to make it happen but at the point I'd realize I'm doing something wrong.

I have a dex210 and when the battery is pushed all the way back it's under the chassis brace so the plugs would have to go forward. At this point the connector for the short plug would have to become longer to reach on the other side. I'll look at it again but I'd like something a little more fool proof and I'm getting tired of deans (and other connectors). Also my kids use this car as well and are very eager to help (if you now what i mean).

I should be able to make a male-male plug w/ some copper or other material.

You will need to secure the male/male IN the battery. If you pull the male/male when switching batteries you could plug it back in the wrong port.

The cars I have using bullets I setup with one short lead, even though I do look it's just insurance in case I'm hurrying someday and don't look. A little extra hassle when wiring up but well worth it.
