Default Benefits of 4mm tubes over deaans

I'm currently running deans connectors on all my batteries. Everyone else seems to be running tubes. what are the benefits of tube style connectors besides a cleaner look?

Deans offer slightly more resistance, are slightly harder to unplug (less surface area to grab), are more expensive. However, Deans are generally the de-facto standard being used and you can't do something stupid like accidentally plug 2 batteries together and short them for fantastic fireworks (and likely a hospital trip).

The dual banana plugs (red circles) as you see on a lot of things today are getting more popular as several cheaper LiPo brands are including them on the battery or the charge cables for them. They're easier to solder as well, since you do so outside of the case, then push the cables into the plastic...aka even if you suck, you won't melt the case.

I still use deans when I use a connector, though I'm moving more towards never using a connector and just using bullets directly on the cables from the ESC going into my batteries. This is less resistance than either, and less soldering to have to do as well.

If you want to do that, the way to make it impossible to reverse polarity (and cause giant spark shows and melted ESCs) is to make one of the lead wires shorter so it can't plug into the wrong spot on the battery. This only works with batteries that have bullet connectors built into them instead of cables though. Having an adapter around in case you need to borrow a battery or loan one out is always handy to solder up too.

^Good post. I always/only use bullets. It really cleans up the cars' wiring.

The only thing I would add is that to make sure your bullets are the solid type ones like these and not the "banana style" ones that bow out from the center and make much less contact in the female part of the plug.
