| wire gauge
Wiring up my crawler for 3s lipo and was wondering what would be the smallest gauge wire to use? Thinking 16 gauge but have read people using 12 and 14. Is 16 too small? Thanks in advance for your help. |

I match up the wire from my battery to the ESC. If the battery has 12g on it, I use 12g from the battery to the ESC. After that I typically use 16g.

I typically use 13ga unless the rig is smaller and lighter than my 2.2 comp rig. 16ga does work fine on a standard crawler setup, but gets hot with amp hungry motors.

I would use as big as you can fit within reason.....if you can fit 13, then do it....but don't make odd connections to your ESC if it can't take wire that big. If you are having wire heat issues, much more and a few other japanese companies made wire heatsinks....they look kinda dumb, but all my testing showed they actually worked. Heat sucks in electronics in most cases. Later EddieO |

Seems to be a lot of opinions (yeah I know what they are like). Appreciate everyone's input looks like I'll be OK with the 16 gauge or was that 1.5mm. Thanks again everyone |

An electrical system is only as good as the weakest link. That being said, if your batteries have 16 on them then 16 is all I would run. I use 16g deans in my berg with hh35t's and a 25c/35c 3s with no heat issues at all. My lipos have 16 on them. I know a couple of guys that run 20g and micro deans with 35t handwounds and see no performance issues.

If your going to use 16g wire, why bother to use high "C" rated packs? Try pulling 45C or even 20C through a 16g wire and post back your burnt up results. Doesn't make sense to me. |

In most of my rigs i use 12-14ga wire, and deans plugs. 16ga wire should be fine in most rigs. Just remember your wire is like a pipe it will carry more amps (water) efficiently if bigger. make it a water tower and its simple tank=volts (potential energy) pipe= resistance or ohms water flow=amps the larger the pipe the less resistance= less heat and more efficient flow. With that said, in a low draw situation, most crawling, a smaller wire should be ok, but in anything larger than a mini crawler i would like the ins. of at least 14ga wire. My.02 |

| I have been using 16g noodle wire with 45c packs and 35t motors for some time now. Nothing has burnt yet. I have even seen people you 20g with with the same batt and motors. Works great!

They boast about how soft it is and mention no chassis tweak at all, because their target audience is 12th scale pan cars. And mod motors. Telling ya, 16 gauge good wire is fine. | |
