Yeah I noticed that in the picture. That's probably because it's a 30C rated pack. On the higher rated packs they use 10AWG wires. They actually could've used 3.5mm bullets on those packs but instead they chose to use the higher current carrying capcity of the 4mm bullets. On some of the really high discharge rated batteries they have 5.5mm bullets.
At the end of the day it's not to save costs, it there to match or exceed the discharge capability of the battery.
My cheap $20 Turnigys come with 10AWG wires. Even the 20C Turnigys use them.

Why would you POSSIBLY keep 12AWG, 14AWG, and 10AWG all in the same factory along with 4mm, 3.5mm, and 5.5mm connectors? God forbid somebody installs 14AWG wire and Tamiya plugs on a freaking 60c 10,000mah 6S battery.
And to all the goofs that want to bitch about Deans plugs...it may be different in the high current world of gonzo 1/8 scales...but in your typical 1/10 scale 2 wheel low KV buggy or truck, you are unlikely to be pushing enough big power through those two 2" wide tires to really make a difference in what plug you use if you're NOT using Tamiya plugs. Get real.

Here is what everyone needs to start running. Easy to solder, I don't know who couldn't get a grip on them, should be impossible to accidentally(or even on purpose for that matter) hook up backwards, and plenty of current carrying ability.

$30+ per connector. No thanks. I will stick with deans.
There are lots of good low loss connectors out there guys. EC3, EC5, Power polls, bullets, Traxxas, Venom are all good connectors. Deans is still the most common and IMO the best due to easy of soldering, longevity and size/weight.

I never had a Deans fall off or come apart in a qualifier or race but I can't say the same about bullets, they loosen up with use and fall out, the "springs" flatten and they fall out. Reverse polarity, easy to do with bullets somewhat harder if not difficult with Deans.
Yes, you are correct bullets are superior in failure compared to Deans.
BTW 20 plus years ago it was Race-Prep connectors that were popular, Deans replaced those.

Also any person can unplug deans with VERY LITTLE pressure. Heck my balance charger came with deans and they're MUCH easier to disconnect than 4mm bullets. Deans don't wear out? Sure they do, all connectors wear out. Reverse polarity? Yeah if you're a moron you'd install the same gender bullets on each side...lol.
Only an idiot would use crappy Deans on a high powered offroad setup.

You took my quote out of context.
You said the quality of wire doesn't matter in such a short piece. My question is, why would quality not matter but going up a size would?

Because wire diameter makes more of a difference than some microscopic difference in chemical copper wire makeup. Take for example two 50 feet length of copper wire. One that is 10g and the other 12g. Lets say the 12 gauge uses a tiny bit "better" copper than the 10 gauge that's still not enough to make up the deficeit in the amount of current it can carry. The 10g will still be able to carry more current. The general rule is for every 3 gauges difference in wire equals doubling or halving of current carrying capacity...that is HUGE. In other words a 13g wire can only hand HALF the current of a 10g wire.

Haha Deans don't use a "spring"?

Yes it does if your battery can supply the current to take advantage of the 10AWG wire. Deans connectors have the same resistance as a certain length of 12AWG wire so it make no sense to use 10AWG wire with a Deans connector...lol. Now if you have say a 50C battery it makes sense to use 10AWG wire + larger bullets. Some bullets are rated up to 200A haha lets see Deans pull 200A efficiently...no way no how....enjoy your Deans.

Stop insulting people deans are more than good enough for the average joe, or even sponsored joe.

Yes Deans have a spring on them and no in 15+ years of racing I have never had a male (the side with the spring) fail. Never had one come unplugged. Never melted one down. Never plugged one in backwards. Tried a whole bunch of times but for some reason could never do it.
Did run bullets for a short time (lipo had bullet connectors in the case) and I caught myself putting the wrong wire in the wrong hole a couple times. I hate it when that happens!

Going by that type of monkey logic the Tamiya connectors would've been cool too since it also uses a *cough* large plastic heatsinked connector....lmao.
Sorry man plastic is not a good heatsink especially when the air is static and the temperature from the current draw is continuous, but you are free to delude yourself in thinking Deans are equal or better...lol.

who knows, maybe the tamiya connectors are even WORSE than they gave them credit for, but because they only measured the temperature of the external case, their results didn't show the true extent of how awful they are.
I'm not going to say I think deans are good or bad, because I truly don't know, all I meant was that I definitely feel that their testing method was flawed and therefore do not entirely trust their results. monkey logic my ass.
