Man, I wish my Deans would come un-connected without my having to pull so hard I worry I'm pulling the wiring apart!! My 11 year old can't get them apart at times!

Yep I've heard that this happens with Deans.


These are polarized and if assembled correctly they stay connected really well.

They're slightly on the large side about the same size as Tamiya connectors which actually helps because there is more of the connector for you to hold onto when pulling them apart.

Ya luckily the turn marshal plugged it back in and i didnt do any more backflips for the rest of the race.

Anyone ever ran these??

I run those EC5 connectors on the lipo's I use in my truggy. They are fine connectors although the Losi version is way overpriced. You can get a pair at HobbyKing for $1.29.

Another good connector is the XT60's from HobbyKing. They are made to compete with Deans.

I dislike those red bullet connectors from HobbyKing. While polarized you can still take two lipo packs and plug them in to each other with those connectors. The XT60, EC3 and EC5 connectors are a better choice, IMO.

Unless you're smoking crack WTF would you want to do that?

I do see why some would pefer the XT60, EC3, EC5 etc but not because it's immune to pluging two batteies togther.

I do like the XT60 connectors only because they're more compact but my batteries came with the HK bullets so I didn't see a need to just remove what was already on a brand new battery.

With that said if I buy a battery from HK in the future that has XT60 already installed I may start using those for my new builds.

im using the xt60 connectors and they work awesome.....
they are real easy to solder and I like the recess for the shrink tubing

there is a thread around here somewhere by Ling, the ROAR battery guru,
he seems to like the castle 4mm bullet

The bullets are great but what if they get plugged in wrong. Then a fire or injury can happen.

+1 xt60

+ Doesnt have to be put together like traxxas

+ Wont burn your fingers while soldering like deans and no springy thing to deal with

+ Imo power poles are just as bad if not worse than traxxas connectors

+ Almost fool proof so you can't plug in backwards unlike bullett connectors


I read somewhere that bullet connectors offer the least amount of resistance though.

Murphy's law. If it can happen it will happen. A more realistic example with those red bullet connectors is when you are charging with the battery in the car. You could easily grab the ESC lead and plug your charger into the ESC if you are not paying attention. IMO, no reason not to switch over to a fool proof connector.

race prep! dialed in green lol.

deans here. never melted one, never had one unplug itself. have one or two that almost need to be pryed apart. No need fixing something that aint broke

The last time I read any articles on plug comparsion the voltmeter they used had to go down to .001 volts to tell the difference between plugs.

As long as the plug doesn't get hot or come apart I don't care.

I have been using Deans Ultra plugs since they came out like 15 years ago (mid 1990s). At the time they were the lowest resistance connector out there. I don't think that is true anymore.

The Sermos/Powerpole connectors are the red and black spring connectors that snap together and have been around forever. I know they were around in 1990 at least, and probably before that. There is nothing wrong with them really, they just seem like an old design to me.

The Deans Ultra Plug also has its weaknesses. They are kind of hard to solder. It takes a fair bit of heat to solder a 12 gauge wire on it, and leave the iron on a second too long and the whole plug melts. Weak!

I think the biggest weakness with the Deans Ultra Plugs are that the solder joints are exposed and have to be covered with heat shrink. The heat shrink is rubber, so it will degrade over time.

In theory I think the gold bullet and tube connectors that Orion and all the Euro companies sell seem like the best idea, except that you have to coat them with heat shrink tubing which can tear and will degrade over time.

I saw that somebody posted a link of those same bullet and tube type connectors that had plastic covers on them to provide insulation. That seems like an excellent design.

The other interesting option is the Losi EC3 connector. It again is a variety of the gold bullet and tube connectors, except the tubes and bullets are snapped into a plastic connector to provide insulation. The only downside to these is that it seems a little difficult to get the metal tubes to snap into the plastic parts. I have not done it myself. When I saw somebody else do it it seemed to take a fair amount of effort. There is also an EC5 connector that is basically the same thing, except it uses larger diameter gold tubes and bullets for the extra current in 1/8th scale cars.

Anyway so I was thinking about switching from Deans Ultra and will probably try one of the gold bullet and tube setups that also have plastic insulation on them.
