Battery Connectors

[Shark413]

I have been running Deans plugs on all my batteries for a while now. But I heard they are only rated for 60 or 70amps and I want to upgrade to something than can handle higher amps. I have some 5.5mm bullet plugs good for 150 amps and some 6.5mm rated for 200 amps. My question is how should I attached them as far as polarization? Females on the battery for both + and - and just be careful when hooking up the batteries, or male on the - and female on the +, or what? Any suggestions or anybody use bullets on there batteries and can share there experiences? I plan on making a non-conducting plug/cover for the ends to protect the connectors/batteries when on in use. Thanks.

I would be default put the females on the batteries. If nothing else, at least the positive wire should be female.

Only problem with bullets is I would be worried about accidentally shorting them against each other or something else. They dont seem very protected to me. Also depending on how you install them the possibility of accidentally hooking them up backwards. Take a look at the new Losi plugs. They are 5mm bullets with a nice plastic housing around them. I think they are called the EC5 connectors.

But seriously... I havent run accross a problem with deans and have no plans to change.

I ordered my self a bunch of ec5 connectors. They should be here in a couple of days. I can't wait to give them a try. Just need my MMM, soldering iron, bec and connectors to all show up.

Let us know how they work out for you.

The only thing I hate about the Deans is the difficulty in soldering a 10 ga wire to them .

[MTBikerTim]

That was my issue with the deans too.

Just after posting that last comment my EC5 connectors showed up and so did my Monster max (MMM was sent about 2 weeks ago).

Now I just need my bec and soldering iron to turn up but I can do without. I have a CC Bec and 3 other soldering irons I can use.

My CC Bec currently has a deans plug soldered to the end of it. I am thinking that it might be a good idea to keep it on there. I might split 2 wires off the MMM battery leads and solder a deans plug to them so switching out the bec will be easier.

Edit: I just noticed that the bottom of one of the packs of connectors wasn't sealed properly so all the bullets are missing. Darn losi's shoddy packaging materials.

Yeah those Losi EC5 plugs look pretty good. I ordered a set and will try them out. Thanks for the info.

[DRIFT_BUGGY]

Anyone know what the EC5's are rated for?

[MTBikerTim]

What ever 5.5mm or 5mm plugs are rated for. I can't work out if these are 5 or 5.5mm. Anyone know how they are measured?

I.D. of the female I believe.

I personally really want to try out the EC5 connectors. My hobby shop stocks the EC3s but obviously those aren't sufficient.. My LHS is lame in the fact that they offer almost nothing for cars but all of the crappy horizon RTR stuff.

If I can find a good price on the EC5s though I'll pick up some for my 8ight.

most of the boat guys run 5.5s they claim the same thing about the amp rating of the Deans, I have pushed twice that many amps through a Deans abd never had a problem. I do agree that soldering 10 awg wire would be easier to a 5.5

I have been running deans for years, used them in some real powerful setups. From brushed stadium trucks to my lehner 2250 powered MGM esc'ed twinforce. They have never failed me, never wore one out either. I have pulled 124 amps at 6s lipo and no failure to deliver power, I'll stick with them till i know i need better.

[BrianG]

We have to remember that even if our setups pull ~200A, it's only for a brief time. The average is MUCH less. Of course, the least amount of resistance is better, but unless you find the minimal voltage drop at really high current to be unacceptable, Deans are fine.

However, I do wish Deans would come out with a new set of plugs; something with a larger grip area and larger current capacity and still polarized/keyed. The regular Deans are good for smaller 10th scale cars/trucks for weight and size, but this is less of a concern in the larger 8th scale+ vehicles.

[Shark413]

Yeah after I installed my MMM with it's big bullet plugs and updated my ESC to Motor plugs to 6.5mm bullets the Deans on my battery seemed a little small. Never really had any issue with the Deans, other than they are hard to get apart. But with so many expensive components involved (MMM, Neu motor, Neu Energy lipo batt, BEC, FASST rx, etc, ) I figured having better (amp rating) connectors couldn't hurt.

[MTBikerTim]

After running my truck last night with the ec5s, I like them. Heaps easier to plug and unplug. Once I get them on my eagle tree and make a charge lead so I can charge my pack back up I'll see how many amps I'm running through them, not that it will say anything but it will be interesting. They are really easy to solder too I think. You just have to be careful not to get solder in the grove the housing locks into.
