One thing not obvious about the Deans is that you have electrical contact area on only one side of that flat metal connector!

You see two big, heavy duty looking metal connectors sticking out of the male connector, and it's only natural to think that you are getting electrical contact all the way around. But look at the female connector. Only one metal side contacts with the other. So the surface area for electrical connection is quite small.

Therefore the relatively low current rating (relative to a round bullet connector - like the EC5)

Knowing I'd be using Deans, no point of going big on certain parts unless you do it all the way around to eliminate the "weak link".
That is not nessarily true. Resistance in wire and connectors is cumulative and the entire length is not limited by the highest resistance section. Use of larger wire part also has the benefit of providing a larger heat sink to the smaller sections.

I like the power poles because with multiple aircraft I have the option of using them in series,paralell, or direct... with out rewiring anything... and have had no problems in 3 years using them..

Power Poles for 12 S?
I use power poles for all of my smaller batteries, and am familiar with making connections with the 30 and 45 amp connector parts.

I've been told by Castle Creations tech support that I shouldn't use the power poles for my T-Rex 700e with the ICE 120. Now I replaced the ICE 120 with a Kontronik Jive 120. But I'm using Deans instead of the power poles.

I would prefer the power poles, but are they up to the task of powering a 12S helicopter?

TIA.

Rob

Yes, they are fine with a 700e. I flew them on my Rave ENV and now on my 7HV. There is an earlier post where they were tested to 300amps. Deans failed before the Powerpoles.

The best thing to do is test out each connector with the ripple voltage logging enabled. The higher the ripple, the worse the result. If the ripple voltage exceeds 10% of the pack voltage, its time for a different connector. Or you if can shorten the wires, or change to a better battery.

Remember that neither the APP 45 or the Deans is anywhere close to the 120 amp rating on your speed controller.

You can either listen to people who have used PowerPoles for years and love them, or you can listen to Deans users who "heard" something from their buddy who's really good at flying Park Flyers that PP are only good to 30 amps. Or you can watch the test video of wires melting before PowerPoles failed.

Or perhaps you can try them some day.

Haha, that's just mean Gary.

I've yet to actually REALIZE any empirical performance losses with my Dean's connectors, from 3S-12S, and I seriously doubt I ever will...

just making a point at the other end of the spectrum from the parkflyer comment,..which I also found very humorous <G>

Al, if you don't notice any difference, as well and as hard as you fly the machines, then any difference is probably insignificant. I realize lower resistance is better of course, but if the difference in me re-soldering everything for a month is like 1/10 of a percent of power, or 3 seconds of flight time,..it's not worth it. I allready have excess power for the way I want to fly, and go 10+ minutes, so it's not worth the effort.

As have already said I like EC5's but on the other hand I've seen Matt Botos fly his E9 on 12s and her was using Deans connectors.

One would naturally think bigger machine requires bigger connector.

But, using the same capacity pack as a guide (5000mah in this case), regardless of the number of cells, the one that burns (flow of electrons) to the end faster will require bigger connectors.

So comparing 6s5000 at 3min(80%) (80a avg discharge) vs 12s5000 at 5min (48amp avg discharge), 6s setup can use more robust connector than the 12s setup.

Yet, most who use different connectors will opt to Deans on 6s while EC5 on 12s.

On our 12s setup below, full flight has been upto 6:45 to 80% which has onlly 35amp avg discharge. So with spark protector, Deans are more than sufficient to handle the job. The current range was such that old puffed 30c packed provided similar performance most of the way until the 30c voltages started to drop. On the other hand, I'm considering using EC5 on our 6s Trex 600 which runs little over 3min with no spark protection.

I use traxxas connectors, they're easy to pull apart unlike the deans and can let you solder 10AWG on them.

While I do and will continue to use Dean in foreseeable future, anyone starting out with 600 or 700 should consider EC5 or others. Not because Deans can't handle the current. But, simply there are better options available today and you do not have to resort to separate bullet to maintain the integrity of the Deans contact.

Partly because you guys aren't pushing it real hard, and partly because it's a NEU motor. Best efficiency motors I've ever tried!
What HS are you running btw?
