Let's talk about connectors

[mrdakota]

I'm looking for new sources for connecting these high voltage - high current power systems.
I'm pretty straight on the wire requirements, but the connector arrangement is a little limited. Most use the 2 pin Deans, me also as well for the batteries and ESC connections. I was using the 6mm stubby pin-socket connections for the motor but recently started soldering a direct connection instead.
The Deans style connector has been my favorite for many years but I feel that I’m pushing its capabilities. The Power Pole connectors don’t have a positive-enough connection for the, I call it the “Mains Power” circuit.
Further more do you think that leakage current might be an issue also as these voltages are getting over 50 volts?
Right now I’m toying around with a dual deans type arrangement to minimize voltage drops, but polarity risks are a bit scary.

I have been using diffrent traditional 5,5-6mm gold bullets, but they all wear in time, and specialy if you have 8+s setups with a controller without anti spark function, thats why im now shanging to the new Plettenberg 6mm gold bullets, it has a diffrent design, se pics in test below and you will understand.

I took a look at your link but I couldn't get a translation to help me understand the data listed there.
I'm following your 42% build and looking forward to some of the connections you are using.
You are a pioneer in these big electrics in my book!

Thank you mrdakota, there is not much to understand other than the Ohm rating and the actual design of the bullet, as you can se on the pic of Pletti 6mm bullets, the "spings" are located inside the female bullet, therefore protected against the current spikes/sparks one usally gets with no anti spark protection.

Another advantage i have noticed on the Plettenberg bullets is that they are easy to soldier, you can fitt thick wires in the bullets for solder... hard for me to explain, put for example in the LMT bullets there is no room for more than a 4mm2 wire to be soldered in a good way, comparing to the Pletti bullets there is room for 2x 4mm2 wires.

I have actually today installed the Plettenberg 6mm Bullets on my Predator 37motor and the Jeti SPIN300.

I've been using the 6mm connectors from Neu Motor..
They work great!

Tam Jets showed me have to use a resistor and have no spark..

I'll try and get a picture of the set up

And at $25 for 10 pairs shipped, that's just $2.50 a pair.

Good looking connectors above, excellent solutions.

Since we use our packs in a wide variety of aircraft, and need a common setup, we use Deans on everything. On high voltage setups, Deans need to be monitored and replaced at regular intervals. We do this, and have no problems.

Ok, Jocke
How do I purchase these "Plettenberg 6mm Bullets" to try?
I did a search on Google, but didn't see a source here near the Chicago area or stateside for that matter.

Icare (http://www.icare-rc.com/connectors.htm#6_mm_dia) has the Schulze 6mm bullets, similar to the Plettenbergs. I care seems to be the US place to get Plettenberg stuff, but I don't see bullets there.

[Jocke]

Contact Plettenberg and ask where the best place would be to get the bullets for you.

I've tried the Schulze 6mm bullets before and didn't like the fit for my motor connection. I soldered the wires instead.
I'll email them for more info, thanks.

How did you use the resisitor to get no spark??? :) maybe a sketch

[Ron101]

Tam set this one up..
I just did the same setup
works great.. you just make a loop soilder it to the side of the connector..
as shown in the picture

when your ready to plug it in hold the loop to the other side for a second then plug in.. no spark.. but you don't want to hold it to long or you could pop the resistor

hope that helps

Wow... Simplicity in itself. I have seen a lot of people put smaller connectors in parallel with the main power, but it always seemed a little over-engineered. I like this idea. Thanks for the pictures. I may have to try it myself on my next build.
