Hydra 240 connectors.

[Sparky-rc]

Anyone come up with an easy way to solder the two # 10 wires on a Hydra 240 into a connector. I called Castle and they said to twist them together, solder as much as you could squeeze into the bullet (5.5mm), then solder the rest to the outside. Sounds a little funky. Anybody have a better idea??

the 6mm might be a littlre bigger

I have a few schulz 6MM connectors. The wire cup was actually a little smaller than the 5.5's. We'll be running nowhere near 240 amps (more like 80-100) so the 5.5MM should be fine. For the extra $50 I went with the 240 to be safe, but didn't consider the 2 #10 wires for each connection.

SOlder one wire in the cup and the other on the outside. THen just use a larger diameter shrink to seal it all up.

Thats what I did also. I cut about 3/4" of the silicon coating off each wire. Wrap wire #1 with wire #2. Taking care not to twist them. So when your done wire #1 is still straight with the #2 wire wrapped around it. You will end up with enough extra to stick into the connector. At this point I tin the two wires. Than tin the connector. Than solder them together.

Here is another example. These are bound tightly together with a sliver of brass plate, then soldered with a hammerhead tip.

After you cut your wires to length, if you tin the ends before you strip them, they are alot easier to work with.

I like that idea. Makes a mechanical connection also, which is nice.

Connectors

Has anybody come up with a method for the battery side using Dean connectors. If you don't use Deans then you have to change all your battery connectors.

Beautiful esc but those double 10gage wire are tough.

You can use the stated method above. But I would have to warn that the deans will get hot at about 60 or so amps. So you will not be able to take full advantage of the high amp 240 esc with deans. But it can be used sort of as an insurance if your running in the 40-70amp range.

Tell you what regarding Dean connector, here in France we've always been using bullet style connector, I understood that on the other side of the ocean, you guys are using more and more often bullet ones while (according to my local RC shop) we tend to use the Dean more and more often! Any logic in this?
BTW, I've change everything I had for the Dean style!... since I have my EagleTree MicroPower!

Some in our club have just used an entire Dean's connector on EACH battery lead, soldering the wire across both terminals. This works especially well if you are running batteries in parallel...

Interesting idea. Will this allow double the current?

Well... if the total paralleled system is being asked to deliver 100amps... each packs lead will be supplying 50 amps...

If you run the wires of each pack together through a single connector, that connector has to deliver the full 100amps...

So, I guess it will...

Brian uses the same setup, only with the 6mm connectors instead... The Hydras are actually set up quite nicely if you are working with a paralleled system... One lead for each side...

I have been assuming in this conversation that we are referring primarily to the supply side of the ESC...

On the motor side, I just shortened the two wires and soldered them to a single wire, then put the connector on that... I don't recall how Brian does it, but his way of going about it is very clean... I just "Y'd" the two wires together into a single wire at a three-way solder joint and put the contact on the single wire...

Having to go to all this trouble... I wonder sometimes if it wouldn't be a little more fun to drop the amps some, and get back to setups that only require single wires for all this stuff...

Darin could you please post up some photos of your set-up??

I thought the same, but I thought I read on RRR that this was not a recommended method by Castle. I could be wrong.
