well i finaly got my new turnigy 3s 5000 batt's that i run in series for my L 500. they have made several new changes from the cells ohm's being matched to 10 gauge wire. with that said it was pain soldering on the deans. i am not realy sure in am going to stick with the dean's. i am thinking of just switching all my batts to bullets. but before i do that i would love to know what everyone is using to hook up there batt's.

power poles are nice, but mr mel recommends the 6mm bullets for lowest voltage drop.

these would probably do very nicely.

i use the castle creation 6.5mm bullets. rated to 200amps had dean and still do on the rex 500 but the amp draw on the logo so i upgraded only got 4 pack so wasnt much but still needed 5 packs with some extra. fit 10 guage wire great the 5mm bullet on the tp pack were tight IMHO

EC5's works fine too, that is what I currently using.

Voltage drop on one connector isnt that bad pretty much regardless of what you use, but if you start to have more then one connector (series connector etc, then you need to get something better)

Also, use this base; if your pack's wires have trouble fitting the connector, then it not the right connector for you.

I am personally not happy with HC's decision to use huge wire on all their packs. Their 2200s use 12ga which is just too big and heavy for 450s, and the use of 10ga on anything rc heli is just way overkill IMO. Plus the only thing you can solder it to is huge bullets. By comparison my new Hyperion VX 6s 2600 packs have 12ga and my 3s 2100 packs have 14ga, and they perform flawlessly.

Just as a note for those who don't know, the EC5s are just 4mm bullets (same size as banana plugs) in housing. I initially assumed they were 5mm because of the name until I saw one in real life.

As for my suggestion, I would use 3.5mm bullets. Either in a housing like EC3s or just bare bullets. The bare bullets are available on eBay for really cheap and work great.

Sorry man but the bullets housed in these connectors are 4mm to the best of my knowledge.

I know E-Flite says 5mm but they are the same bullets as these

Maybe they are measuring the outside of the female instead of the bullet?

No, they are REALLY 5mm, I'm sitting with a few infront of me and I can put a 4mm bullet female inside the EC5 female bullet..

Are EC3 connectors 3 mm? No they are 3.5mm. EC5s are 5mm though.

Probably the best connector available.

So Mr. Mel, what connector do you suggest for running 10s in series for my Logo 600? Thanks

EC5 or Bullets, I skipped bullets because I have small kids at home, a friends kids got hold of (even if they shouldnt) a pack, and what do a 5 year old do when they are holding two things that looks like they fit together?...

Here is how you can make the shortest possible Series connector;

If you find the price too steep for the EC5's, HC has them...

I just want to point out that many guys think backwards when they convert say a 6s 600 bird to a 10s 600 bird. They think because they are going to a higher voltage setup that they need bigger connectors. That is actually backwards. The higher the voltage, the lower the current for the same bird. In the example above the 10s setup only draws 60% of the current the 6s setup does. So the truth is that you can use smaller escs, smaller wire and smaller connectors. So sure the EC5 connectors will work fine for a 10s 600 but an EC3 connector is plenty sufficient.

Except the EC3 is too small for the wire to fit good since our 4x00 packs comes with 10gauge or bigger, its REALLY easy to get a bad solder and you end up with a lump of melted plastic in the field.

Been there, done that.

+ I peak 120 amp's on my L600, and at those amps, EC3 is on the short stack anyway.

Ah that is a good point. My 4s 5000 packs (ran in series as an 8s pack on my 600) came with 12ga and 3.5mm bullets worked great. I logged over 80A peaks and it never missed a beat.

120A on a 10S 600 would be 4600W+! That is insane.

Yes, for 12gauge EC3 is a good fit.

Nah, that good isnt many batteries, 34-35v during 120A peaks is normal for my Hyperion.

While we are on the subject of battery leads, has anyone found the Hyperion leads to be tough to solder? It seems as they have some sort of coating on the leads making them very tough to tin without a very hot solder iron. You can actually see the solder bead away from the wire.

Deans are hard to disconnect and difficult to solder heavy gauge battery wires. The contacts usually get loose in the connector if too much heat is applied.
I use Traxxas connectors, the contacts are soldered to the wire then they snap into the connector housing. This feature make it much easier to get a good solder connection.
They also will work with the 8 guage wiring on the Turnigy 6S 5000 pack.

The Traxxas connectors are rated at 150 amps and are much easier to disconnect than Deans.

I have had the same issue with coating on the Hyperion wires. I found using a acid flux gets the solder to flow in the Hyperion wiring.
