Deans vs, Traxxas

[bigwaveohs]

I haven't been able to find a spec on the Traxxas high current connectors. I think Deans are probably good to 100A...any thoughts on the Traxxas?

[Rumdog]

Deans aren't much good over 60A. Not sure on traxxas, Why not just use bullets?

[kookie_guy]

bullets are your safest bet. The REAL dean's aren't much good over 60. If you get the fake ones off e-bay they are worse. Traxxas probably isn't much higher, if at all.

Finally went with EC-5's from E-Flite...

Traxxas is worse IMO.
● harder to plug/unplug, your fingers will tell.
● one time use. You can't get the pin out once inserted, that means you have to cut the pack wire shorter and shorter every time replacing the connector, and they DO NEED to be replaced regularly. Deans can be desoldered and replace with ease, for unlimited times.
● Traxxas is bigger than Deans. in tight spaces like the marine hull that means something.

◆ Bullets are good choices but you have to be careful not to make a wrong polarity, Deans and Traxxas offer worry free connection once properly soldered.
◆ Bullet contact relies on copper flexibility and durability, they will naturally get loose over time, so make sure they are made from proper material and check them often. Deans and Traxxas don't have that problem cos they have steel spring plates to push the conductors together tightly.
◆ Soldering Deans you must be quick to well control the temperature stress on the plastic housing. If it shows up any sign of melt or deform, throw it away and go for a new one. Bullets and Traxxas are metal-only during solder process that allows long soldering time.
◆ Traxxas doesn't require heat shrink tubing while Deans does, bullets too.
◆ Bullets need two plugging operations for each pack, Traxxas and Deans need just one, with ensured polarity.

That's some points I can recall for now.

Deans have a place for me, my crawler and tow boats.
Any reasonable current draw above 30A and I'll call in the bullets.
I draw just under 200A in my big rigger and that has 5mm bullets.

The notion of getting the polarity wrong with bullets baffles me.
I use female on the pos and male on the neg on the pack. My charge leads and Esc's are then matched to this protocol and all is fine.
There is no way that I can get the polarity wrong doing it this way.

I have a few different plug to pack protocols and they are all to reduce (or eliminate) the possibility of hooking up the wrong packs to escs or getting packs in series insted of parallel etc.

Deans have a place, I have no experience with Traxxas. Bullets work for me.
