connectors

Hi

Just bought some of these for joining heavy cables on my amateur radio rigs in the car. They say they will work at 65Amp all day. Tony "On Your Bike" gave me the link. 5 x PAIR Of RC XT60 Lipo Battery Connectors & Heat-Shrink Plane Helicopter Quad | eBay

Certainly seem to be the answer at the right price.

Is it cold and wet out their or what!!!

You can also get them in Hobby King, it's out of stock now but will come back in stock very shortly:
Nylon XT60 Connectors Male/Female (5 pairs) GENUINE

Otherwise, you can get the 6mm HXT connectors:
HXT 6mm Gold Connector w/ Protector (10pcs/set)

They are cheaper, rated for 120A, so you'll have less loss.

Don't waste your time with the naked XT60s, get them with tails already on, from HK. It makes a huge difference to the ease of use.

I have used Deans connectors for years.

Ripmax Deans Connector Pair (X2) O-RAD/2 | eBay

I guess the contacts are not covered and you do see a spark if the power is on plus those ones first linked probably have a better grip.

XT60 connectors are about the best of the bunch but can be a nightmare to solder to 8 or 10awg wire. I even bought a big 100watt soldering iron but it still didnt help much. Then I found some solder with a low melting point of about 175C. This had a high siver content of about 4% and since then I found soldering so much easier and reliable.

All fine, but try to use them with cold, wet hands... I'm still looking for XLR's with at least IP68.
Best,

Have a look at the Neutrik style of plugs & sockets

Why on earth do you want IP68? That's a shallow submarine connector spec, rated for immersion beyond 1m and is totally OTT for an ebike.

IP65 is fine for bikes (water jet spray from a 1/4" nozzle at 30kPa and 3m from any direction, essentially spraying the thing with a garden hose and narrow nozzle). In fact even IP65 is arguably OTT, IP64 (water splashing from any direction at 80 to 100kPa, a bit like a garden hose sprinkler head)would probably be fine and many ebike connectors stand up just fine in practice with IP ratings lower than this.

Hi Old Timer,

For normal current draws I use XT60 and EC3 connectors, both do a fine job, but I prefer the EC3 for ease of assembly. Both are polarized and have +ve and -ve terminal markings.

The plug and socket can be soldered externally to the connector body then pushed into the holder afterwards and if done well it does not need heat shrink sleeving.

Video of EC3 assembly - it shows the connector being held with pliers - what I do is insert the one being soldered into the mating half and hold that instead, it stops the heat from dissipating from the joint - tip! wrap an elastic band around the pliers handle to stop the connector from moving while soldering.

To seal it wipe a thin film of vaseline inside the body before mating the final connection.

Whatever connectors you get, There's one important thing: It has to be absolutely impossible for the conductors to touch if you bring them together the wrong way round.
