Pre-Made Anderson Battery Cables
 
My team bought some of the new batteries that are approved for use this year (2007), and we need to attach some of the Anderson quick-connectors that come with 6 AWG wire, as supplied in the KOP. We are also getting an additional charger, so we will need the same Anderson quick-connector, but with smaller wire.

From what I have read so far, it seems that teams need to spec out the connectors themselves, order their own wires, and assemble them themselves. There is also some hardware required to get the ends of the wires securely attached to the battery terminals.

Is this really the case? Doesn't IFI or some other F.I.R.S.T associated distributor have these cables already pre-made? Or, does anybody have all of the parts spec'd out?

Thanks!

As far as we know, if teams want to have additional battery cables, there isn't a source for the complete cable assembly as was in the kit. Rather, teams do indeed need to purchase their own Anderson Connectors, cable, and terminal lugs.

For the red Anderson SB50 Connectors, we've had good success with "Helmar Parts," who sells these connectors for about half the price of any of the typical robotics suppliers: http://www.helmarparts.com/product_p/6331g1.htm

Who would have thought that lift trucks would use these connectors?

there is a little reason for this = most teams put their battery in a different orientation to the "plug-in" point, with the positive and negative wires being of different length, so a standard battery wire assembly is usually not feasible.

I think he means "where can I get the same thing as in the KOP", not looking for a standardized version.

We ordered the anderson connectors themselves from Allied electronics. They ran about $3.50 each or so. And then you get in the mail (got it today) a shiny new Allied catalog. :D

How are you guys attaching your 6 AWG wires to the MK battery terminals?

We use some copper screw connectors picked up for the local Home Depot. Typical connectors used to add heavy wire to power panels.

We get the red Anderson connectors from our local Grainger warehouse.
www.grainger.com

To ensure a secure connection, we crimp and solder; because the lugs & wire are so large, we often have a mentor do this with a torch.

To connect to the battery, you want something similar to:

They sell similar connectors at Home Depot.

The 50 amp Anderson connectors are available through Terminal Supply as are a variety of connectors for the battery terminals. As pointed out, the copper screw down style is available at most home centers, be sure to get the ones sized for #6 wire. As a reminder for all teams, when attaching this style connector to the battery terminals, they should be positioned on the battery so that the clamp is turned to the inside of the battery to prevent damage. You may also bend the tab of the connector at right angles to help use the case of the battery as protection for the terminal and wire. After all is said and done, insulate the entire connection with tape or heat shrink. This style of terminal can be soldered using a large tipped iron. Be sure to feed solder from the end of the wire as it protudes from the terminal and don't add so much that it is visible under the wire insulation. This will harden the wire and make it more prone to breakage inside the insulation.

Oh god how I hate those things.

There may be some sort of benefit to using the screw down type of connector, but I personally prefer crimp connectors. They stick straight out, which is nice most of the time, the wires aren't horribly bent inside of them, and they tend to look nicer. The screw-down types tend to only hold by half of the strands (the other half stays to the side of the screw, and tends to cause problems.) In addition, your freshman electrical guys are a lot less likely to have strands of copper sticking out of the side of a crimp, and it's a lot easier to heat shrink over a crimp. It's also fairly easy to solder a crimp for extra strength.

Maybe we've just never done the screw terminals properly.

I think they come premade in the kit because do not have the resources to crimp their own cables.

I don't know if this is the case for sure, it is just an assumption.

That's not possible with the ones shown in my post. The screw doesn't make direct contact with the wire strands but is forcing a plate down against the back part of the connector. Wire strands cannot get around or to the side of the plate.

These connectors are bulky, but in my experience it takes a lot less expertise to screw down the connection properly than it does to crimp and/or solder correctly. We've had crimps fail due to not being done properly and we've had way too many cold solder joints on large cables. In addition, soldering results in a stiff to flexible boundary condition in the cable. Flexing at this joint can result in the strands breaking.

Yep, we've never done them correctly. Turns out I've been sticking the wire in on the wrong side of the clamp. Man, do I feel dumb now.

Meat,
(sorry, but I wish I knew your name)
It is good to learn. We should all work to learn one new thing each day. This is yours, for today.

hey can someone post the URL for Terminal supply company becasue for some reason i've had trouble finding them. And I myself am in need of Anderson Contacts. thanks guys and girls!
