15 and 30 can be crimped without their special crimping tool, the 45's 'can' but one needs to be mindful of what they are doing and have some good crimping skills. The only difference is where the wire is crimped into the contact. APP's have a stainless steel leaf spring inside pushing the contacts together firmly, and are self wiping.Īnderson Powerpoles in the 15/30/45 amp varieties, all use the same size plastic housings, a 45 can mate to a 15. They are rated for 10K plug/unplug cycles, I would not trust SAE connectors for more than 200 cycles. Also SAE gauge cable is 6 to 12% thinner than AWG cables. Stinky plastic hot passing 25 amps for 10 minutes+. Many years ago, I made extensive use of SAE connectors on 10 and 18awg, and while many fold better than 12v ciggy plug/power ports, the bullet connectors in those plastic molded housings, wear out, then heat up, and become flakey. The + terminal on the battery end of the SAE connector should be enclosed/protected. Do label these as input or output or use some red electrical tape on the + portion, or both. I have found SAE 12v connectors to be inadequate, and one can unintentionally reverse polarity when an input is used as an output. Much better is a closed end ring terminal( no visible copper stranding) properly crimped and heatshrinked, and a connector on proper gauge wire/cable. Jaws properly set, often, chew up the post clamps whether lead or steel. The jaws of any clamp need to really dig in, to have adequate surface area to reduce point source heating and incurred voltage drop. Ideally, instead of the hinge pin and immediate surrounding metal conducting juicefrom one jaw to the other, there is a braided cable bridging the jaws so the far jaw can share the load much more equally.Ĭlamp on jaws are of course necessary and convenient, but any clamp on connection is only as good as the person positioning it on the battrery terminal and terminal clamp. These can exert many times the clamping force. Search for 'parrot jaw' clamps, rather than alligator.
