The alligator clips are a bit on the large side, but has a very good grip and low resistance. They are available in smaller sizes for low-voltage applications to large sizes for high-voltage applications. The clip part that attaches to the terminal or lead wire on the alligator clip is uncovered.

It do have fairly many thin strands, making the cable flexible. Alligator clips and insulated clips are hardware products that clip on to and easily connect terminals and lead wires. It is not high temperature resistant, a solder iron at 150☌ can mark it, at 350☌ it will slowly melt the isolation. With my caliper I measured the outer diameter to 3.8mm. With 10A current the voltage drop increased from 1119mV to 1158mV after 15 minutes It looks like the maximum temperature increase is about 15☌, this is not bad for alligator clips at 10A I uses 10A current for 15 minutes before taking the temperature photo. This setup was used for 'Resistance' and 'Front+back 10A' column. To eliminate the contact resistance I can use both ends of the plug, this way I only measure the actual cable resistance. This setup was used for 'Front 10A' column. The red alligator clip supplies current and the yellow is used to measure voltage. I did one measurement that included resistance between socket and plug. The 'All' row is all five cables connected together in one long string, this means 5 times cable resistance and 4 times contact resistance (Alligator clip to banana plug). I measured ohm by using the 'Front+back' setup, this gives the resistance of the wire and internal connection to the plug, this is 20mOhm for one cable, this gives an estimated 18AWG or 0.8mm2 for the cable.

The wires are 95cm long on all cables measured from end of strain relief to strain relief on alligator clip at the other end (i.e. It is also possible to grip a 7.3mm threaded rod The alligator can hold a 24SWG (Ø 0.56mm) wire very tight and solid. The wire is soldered to the alligator clip, this makes repairs easy, but is not as solid as a crimped solution. The other end of the cable is an alligator clip, the spring is a bit tight requiring some pressure to open it. Other brands of banana plugs fit nicely into the back. The plug gave good contact in all the devices and binding posts I tested in. The actual plug is 16mm long and the thick part adds 1.6mm (My other plugs are 17.5 to 20mm long). The plastic bag do not list any specifications. GSC International 160458-R-12 Connector Cords, Banana Plugs and Alligator Clip, 12 inches length.
