“I use these connectors in place of the EC5 connectors on my 1/8 scale rc cars because the are easy to solder and the casing is much easier to deal with. So far they have worked very well. Every connector I've receive have the AMASS stamp on it which is suppose to mean it is a genuine product and the casing is made of high temperature nylon.”
“I am using these on a series wire to turn two 11.1V, 65C, 6000mAh into a 6S. The wire cover snaps on neatly, with no issues, and the solder connections are easy and solid.”
