The HXT connector is assembled incorrectly in both connectors. I've read complaints about this from people purchasing these from the international warehouse too. I had to tear these apart, desolder them, move the pins to the correct positions, resolder and replace the shrink tubing to make them usable. Not exactly convenient.Works great for charging my Syma X8C. The connectors the X8c comes with are not the greatest. I will probably switch out the X8C connectors to the XT60 when I get time.I purchased these so I could connect my walkera qr x350 pro battery, but the hxt connector is done wrong, there flipped and so cannot connect to my battery packs!!
