If you fly 3d foamies and other types of planes that use 2s and 3s lipos, then charging a lot at the same time is the key to getting enough flights in one day. This 6-plug parallel charge cable does the same task as a parallel charging board with six ports. The wires for the banana jacks are 16 gauge, while the JST wires are 20 gauge. All are expertly soldered and the soldering joints are beautifully covered with shrink tubing. With this setup, only one XH plug from one of your lipos will go into your charger's female XH port. This is a time-saver when you're at the field.
