This switched JST connector is the best way to quickly prototype with our LiPoly batteries. We paired a genuine JST connector with a slide switch that can do up to 600mA. Both are soldered onto a breadboard-friendly breakout. There's two ground pins, one 'switched' power pin, and one pin that is always on. This is compatible with the "JST PH 2-pin" connectors we use in our battery packs.. Mates perfectly with all our 1-cell LiPoly and LiIon batteries as well as our 6V coin cell holder and 3xAAA battery pack.
