These are wired up BACKWARDS! At least the ones I received were – the opposite polarity to every lipo battery I’ve ever bought that had a JST connector on it, and every model I’ve ever bought that was made to be powered by one. I used the first one of these today, to add a power lead to a project I’ve been working on for weeks – and totally destroyed it. I’ve spent the rest of the day trying to de-solder components, to rescue what I could. These have been the biggest waste of my time, my patience and my components. If I could give a lower score than one star I would – about minus one thousand seems fair.
