The black one is the only safe one to use. It doesn't matter which way round you plug it into the transmitter, as positive is in the middle and both outer pins are ground.

The trouble is that some of the other batteries (such as the 1850 Zippy LiFe) don't include the black connector. People try to plug in the little white one (JR), which is only two-pin. It sort of fits but they get the polarity wrong -- poof goes the TX!
