I have been watching the minis series and I noticed that they use a JST connector for the battery leads. I need to make an adapter. What is the standard, JST male on battery or JST Female on the battery?
As has already been stated, a power source like a battery should always have the electrically female connector, the one with holes (aka socket, receptacle) . The electrically male connector, the one with the pins or plugs should go on the power consumer. For example batteries with XT60 connectors have female connectors (holes) and male adapters (pins) that plug into them.
Generally, connectors are sexed by they electrical connection. This is the only convention that makes any sense because that is the important thing to know.
However for some reason the little red JST RCY (aka BEC) connectors seem to be referred to by the sex of their sheathing. So the batteries with these connectors have "male" connectors and "female" adapters even though the electrically female socket, the one with the holes, is the one on the battery (or should be).
Hobby kink at least is consistent about putting the electrically female connectors on their batteries at least as far as what is pictures and what I have received but they call the XT60 female and the red JST RCY "male" even though its really electrically female.
I was perplexed by this and looked around and it seems that this cross-dressing is the norm for the Red JST RCY connectors at least in RC circles. Go figure.
No idea what you mean by that. The male end of that adapter plugs into the female XT60 connector on a battery and the ESC plugs into the female end.
I have no idea why they put a female (ie electrically male) JST RCY connector on that adapter for a BEC. It should be electrically female. Anything you should plug into it should have pins not sockets... So it's a badly made adapter imo...an example of why it is a bad idea to sex a connector by it sheath and not its electrical connection since whoever made it was confused.
