Unknow connector - help please

[docramage]

The connector shown in the attached photos is a 2-pin battery-power connector for a Walkera 2D Gimbal (used in aerial photography). I measured the pin separation at 2.5mm.  It is faintly stamped with the characters "83 XS". A google search has not identified it.

I would be grateful if anyone knows what it is - and even where I can get some.

Many thanks
