4 pin connector for the Parkzone/Horizon AR6400 and AR6400L brick

Also used on a Parkzone Green-Dot-Vapor-Brick with the 4-pin X-Port connector added
The term that's starting get used for these is NANO-JST.

It is wired with 5" of 32 gauge individual wires - you get all of the same color (our choice of yellow/white/red/black/brown) because the pinout of these are still unknown. You will have to figure out what pin does what!
