I have two xt60 male conns with tails soldered on. Do you have any EC3 female connectors you can use?
Or I have a couple loose deans males that would fit your board. All you need would be solder and heatshrink .
Tell me if you want me to take these to the field tomorrow ( Tues )
Edit.......Ive made up the crossovers so it will be xt60 male by Deans Male ( to fit your board.
