New board cutting off(please help!)

Hey, I have just tried my new board and found out the board is cutting power then going on rough terrain, it loses power exactly then I hit a bigger bump on the road, but I can’t make sense Wich part is bad, here is a picture, do you guys have any idea where the bad connection could be?IMG_20180705_163914

Besides for all of this connections you should probably take off the heatshrink on the batteries and take a look at the batteries. Also if you can pull out the electronics while still plugged in and spread them out a little bit and take a pic and post it

Very hard to tell from that picture where each wire goes.

It was the receiver plug! Hot glue and go ride again.
