@kylesf hey buddy, I just saw your post ( http://forum.erlerobotics.com/t/power-issues-with-dual-power-module/2618/20 ) I have the same exact problem, and I would like to know how you fixed it and where did you get the cable from. I have the same power module, but not the cable that goes to the PXFmini (the cable I have does not fit into the pxfmini). I have searched for the cable on Amazon but couldn't find it. This is my e-mail email@example.com please contact me as soon as you can. I'd really appreciate your help.
P.S. I don't want to buy the cable from Erle Robotics due to the very expensive shipping fee.
