I usually make my own 180 degree power pigtail, but BETAFPV designed the perfect pigtail for a fair price, had to buy them... I usually don't like BETAFPV BT2.0 pigtail wires, the silicon is high quality, but where you solder the wire right next to the wire is where it always breaks, I don't expect this to change :-(
I would recommend these excellent BT2.0 Cable Pigtails :-))))
