I have a 4in1 Mini 3-5S 20x20 Stack/Combo (F4 FC / 30A ESC) that came with XT30 connector. My question is, can I switch the XT30 out for a XT60 connector? The battery is a 4s/1550mAh that I'll be using with that ESC. Thanks in advance .
Sure you can and aside of the slight added weight, it should work fine. Of course the wires won't carry more current than they were able to before the switch but it does allow you to use the same connectors across multiple devices.
