I bought the Fatshark FPV kit for my first quadcopter,


and I am feeding power to the FPV power supply from a stand alone 3s balance lead connector that is attached to my PDB. I am currently using 3s LiPos, and I am wondering if I upgrade to 4s LiPos, do I need a new 4s balance lead connector to replace the 3s one I have attached to my PDB or will it run OK with the 3s connector.

Thanks! -Mason
