cananyone tell me if this esc work ok with a 4s lipo without having to use a external ubec?

i know in that case i have to cut the red wire of the esc that goes to the receiver to disable the internal bec, but can i at least plug and play exactly as it comes to see if it works?
regards

dont bother chep rubbish
