if you don't know what this is then you need to watch my last video for all of you guys that do know what this is a question came up they said what if the reason why these contacts are getting hot is the cheap Chinese batteries right what if they're getting hot and then that's causing the contacts to get hot to which I said to myself I don't have an answer for that but I do have but I could do a quick test and figure and rule out that the batteries are not the ones getting warm at four amps so what I'm gonna do is I'm gonna remove the one module loaded up with different cells like you know brand brand name cells and then we'll run that same test that we did we'll try to load it up with about four-and-a-half amps and then see if the temperature rises again okay here are some testing okay these are the cheap Chinese sells let's try them first and see how much heat it's created three amps
