I don't know if this is posted in the right area I apologize if it's not, but I just bought the phantom mech mod and it's making the top and bottom of my battery turn a little brown not badly but there is brown spots now I've tried flipping my battery to make sure the positive and negative is touching the right areas. Does anyone know why this could be happening and if it'll destroy my battery? I already had to get rid of a set of batteries from sparking in my rx200 lol don't want the same thing to happen. Thank you!
