i bought a traxxas 2-cell / 3 cell charger online and worked fine for a couple of weeks but then the 1st cell led went out, and had quit charging cell 1 no matter which battery i tried,so i bought a second charger of the same type and cell 2 led quit. i have no idea what is causing this, there isnt anything wrong with the batteries they charge fine on a someone elses charger, is there any way to fix the charger,im deployed right now and sending them in would cost more than it would take to get a new one
