So I just finished my new DNA250 box, and it worked great. For about 5 mins. Now it will only work while plugged into a USB cord. Battery is not working at all. I have tried different batteries such as my MaxAmps that is in my currently running mod and those dont work either so I know its not the battery. Not sure what I should check. Just got the board today in the mail, and now its not working. I confirmed that the Battery wasnt hooked up reversed. I just am not sure what else I should check.
