ok so I just bought a kangertech subox mini kit today for my birthday. Worked amazing. I dropped it in my car only one time and it didn't even land on the carpet hard. The battery fell out and when i grabbed it to put it back in I noticed the side for negative. The metal button like thing. Is pushed in and I can't get it back out. Is there a way I can fix this I only had it for one day and I'm pretty sad about it. ;(
