My batteries dont work


Hey.Sooo i have a problem i have kangertech kbox with aspire seems that it works fine until i place another battery in.The dots light up, shows how much battery is left.But as soon as i press the button to get a hit,the lights flash 14 times and thats it. I bought alot of batteries,with the tiny tip, without it,lipo,liion etc… Can someone help me to fix this problem?
