@philipeamanti use [https://www.youtube.com/watch?v=LqQOkRMsMWI|this video] to disassemble your Megaboom and replace the battery. Just because it sounds like it is fully charged does not mean it works. Batteries can be charged but lose the ability to maintain power when it is needed.Check the battery contacts and make sure that the charging port is still properly attached. Once you have a new battery installed you have a known-good starting point should further troubleshooting become necessary .
