had a 3s 2100 inflate, ballon... whatever ya wanna call it. after it cooled down the balloning went away, we took a reading and it was around 10.5V after a flight.........ok so charged it back up and it read 11.3 , so I put in a flight and everything went well. now Im hearing I should throw it away and not to trust it. I dont understand that??? if it charges up to over 11V and works in the model , then why throw it out??
