  1. I have a Partybox 310, which is new, the battery has discharged for the first time. Now, I tried to recharge, the led is blinking, but don`t want to increase. I measured the voltage, is 8.4 V, appears to be fully charged, but in application shows 1-2%. On battery, the speaker turn on and in 10 seconds turned off. I tried everything found on internet, nothing works. It seems to be a fault in one of these two boards – circuit board or power board (the battery seems to be 100%), but I don`t know which is. It is very frustrating situation, because I didn`t believe before that even JBL brand could have such big problems with the famous Partybox. Please let me know what do you think what are the solving methods. Thank you
