hi, I got my son a Potensic Firefly drone for Christmas and after a week we are having trouble charging the 3.7v 180mAh Li-Po batteries, we have been using a USB cable which was supplied but the batteries only hold 30 seconds or so of charge. At first the recharge time was about 30 minutes but now it only takes 10 minutes before the LED turnns green. Is there anything I'm doing wrong or any tips on bringing new life to them?
thanks
Andy
