Just received the 5 batteries today and they are fine and a great deal for the $. They also sent a green USB charger with 5 ports as a free surprise which was a nice treat but it started to smoke as soon as I plugged it in! Be careful please do not leave this charger unattended! It will catch fire if you get a bad one. Looking at the board I really can't see a what caused it but the #2 charging port resister is fried and got hot enough to start melting the back cover which produced the smoke and smell that prompted me to unplug it. As with any cheap Chinese product always watch it closely when you first get it to be safe. I'm still giving a 5 star review because the product I bought (batteries) are great and work as specified.
I'm verry happy with this batetry pack with charger. I think this battery is more cappable then default battery from drone. If u look on the photo - standard battery wah 150mAh and this pack have 250mAh! So much fun!
