I'm very satisfied
Item as described, quick shipping. Nice to have if you blow the main board on your JJRC Q65 by using 2 18650 cells at full charge instead of the 4.8 V NiCd that comes with the car. At a partially charged 7.4 Volts, Li-Ion worked fine. The car almost became slightly interesting. Things just ran a little hot. A freshly charged 2s 18650 pack at 8.4 V, on the other hand, will blow the board after about 3 seconds.
