I placed an order for 8 batteries for the BetaFPV because the two that come are somewhat scarce to fly. The product is wonderful, it works luxuriously and the batteries work great. The problem is shipping. I ordered it in November and it has arrived this month, almost 2 months until it has arrived, it is the only negative point I have seen.
Great battery. light and powerfull.
10 minutes on my HappyModel Moblite7
Batteries worked great and run my whoops well.
