Holy Stone Spare Battery for HS440 Drone

No problem at all. I have doubled my fun time with this battery

I bought my grandson a Holystone HS440 drone after some research. He loves it but with one battery when it's dead the fun is over. Two batteries give you added flexibility.

Worked great

I spent $50 for this Holy Stone extra battery.I got it from the Holy Stone store online. I should have charged it right away, but I put it aside till I fired up my Holy Stone HS440D last week. I plugged this one in to the USB outlet. I started smelling smoke after about 30 seconds, and looked over and saw a nice plume of acrid smelling smoke coming from the battery. I immediately pulled the USB out of the socket, and was glad I hadn't walked away for a few minutes. I may have come back to the thing actually on fire, as some of these lithium batteries apparently doThis should be a warning to all, that you should never charge these lithium batteries unattended!So thank you Holy Stone, as I'm now out $50, and I still only have one 20 minute battery. Obviously poor quality control from a company that makes good inexpensive drones, that I thought had better quality products.

Great beginner drone. Very easy to use and to learn. Battery life while flying is about 45 min.

Very good

Compre esta bateria adicional para el regalo de navidad de mi hija apenas la puse a carga enseguida comenzo a oler mal saliendo humo de la bateria eso me da a enterder que no existe control de calidad ,pense en compra más adelante un dron más sofisticado para mi ,pero ahora creo que lo pensaré mejor con esta marca
