The Tello drone has a good amount of flight time and is so much fun that one Battery is just not enough. Do yourself a favour and purchase an additional one or even two batteries. I would also recommend the purchase of a multi battery charger so the batteries can charge whilst continuing to fly. The batteries and a charger are extremely good value. Regards Brenton

Can’t charging with this battery, return it immediately after the first charge

Lucky I got the battery to make my drone works again

Tried charging, but seemed not to charge fully. Then drone kept giving error code 13, faulty battery voltage.

Good battery, battery charging hub for 2+ batteries is must have.
