Was flying at a location and had no issues with the first battery...landed the bird and took off with the second battery and started to lose control of the bird. Was able to get it back but was a very scary flight. Healthy drones info is below - thanks for your feed back. Hoping to figure out what went wrong and how to avoid being in this situation again.
