Connection Keeps Cutting off

My drone experienced a drop crash from about 10 meters, the housing was damaged and I started having connection issues. When I first turn it on the drone will fly normally but after around 30 seconds it either performs what it does when the battery is flat or the signals just cut off and the drone just falls. I have checked the board and nothing seems to be damaged nor disconnected. I'm not sure if it is the battery but when the drone does cut off I am unable to reconnect to it unless I disconnect the battery and restart it.
