Can you please give us a bit more information?
When you charge the battery do the green led lights flash and then stay on in sequence?
Do all the led lights go off when the charging is complete?
Has the battery been physically damaged in the crash (was it ejected from the Anafi upon impact with the ground)?
Can you tell us more about the crash, how far the Anafi fell and whether it is damaged?
If you put the battery in the Anafi and press the button does the Anafi turn on?
Are you able to measure the battery voltage with a multimeter?
