my thunder aC6 charger just gave out and the onhly one i have left is a blade cx2 balance wall charger and it does have a 11.1v balance charger port but im weary of putting my bettery in it so if anyone knows if it is safe to charge it with that little charger please let me know and if you know how long it would take that would help to thanks.

yes it will work for sure as long as the connector are the same. 1800 mah divided by 800mah = charging time in hours.
