If you lipo has droped below the suggested limit, just charge @ 50 mA untill the battery is in the correct range (ie. 6.0v+) Then you can charge normally @ the 1C limit. You may have taken some life from the battery but It should not be a "paper weight" by any means :fingers crossed: The only thing is you say theres a week before your charger gets in...I would definitly charge it sooner than that. Don't let it sit a week below 6v. IMO
