Jerry, what I've done a few times when my lipos are to low to charge is set the charger on Nimh mode and charge at 0.1mah and watch the lipo volts very close
if the pack is ok, it will come back up without issues.. when it reaches about 6v for a 2s pack I shut it off and put the charger back to lipo mode and charge the pack from there
hope that helps you....

Right on Jerry, glade to help...
Just make sure the volts don't go past 4.2v per cell, and keep a close eye on temp... if the pack warms up at all, good chance its done..
