ok pack
bad charger
do yourself a favor, and buy a proper charger to replace that crappy one that supracing says is a "smartcharger"
his charger will just blow your pack up.
though it's a bit expensive to get a good charger, the good charger will last well past the time when the li-po pack has lost all its punch (that's like, a few years.) and it's the only li-po charger you'll ever need to buy.
here's a link to a decent one:

and the required power supply:

charge on 1Aor .5A
2A seems too high for supracing's cheap cells to charge on safely
