Charge them all the way up, write down the voltages and let them sit for 24hrs. If the voltage drops evenly between the cells you are good to run them. Go easy for the first run and see if it puffs. If not try a little harder. After a few runs you will be able to tell if they are ok or not. Check the voltage of the cells after the run when they cool down. If they are way out of balance you most likely have a bad cell or 2...
