DCX3300
i have one and try to zap my packs at least once every 2 months.Even my new ones.Always zap as low as ur willing to go(deadshorted if possible). This will rasie the voltage and lower the IR without damaging the cell(NOT RECOMMENDED) . I have not been able to over zap a pack yet. I have a 1.15 pack matched by my buddy.(flatline racing producs FRP) blasted it at 97 volts each cell 3 times in a row while it was deadshorted all i can say is that is my best pack.(i got some 1.185 SMC at 30)they charge to 4700 and are uber ballistic. But...... i have to zap them once a month like that.
Just letting u know my experience.
