I know a couple guys that have that one and its a good charger as far as a quality charge. But your limitation may be your power supply, and the max 150w charge rate as far as speed goes.
It with do a 12a charge on a 2 cell pack, but the 150w rate will be a limitation for 4 or higher cell count. You may see a max charge amperage of about 10a charging a 4 cell pack where you might see the max 12a charging a 2 cell.
Amps = Watts / Volts
So 150 watts/14.8v (nominal) for a 4 cell= 10.13 amps.
It will do what it will do and make sure your power supply can provide at least 120% of what the charger can ask for at a minimum. You don't want to max out your power supply.
180 watts, 14.5a and 16v minimum for the power supply. Voltage is a wild card, the higher the amps, the lower the voltage it will pull. Wattage and amperage is the most important in the power supply and the decent ones are 18v.

This was a brain dump... someone correct me if I'm wrong on any of this.
