You want a 22 Volt/32 Ah pack???
Whatever floats your boat.
Since you are an experienced LiPoly user, I would think you would know what the perfered RC charger power supplies are, a used internet server power supply, avail. on Ebay or Amazon for cheap. I use a 500 Watt unit that even w/ 20% losses, will power the typical 300 Watt RC charger.
Of course, a 32 Ah pack being charged with a typical 300 W charger is going to take all day, so you might want to think about a duo, which probably is going to need two server PS's joined w/ the isolated ground mod.
Personally, I would bulk charge a 2 brick 1S/21P pack.
