Oops, my bad
Total RPM was 60000 :)
In my opninion, the 2200's are awesome. They are 4/5 SC cells and put out up to 30A discharge.
Check em out at the gp site:

You can see the other gp cells here:

Here's my run down in weight comparison to the 3300's
The 3300's are 2.2oz
The 2200's are 1.41oz
The weight difference between the two at 20 cells = 15.8oz
I save myself 1lb by using the 2200's which is a huge difference in a race.
The 2200's give me around 13-14 minute run times which is fine for 5 minute heats and 12 minute mains.
I have to jump up to the 3300 or 3700's for the longer 15-20+ minute mains.
I am not sure how well the 2200's will work at lower total voltage but at 20 cells they're awesome.
