Biggest/Bestest 2S stick-sized pack that can do more than 100 Amp?

[SidewaysLS4]

I'm swapped out my Novak 5.5r motor in my buggy for a new Novak 3.5r, and I'm finding that those 20C 5000mah Reedy batteries I'm using are now marginal for that vehicle. The Eagletree logger says that the motor is pulling 100-110 amps, and the current batteries seem to swell a bit so I think it is time to go for bigger better...

While I'm sure that going 3s would be wiser for what I want to do with this vehicle, I already have the Novak setup, so I'm gonna run with it for now.

So what big 2S batteries fit the standard stick pack footprint (height isnt that important, just L & W). Something good that might be rated at say, 150Amp continuous with lots of MAH? I think I'm gonna avoid Maxamps from what I've been hearing, as I really need it to meet whatever specs the pack has with no surprises. What's good out there?
