3S 9L hpi mt2?

I've got three older polyquest packs, all 2s1p (i'm guessing 1p).
7.4v, 3100mah, and 12c/16c

the only motors I have are my neu, and a feigao 540c 9l..
I'm thinking about rebuilding the packs into a 3s2p pack, and throw it in my hpi mt2 with the 9l.

so that'd be 75a and 100a peak, do you guys think that'll suffice with the 9l in a 1/10 4wd stadium truck? the motor has a 3345kv, so it'd be similar to a 7l
