With that motor you might not be able to use it. But there will be a big difference in higher c rated big packs. My buddy went from SPC 12c 8000's to SMC 9000 28c, E-revo with MMM combo. He was running 44 with the 8000's, hit 50 with the 9000's. I run the same combo, but went from Neu 7800 25c packs, 2 4s 3900's paralleled. I went from 48 to 51.
