Quick Li-Po question

[supermaxx4190]

hey guys,
im thinking of making the jump into lipo. i just have a quick question. if i bought some 3.7 volt 4000mah lipo cells, how many will i need to have 2 packs of 7.4 volt 12000mah packs? the cells are rated at 6C continous and 10C max. so that would leave me with 72 amps continous and 120 max. would my 8L motor on 12 cells draw too many amps for these packs? the truck is 10-11 pounds geared 15/70. thanks
Isaac
