Your current assumption is actually too low. A stalled CIM will draw 100A+ at 12V, assuming no resistance. So a four CIM drivetrain will be trying to suck down 400A or so if you floor it from a dead stop. The only reason it won't be able to is all the added resistance from the battery, wires, PDB, speed controller, etc.
