As others have said, running 4 CIM's shouldn't be a problem for a battery. The key is to monitor your current draw in testing, and any areas where it looks high at full speed you need to take a second look at - It means you probably have some unnecessary friction in your drive train somewhere (aka something is out of alignment).

Last year, we used two CIM's for a shooter. After the initial test and some adjustments, the current draw for those CIM's was cut in half!
