Bolt cutters are for... cutting bolts! sure you can use it, but you'd better get some extra crimps and make sure you have some additional slack on the power cable too, because I am positive you'll cut the crimp through completely the first couple of times. Also, even if you don't cut through completely, you'll be slicing the crimp, generally not a good idea. Get or rent the tool, a CRIMPING tool.
