I am a little puzzled by your 0.4C requirement. That is too high for AGM or FLA batteries and will cause battery overheating and premature failure. Only Li batteries should be charged that fast.


If you drop to the recommended .25C max then two 1/2" belts should be ok at .25*900= 225 amps max. At that much load on two belts, just keep an eye on belt wear and tension. That approach is a lot cheaper than serpentine belts and a new alternator mount.
