Follow all the AGM discussions on there. You may end up thinking twice.

Will the 55A alternator be sufficient or do I go with the 120A high-output alternator? After reading Don's old post in this thread, I'm leaning toward the bigger one.

These are internally regulated. Everything I've read says to use a multi-stage smart regulator to get full charge without damaging the batteries. My goal is to keep it simple, but the batteries are going to run $600-700. Do I invest another $300 in the smart regulator? And if I do that, do I need an alternator that is not internally regulated?

Thanks for the help!
