it would also continue to operate if the alternator fails. Having a very high amperage drain on your battery if your alternator fails, in the middle of nowhere, would not be fun.
For those who want the peace-of-mind of knowing their dc to dc charger will not discharge their battery if their alternator goes off-line for any reason, a BI serves a very useful purpose.
For those who don't, it doesn't.
