-From the battery's point of view, alternator charging rates should probably be ≤0.5C, with 0.4C probably being the sweet spot.  So ≤80A for a 200Ah bank.  From the alternator's point of view, current should be limited to [[electrical:12v:alternator_details#current|what the alternator can comfortably provide]] under expected charging conditions.
+From the battery's point of view, alternator charging rates should be ≤0.5C, with 0.4C likely being the sweet spot.  So ≤80A for a 200Ah bank.  From the alternator's point of view, current should be no greater than [[electrical:12v:alternator_details#current|the alternator can comfortably provide]] under expected charging conditions.
 As the Battle Born quote above suggests, for average LFP banks and average cargo van alternators these criteria will often be met with no reconfiguration.  If the criteria cannot be met then we will need [[electrical:12v:b2b|DC-DC charging]] or some other approach to manipulate voltage and/or current.((diode-based isolator, dedicated second alternator, etc))
