Todd good point. If you desire to run under the Hybrid label, you may
want a simple analog charger, unless you are using LiPo, or other
sensitive batteries.
Over charging is no problem, nor is slow charging, because you will
likely use everything the charger has to offer in moving the boat. Maybe
a relay to switch between the two chargers depending on the drive power
being on.
