Ask PYS: Power

Paul, on Aug 15, 2012 asked:

Does the battery monitor on my boat monitor all three batteries? It seemed to me last time that that batteries lost more charge than expected. What do you think of this?

Your battery monitor only monitors one battery bank; in this case your battery bank is composed of 3 AGM batteries. Your past experience with a battery monitor will not be very useful. This is because your battery monitor was used to monitor both engine and house batteries and didn't include the charge of the battery charger.
