Low Battery

[aemkay]

Been out today and got a low battery warning on my 195 open. I have two batteries independently on a dual switch, used the new agm today, fully charged, battery meter with boat running shows 13.8v yet i get a low warning. what could be wrong?

The only proper way to know is to do a load test on the batteries. 13.8V is also the charging voltage so that won't tell us much.

I recommend you get them load tested.

Is of the heat? The rain?
I had similar problem. Voltage dropped quick on agm and connect dash shut off. 1 1/2 year old .
How long did boat run? Last time I had that error it took 5 min or so to go away.
