Has anyone seen this problem?

Battery 1 = Start;   battery 2 = House 

Small problem: The 4 LED Bars for the starter battery insist on showing the battery is fully discharged, despite 14.4v. I can reset this by draining the starter battery (really an AGM) and charging it, this will reset the LINK 20 to show the battery is fully charged (per the manual, this is the way to reset).  And then the problem just recurs.

Related Tiny problem: During each trip LINK 20 battery 1 is shown bleeding some power, proportional to how long I am using the boat. The + side of the battery only goes to the starter motor and the shore power, nothing else. Don't understand why the LINK 20 sees current as much as 12 AHr on a trip. When I go to charge the battery (shore charger) it accepts very little current before being fully charged. The LINK 20 then shows a deficit in the battery, do that a couple of times and the LED lights show one single RED bar.

Supporting information:

Starter Battery = 34Ahr;  House Battery = 125 Ahr; both new dual purpose (start/house) AGM batteries.  Alternator output connected to the house battery. Two bank shore charger, connected to each battery. battery Switch set to isolate start battery to engine starter and House battery to House loads. All bilge and other loads are on house battery.

I set the LINK 20 to the correct battery sizes; I used the other default settings, and confirmed they are at default.  I even went back and lied to the LINK 20, telling it the starter battery was 45 Ahr instead. No help.

Hi...i am a new user here. In my case i have done quite a bit of work on these and will be providing documentation on how to modify the settings, etc. along with a Linux driver. We expect to have all this ready to go by the time the piSmashers are ready to ship which shouldn't be much longer now.
