Batt charging Q - PD9245; and adding solar
Greetings; I am trying to get my little Rialta up to speed for full-timing. And need advice/help on charging my batteries and adding solar. I have 2 27 group walmart marine/deep batteries - abo...

PD should seek and hold 14.4v. If trimetric is reading only 14.1c, well that 0.3v unaccounted for, somewhere, or indicating some inaccuracy somewhere.
Many people wire their trimetric's Shunt incorrectly. No wire can go directly to battery(-) terminal that does not go to the shunt. The only wires on the battery(-) should be the one from the battery side of the Shunt.
If the house battery is directly grounded to engine battery, nothing can be directly grounded to engine battery either as current can than also bypass the shunt.
Pretty much impossible to reach full charge in less than 5 hours with Lead acid, and 5 to 7 is more likely when the charging source maintains a 14v+ absorption voltage for the last 4 hours
