good day all,i have a mastervolt battery and charging system on the sailboat i am running.12 2v batts ,mastervolt charging controller that commands charging rates from both gens and main eng and/or shore power.sitting at the dock for awhile ,batts topped up what should be ideal resting voltage?i think the way it is now(27.4v) may be abit high.however when i shut off the charger the real resting voltage,start of a discharge cycle is 25.8v,i want to keep the banks fully charged so as to use all available amphours available.i have steering solinoids energized when autopilot is off that are hot to the touch and i have found a burned out coil.thats why i am asking.
so my questions,should i lower the float charge level by the charge controller? should i try to find 28v coils instead?not seeing any other problems but dont want to shorten the life of batts or make more trouble for myself.
thanks for any info.

25.8 no load, charger off is about right. Voltage while charger is on will vary depending on charger. 27.4 is ok while charging but in float it should lower

As to the hot solenoids I dint think they should be engaged when the pilot is off and certainly not hot
