Trimetric Monitor and Battery Charging Help
I have a WFCO 8930/50 Converter/Charger in my 5th wheel. On the WFCO website is states that it will not go into bulk charge unless the batteries are severely drained or some other maintenance issue. T...

Battery death sentence
Not guesswork. The WFCO snotrag is 101% sure to destroy your excellent batteries. 101% is pretty bad odds. I'll make fifty to one book on it and walk away grinning at the loser's expense.
I've done the following to a 55-amp WFCO. From a different power supply I passed 50 amps through the solid block aluminum heat-sink for nine minutes. I was foolish enough to not testing thermally before I touched it.
HELLO FIRST DEGREE BURN thumb and forefinger. The aluminum was at >400F
Say nothing about the cooling fan. The factory fan is obstructed and is near useless.
For finishing charging the most economical fix is to buy the 400-watt MEGAWATT
Set the EXTERNAL VOLTAGE ADJUSTMENT TO FOURTEEN POINT FOUR 14.4 VOLTS, USE 10 GAUGE WIRE TO THE BATTERIES.
and plug it into 120 volts AC.
When the batteries drop charging amperage to 3.0 amperes, the batteries will be happy. If charging with a generator when the WFCO falls flat on its face and charges less than 30.0 amps, shut it off and start the Megawatt. Add 2 hours of charging time every week until you get home.
For 1st aid at home connect the Megawatt for 2-days solid with your battery bank. Then disconnect. For pure rig storage, you may then want to connect a battery maintainer. Your reward if you deeply cycle those lifelines will be DOUBLE the battery life.
The formula for charged voltage is one half of one percent of TWELVE VOLT (six cells) total amp-hour capacity.
The above meets and agrees with Concorde's Lifeline operating manual exactly.
No factory charger or converter is preset to do this -- not even close.
