2 chargers connected to one battery bank?
Has anyone used two chargers connected to one battery bank? I have four (4) six volt GC batteries with 464 amp hrs. at 12 volts. The onboard "dumb" one stage charger is a 55 amp. unit. I just ordered...

Woowee I love some of these answers. I have had FIVE chargers working on one RV battery bank at the same time. Just don't let the voltage exceed 14.8 volts. And you do need to keep an eye on this.
Some chargers have a steeper charge curve than others. More voltage higher potential. What happens then, is the worker will keep digging while the less aggressive charger leans on its shovel.
Again, when it is costing a few dollars an hour to generator charge batteries, keep the voltage at 14.8 or less. Don't let it climb higher.
I remember one day on a beach in Mexico a know-it-all RV'er neighbor wandered over. He lusted for my diesel generator. "Say isn't that a lot of generator to be running just to charge the batteries?"
"Not really" I replied. "The last time I checked the charge rate was 310 amperes"
"Not possible!" he declared "No way are you charging 300 amps!"
I took him inside and introduced him to my 6" Triplett wall meter and the base for my kitchen table - A 300 lb adjustable ferroresonant charger. The meter on the charger was registering 200+ amps.
"The other chargers are adding another hundred amps" I declared.
He stared at the TRACE monitor. More than 300 amperes is big red numerals stared back. He staggered outside.
"Then I let the solar panels take over" I offered. I was using a Patton Whole House Ventilator 24/7.
