running two chargers

Here is a technical question. Let's say you want to charge your house batteries on your RV quicker. If you have two 12 volt batteries in your battery bank would you charge that battery bank quicker if you put two 25 amp battery charges on at the same time. Would that be possible to increase charging amps and less charge time or would it fry your batteries

If they are both smart chargers, separate the batteries and charge them independently.

Works best if neither one is a "Smart" charger.

That's fine.. with caveats. Two chargers may not work well together, meaning one may charge at a higher voltage and fool the other into thinking the batteries are charged. In that case, simply charge them separately.
