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 ...

OK, yes, parallel batteries might do better separated. Series, no.
Remember, the discussion is about using two chargers. Trying to use two smart chargers for either parallel or series batteries never works well if the two chargers are in parallel.
Uh,..... need to tell that to my two PD chargers. I have a 55A and a 65A PD, one replaced the WFCO and the other is in the pass through.
For 8 years now I have often used them both in parallel to charge the 4 GC batteries wired in series/parallel when I have enough generator or shore power to do it. I get 110A for an hour or more into the bank, and then it tapers. quickly charges the battery bank.
And I don't seperate the batteries, just stuff the current to them. And the batteries are now 8 years old, probably 200+ discharges down to 30% SOC or more and doing fine.
Now if the chargers are different mfg, may be an issue. And I'm not the only one who has done this. IIRC there are several folks that have 2 or more of the great BD 40A chargers they use in parallel on batteries.
