Generator for battery charging
Sorry if this has been addressed previously, however, I am wondering if there would be any problem with charging the coach batteries using a stand-alone 20 amp multistage charger that is receiving its power from the onboard generator (Onan 4K). I am assuming this approach would charge the batteries faster than using the in house converter. I also assume it would be advisable to disconnect the batteries from the coach circuitry to avoid any “feedback” problems that might be caused by the charger if this approach were used.
I would appreciate any advice as to whether this would provide any advantage (i.e., shorter charging time than with converter) and any precautions that should be taken.
