battery charging question
In order to charge batteries more quickly and efficiently when dry camping, would it be acceptable to run the generator (Onan 4.0 KW) and use an external three-stage charger plugged into one of the 110V outlets? Under this condition, the batteries would be receiving a charge from both the onboard converter/charger and the external charger. I have a 2011 Sunseeker with a three-stage converter/charger.
I am not sure if this setup would overload the system or cause any related problems. If anyone is using this technique, does it result in a substantial shortening of the charging time compared to using the onboard converter/charger alone?
Any info would be appreciated.
