What Richard and Forest said is probably most sensible. That being said, my current class B with a 10.3kwh lithium battery has a separate alternator on the engine. When the battery is depleted it takes 60-90 minutes of driving to fully recharge. This makes sense for us since we drive almost every day which we didn’t do with the Newell. Still, it’s another option if you desire rapid recharging.
