The information here applies only to units powered with AGM batteries – it does not apply to Lithium powered units.
This varies depending on your situation.
This question is really about the battery life. Keeping it plugged in continuously won’t hurt anything, and will definitely keep the batteries charged. It’s important to keep the batteries full or near full all the time. If it’s summer and your rig is out in the sun, chances are the solar panels are keeping your batteries topped off so keeping it plugged in is overkill. If you live in a cold climate, you especially want to make sure your batteries are always fully charged. AGM batteries can freeze when discharged, resulting in cracking, and thus destroying them. Your choices are:
1. Stay unplugged AND power down the coach with the battery disconnect.
2. Keep it plugged in, and leave the battery disconnect ON, so that the batteries are connected and will be charged by the converter/charger.
The converter/charger in the Travato is a multi-level charger, and includes programming to condition the batteries daily.
