I am laying the van up, and was wondering if the van is connected to 240 volt, does the electrobloc need to be in the ON position to keep both batteries charged .
<p style=”text-align: left;”>My advice is to turn everything off. Constant trick charging is not good for battery. Make sure its charged first. Check every month or so. Don’t forget to drain all water. Leave taps open and water pump disconnected.</p>
