I am thinking of keeping the engine battery of the van topped up using a 10w solar panel while laid up for the winter. Could anyone advise if it is safe to do this via the cigarette lighter socket,(it is live with ignition off) or is it likely to cause problems with the electronics of a modern engine (Mercedes). The other alternative is obviously direct to battery terminals.
