Have 4x 12v 28ah batteries sitting doing nothing. What is the best way to wire them in parallel? They are going into the van connected to either a 10 or 20 watt solar panel to maintain them until I can use the van again. Bill

I suggest that a "10 or 20 watt solar panel" is too big unless regulated.
5 watts would be plenty and 2 watts would be enough.
If they are AGMs they are good for at least 6 months with nothing, if disconnected from all loads.
Cheers,

Unless the loads are very high or the cables too small, most methods are OK.
The best method is the "star" method (google it) that involves taking equal length cables from each battery to a single point connection.
