Hi MIke

Thanks for a info. If I get this right, that Smartpass will charge until voltage goes up to 13V and then D250S dual continues?

I have VSR-relay on my boat. If I put only D250S and left my VSR-relay as it is, would that be working? I´m thinking to left VSR as it is and only add cable from start battery to domestic battery. Current will flow in some point different directions, but doesn´t that really matter?

G'day Sam,

I don't know much about VSR

If you search the web there is a very good powerpoint presentation about various installation options which I found very useful.

I chose to use both the Smartpass and the D250S Dual because they do different things. It took me some time to work that bit out - the CTek info isn't great.

Here is the document I was talking about...you don't have to search
