Thanks both.

On a boat? Must have been quite a large boat.

Thus far I've not managed to discover whether the three output terminals are separate or common. The connections on the previous charger were one 'normal' and 1 labelled "Starter 1A" which I assume was to overcome the starter self-discharge. Without proper knowledge I'm wary of connecting the starter battery to one of the terminals since it would rapidly get fully charged and presumably put the whole unit into float before the domestics are ready. On the same tack: I took one of the domestics home to check that the charger was behaving as expected. This is therefore fully charged. What effect will this have when I connect it back into the bank with the other three partially discharged batteries? Will they gradually equalise? What will happen when the charger is connected? Can this damage batteries or charger? Will it be ok to turn the charger on immediately or should I wait for the 4 batteries to equalise? Sorry, that's a lot of questions. It's possible I'm overthinking.

There's a little more info online but really nothing like what you'd expect from a company with the profile that Victron seems to have. Maybe I was supposed to spend time talking to some random sales person and they'd have told me all the stuff that ought to be in the manual but isn't. You know, stuff like installation orientation: you'd think there would be a 'best' way for natural airflow, or perhaps it doesn't matter. Either way wouldn't you want to put that in the documentation?

And I've just bought the exact same exactly the same complete with what is laughingly called a manual (maybe not EXACTLY the same - mine claims to be Smart). Three positive and one negative output terminals. "Manual" makes no mention of how these should be connected. Like many boaters I have one bank of leisure batteries and a single starter. Do I common two of the outputs or leave one unconnected? Does it matter? Is each output independent? Maybe there's proper information available online.

That will probably not work until we have a Green gubbinment.

Sometimes you might be looking for a better deal from your existing provider (such as telecoms). In that case phoning them to tell them you're changing provider can work very nicely. But I agree that car insurance isn't one of those.
