Both are discontinued years ago, 2008 for link 20. Pretty dumb compared with whats available today.

Not quite. Xantrex went it's own way and Heart Interface remains as Heart Interface. The heart system is still pretty much mechanical/solid state. Relays clunk etc. Xantrex became all wizz bang techy solid state and have suffered for it.
The new brands of controllers like the Link have many new features, but how much info do you actually need. The Link system is still a very acceptable tool.

I think I will trace the wires on both. Make sure they only go to shunts and if so will replace with BMV712.

We cannot direct the wind but we CAN adjust our sails

Great pic ballystick!
Short circuit.
Was it internal or external?

There is nothing, absolutely nothing, half so much worth doing, as simply messing about in boats

Is it me or do those look like lithium cells? I see something looking like a cell link strap and the CALB yellow.

It was a local yachtie and I don't know the details but it was quite seriously worrying. Looks to have been a short somewhere so I was looking for suggestions.

Internal shorts you cant do much. External shorts is why you should have battery fuses.....

Oh, except making certain that your batts are properly secured. Crashing around can cause shorts. Non marine batts are not designed for the movement in a boat, and short more easily.

The battery was on a smart charger which was disconnected from the 240V supply and then the engine was started. A possible severe battery cell imbalance maybe?
