Yes that's a flat battery if you have a split charger you can run the pump for a while with
the engine running to finish off a job.

But the battery in the back is connected to the van battery so it should allways be charging ?

Depends on mileage mate, will only charge while engine is running. Pays to top up (bench charge) your battery once a week imo as it keeps battery in tip-top condition.

Does the controller work O.K. with the engine running ?
