I have a 40AH deep cycle battery, weighing 18.5kg. 100AH deep cycle battery weighs 40KG.
18.5*2.5=46.25 6.25kg short
Is something seriously wrong?

this is for one only of each battery, just an approx scale up is this error significant. 6kg is a lot of lead plate, and much worse if it's an hybrid..No. The 'error' is pretty small and there will be some economies of scale. Simplistically, two 40Ah batteries will need 4 terminals, one 100Ah battery will need only two. There will also be savings with the case and internal connections and mountings.
