Second Battery maximum dimensions

[chrsbe]

I wonder if i should upgrade my standard auxiliary battery with a Victron Lithium Battery Smart 12,8V. In 200 Ah it has the dimensions of 237 x 321 x 152mm. Will it fit? Has someone fitted one of these already? What's the maximum dimension that fits under the rear bench?

A 150Ah Amptron has been fitted, look here.

I put a 100Ah lithium in second battery location. By my measurements, the maximum battery size is roughly 15" x 7" x 9" == 381mm x 177mm x 229mm L/W/H
