Chris is right (again!). The Robbe battery is the one I use and it's proved very reliable and didn't require much in the way of re-ballasting. The important thing to remember is that those little brackets attached to the battery sides allow the battery to sit low in the hull thus keeping the centre of gravity low. This is an important consideration in a sub as the motor torque will cause a high degree of roll if you raise it the c.o.g too much. You could use your preferred set up but try and keep it low!
