[RE-wrenches] Battery Box Construction

[frenergy]

Add to the list...I've had good luck with Grace roofing underlayment: 
tough and to a degree, self-healing, sticks to itself (and anything it 
comes in contact with) very well making seams secure, easy to find at 
building supply store, sticks aggressively to battery box sides without 
mechanical fasteners, experience has shown it resists acid.  As with 
other solutions, something to uniformly distribute the weight and 
irregular bottoms of batteries should be employed.
