So the battery box is all done.
The support bracket. The batteries weigh 100 pounds each.
This box goes into the support and bolts to it. This is the bottom side.
The top side is open for venting. You can see where the batteries go on each side. The bars that will go across them will secure them from bouncing. It's tightened down by the two nuts you see on the previous picture.
We got some work done on the bumper too. It's a bumper I originally had on my jeep, made from JCR offroad.
Cut it in half, and made it wider to fit the van.
And had to add another section underneath to comply with DOT bumper height requirements.
