The perfect 4x280ah box? Milwaukee packout.

Ive been searching last month or so for 2 solid boxes for the 2 4x272/280 banks Im putting in my van. Have been leaning toward tool boxes. New in my local home depot I spotted this today.
Its $60, which is a little more than I like, but the quality is equal to the cost so thats fair. Preliminary I.D. are, allowing for structural intrusions, 10.5" tall, 8.75" wide, and at least 13" long. Im going to purchase one and will update if there is much variance.
Its rated for 75 pounds. I also think the red color is appropriate for a power source. (Ive been a die hard Makita cordless tools owner for decades, theyre the best in their market segment. This may make me come over to the dark side)

Maybe I should change the thread title to the "maybe less perfect than this one battery case" because I hadnt seen this:

However the packout seems to have a little more vertical room and the lid has plastic reinforcements that I thought could be cut out if the BMS has to go there.

I like it. One thing to consider is the bottom might tend to flex a bit with that much weight. I would put some plywood on the bottom. But if you are not going to be moving it around much then it might be ok. I would also be careful carrying it by the handle. Some handles have been known to break off. Not saying the Milwaukee ever has or ever will.
