I am consistent.
I generally have to do things twice, or more, before I get it right.
Battery box:
The venting I have just will not work, first the original Montana vent is designed for one battery, second, there is only one vent hose. You need enough air volume to suck clean air into the battery box, and a vent to circulate nasty air out of the battery box:
Two vents. The reason there is just one vent in the original one-battery box is that where the cables come into the battery, the air gets sucked up from that air space. With a relatively tight top on my box, I got no circulation.
This is needed for two reasons,
Nasty air: explosive gasses, and cooling of the batteries, those suckers get HOT!
Another mistake I made is that the batteries need about 1" of air space between them, otherwise they won't get cooling air circulation.
Overheating shortens the life of the batteries greatly.
I have to re-do the cables I already made. Live and learn.....
