Dual 6V Battery Box
I'm upgrading my sons 5er from 2 12V batteries to 2 6V located in the front storage compartment. I'm looking for a reasonably priced and lighter box vs the heavy duty, heavy and high cost ($65+) ones....

is there a monitor for the battery gases like a propane monitor.
Unless you have a really abnormal charging scene, the amount of hydrogen produced is very small and is easy to vent because of it's weight differential with air. I did a bunch of searching and calculating when I built my 2-6V box. Mine is vented with a single 3/4" tube to the exterior. The chrome vent cap on the exterior has a diaphragm to prevent backflow of air. A couple of small holes toward the bottom of the box allows for air displacement.

Full view of box:
This box is lined with FRP plastic and has a gasket seal below the lid. It seems to be holding up well. Cables exit the bottom of the box into a 2" ABS pipe. The pipe is hung underneath the trailer and exits into the electrical distribution cabinet on the opposing side of the trailer. Total run to distribution bus with 1/0 cable is 6'.
