Hey Jim, usually if you are venting a battery in a box like the part # AT89RR in the interior of a van you would want to run the venting through the floor of the van. So like straight down from the box. It really depends on the setup though and what would make the most sense.

Hey Jim, how did things go with venting the battery box through the floor of your van? Your results could help others figuring out the best setup for interior battery installs.

@JamesonC My understanding is that the gas coming off the battery is primarily hydrogen. Because this is lighter than air, I ran a small tube from the top of the battery box to a location slightly higher than the box on the sidewall of the van.
