Moving Trailer Batteries Inside with Vents

Tired of the problems with batteries on the tongue of the trailer, I moved mine inside. This video explains why, and how to vent your batteries as well.
NOTE Sept 2021: This video was made several years ago when deep cycle lead-acid batteries were the most popular type. Lithium batteries were extremely expensive at the time. No venting is required for lithium.
