Lithium or AGM?

[Perry Butler]

Yep, nothing to worry about. That's why ABYC and others require AGM batteries to be installed in a vented box:

yeah, and why cars like Mercedes come with AGM batteries that have vent tubes connected

to be fair, the larger car sized AGMs usualyl do have vent tubes, at least the H series euro batts. its the smaller motorcycle sized batteries that get sketchy

I stand corrected!

Enjoy,
