How close to each other can you install them, to be able to reach in and access the on/off and breaker on the side? The 12" requirement of the older model was pushing me toward server rack style batteries, but if only 3-4" or so required for these, they would sure be a space saver for our new build.
The manual recommends ≥12in separation between batteries.
