There are a number of battery drawer installations that have been posted on the Forum.
I don't use this option since I have used other locations for my batteries.
Here is what I would be considering if doing this project: Some type of catchment for spilled acid and water from the refilling process. This could be as simple as a plastic tray or a dedicated battery box. Since batteries are heavy, I would use either ball bearings or inline skate wheels as the rolling mechanism instead of drawer slides. Guides could be made with a single piece of angle material. It may be necessary to reinforce the compartment floor. A tray stop so that the tray doesn't slide completely out unless I wanted it to. The same could contain the tray in it's transportation mode (i.e. not rolling back and forth). Adequate venting so that the hydrogen and sulfur dioxide can be displaced to the exterior when charging. If more than two batteries, I would probably choose an active system for this, i.e. a computer fan. Beyond that, the function and beauty is in the hands of the builder.
Good luck with your project!
