Having recently upgraded to Battleborn batteries, moving them into a small compartment in my MicroLite, I wasn't really satisfied with my mounting method. No, they weren't really going to move but it just didn't look good and the hold-downs were in the way.
It was bugging me as the job just didn't really look finished. Went searching on Amazon for a two battery tray that holds the batteries side/side without being an actual battery box.
Ran across this:
Ordered it and installed it yesterday. The tray JUST FITS two Battleborn 100 ah batteries. with both batteries in the tray there's not enough room to fit a business card between tray edge and battery side. Tray flexes just enough to slide them in.
Secured to the trailer floor with 8 #10 pan head wood screws and batteries are held down with a stout nylon strap with snap buckle rather than the traditional battery strap friction buckle.
Batteries are secure enough they will remain in position even if trailer was sitting upside down.
Now I'm happy. Install looks a lot cleaner than the punched angle/J-hook method I cobbled up at first.
Note: regular group 27 batteries (Maint Free, AGM,s, etc) are a fraction smaller than the Battleborns and will slip into the tray a little easier but will still be as secure. Strap is one-piece and passes under the tray which is well secured.
Just passing this on for any who are looking for ideas.
