Just curious....Is there a requirement that batteries have to be in boxes on a boat? If so what are the requirements?

The ABYC Standards that apply to battery installation, Section E-10.7, are a bit lengthy. Call ABYC for the full details.

The main points, paraphrased and abbreviated:

Provide for containing electrolyte leakage or spillage (up to complete leakout), and isolate it from any boat structure that can be attacked by the electrolyte, including fastenings that secure the battery.

The battery should not move more than one inch in any direction (even upside down) when 90 lbs. of pulling force (or twice the weight of the battery, whichever is less) is applied for one minute.

Each battery terminal shall be protected from contact with metallic objects.

It may not be mounted above or below a fuel tank, fuel line fitting or fuel filter. Each metallic fuel line or fuel system component within 12 inches of a terminal or above the horizontal plane of the terminal shall be protected with dielectric material.

A venting system or other means shall be provided to permit the discharge of hydrogen gas released by the battery. (This includes plastic battery boxes and sealed batteries. See ABYC Standard H-2, Ventilation)

Batteries shall be charged by means of an automatically controlled device that is capable of applying the current and voltage appropriate to the type of battery being charged.

The simple answer is YES.
For lead acid batteries it is to capture the electrolyte should it spill out of the batteries.

Here is an article that gives you info on orientation of the batteries. https://marinehowto.com/installation-orientation-of-flooded-batteries-on-boats/
Another thing you need to do to get the most from your batteries.

Additionally you will want to strap the suckers to the boat so if you get flipped they will stay in place. And finally you want to cover the positive terminals so if you drop a wrench it will not start a fire.

That’s the quick and dirty of batteries.

Ours were installed in FRP boxes with bolt on lids. Boxes were secured in steel racks/frames. Really liked how Hunter did that installation.

Oooooh! Another rendezvous in the offing perhaps? Just say when, after June 27th, that is. Colin wanted me to join him in Eagle Harbor today. Sorry, but the kids need to get home. Driving school bus becoming less fun with each passing day, eh?

Our setup is very nice. Nothing squishy about it. Very professional and quality built. Definitely worth a see. Soon. Very soon. Might even get Les turned on.
