Mounting a battery box ???

[Techno]

Getting ready to build my battery box but the problem is how to mount this thing? I don't have a floor to mount to just the hull.
The box is just a picture frame of cast aluminum surrounding 2 925 odyssey batteries. 3 lugs for the top hold down screws.
Any other stuff needed to hold it in place.

3 solutions but none seem that great.

• Bond the box to the hull with some super adhesive stuff.
• Bolt the box to a plywood panel that is bonded to the hull. Still can't remove it though. bolts would be from underneath.
• Bolt it to 2 stringer like mounts that are bonded in on either side of it. Horizontal bolts VS the vertical of the plywood deal.

Any ideas?

i'm kinda in the same situation,got my eddie marine battery box,came with the spacer and trick bolts but none for the floor mounting.
now the fun part is where to get the same bolts(tapered with allen sets)and to get a nut under a glassed floor

glass in some wood and bolt it down!

How bout a simple key hole using a router on the stringers?

Why not glass a piece to the transom and mount your battery on that? Kinda like a shelf. Weight also gets moved as far back as possible this way.

I bought a billet holder for my Odyssey battery. I needed a way to get underneath the front so I could easily slide the battery out. I sunk threaded inserts into the floor and bolted it down using standoffs to raise the box just enough to get an allen wrench under it in the front.

Have a look at item nr. 97802A317 in the McMaster-Carr catalog. I've used 'um for bolting down seats where ya can't get to the underside of the floor to install a nut. Bunch better then wood screws.

I put threaded inserts in plywood with epoxy and bolted my mount to it. The pullout is more than you'll ever need.

I just did mine, so tell me what you think.....

First drilled holes. The big hole is to get the SS T nuts under the floor.... I painted gel with a brush to seal the wood back off....

[Forkin' Crazy]

I pulled the T nuts into the holes with a zip tie and then snugged them with a bolt to sink the prongs on the T nut into the floor....

Bolted the bottom of the box down with SS countersunk socket head bolts...

Finish.....

Techno do you really want your battery on the floor? Seems like you want it a little more elevated considering your occasional forgetfulness

Funny guy That problem is solved. Idiot proof check valves swing down to seal the holes if the drain plugs aren't in. They will be idiot proved soon.

The drilling holes in the floor ain't a good idea. Since I don't have a floor all those fittings will be dragging through the water.
Thought of the inserts but to be honest kind of lazy. Gotta order them you know.

I think I'll combine the board and stringer idea and install a false floor. Off the hull and can get to the bottom. Easy to remove it if I decide on a different location.
A board on 2 little stringer like things. Build it, coat it, then bond it in. AND its off the floor.


BTW these batteries are almost square with a metal jacket. 25lbs a peice. The terminals have a torque slipping deal on it so you always tighten to proper torque without a torque wrench.
