Has anyone used this
TAB Dual Battery Conversion Kit for their front tub? I won't be using that because it's moot since the bottom of the tray is made to fit the original tub and I'm upgrading to the Sea Biscuit center tub, so here are my questions.

1. Do I need to enclose the new batteries in a covered box inside the new SB tub which is very similar to the aluminum nuCamp tubs or can I use
trays like these instead?
2. Or do I need to find a dual battery box to fit inside the new tub? I'm having difficulty since most of the boxes are just too large for two group 24 batteries.
Here are some boxes I've found and they all seem too large, except
this one MIGHT fit but it will be very close and will take up alot of the space in my new tub.
Here's a pic of the new tub. I will be adding a second identical battery to what you see in the pic and an inverter. TIA
BTW, IF it's crucial to get an enclosed battery box, I've also been looking at totes that might fit or a hard sided plastic toolbox which some people on YT have done.
And my other question would be... if anyone knows of a battery box that would fit in that section with two group 24 batteries even turned on their side.
And... to add to this again...
I think I found the Holy Grail of battery boxes that looks like it will work! When I searched for it, a previous post (
by Verna on this thread) showed up but with a faulty link for this product.
Here it is... 
It's a battery box for two golf cart batteries but it's just the right size to fit in my tub!
