For those familiar with the Softail frame. Circa 1999.
The main breakers/fuses are located in a box attached towards the front of the lower rear fender.

For T~S I am going to a swingarm mounted fender.

I do not want the components, connections, harnesses subjected to the movement and beating they could now take no longer being protected by the suspension.

A partial solution is to shorten the harnesses, go to a smaller breaker box and relocate it to inside the oil tank battery tray.

Here is where the problem comes in.
Standard 12v cycle batteries take up all but a very small of area in the tray. Meaning no room for even the smallest breaker boxes I was able to find.

Thought I had found a solution using a lithium ion battery.
But concern has been expressed to me about going that route. Guess there have been cases of them "exploding".
Though have heard similar about lad/acid if the charging system goes on the fritz.

I can use a battery of standard height and depth.
Length is the problem.
The lithium ions I have found are roughly half the length. Which gives me the room for a box.
Anyone aware of other types/size batteries that may work for my application?

It's a motorcycle. Everything about it has a risk factor above "normal." Besides, it they all exploded, they couldn't sell them.

The Lithium batteries for motorcycle and car use, are Lithium iron phospate, not really subject to burning or exploding.

True.

That is what I needed to hear. :) Thanks Bobf.
They are not cheap. But seem to be my best solution.
Nice to know I can move on to the next hic-up in T~S`s build and put this one to rest.

This is my first Softail so learning the differences as I go.

I have two different brands. One from Stark and one from Bike Master. Both seem to work nicely. The small 12ah will crank my Sportster just fine, and is about 1/2 the size of the "normal" battery. This one is not the recommended battery for a Sportster, but tried it anyway before putting it in the Lifan LF-250, where it lives. Only about 2/3 the size of the stock battery for that bike as well.
