I even have these microballoons:

I haven't used this, but something similar a long time ago.
But I thought I would be able to get the fiberglass down there as I had time to go back and forth many times.
I was thinking it would be better in the end to get the strength of the fiberglass holding it together, but ended up with air

Building battery:

It seems I don't have many decent photos, so it seems this will be it for now.
450A fuse might be on the low side, but I have a few of these..
It should be able to take bursts of a lot more it seems:

The voltages were all over the place:

They never were perfectly equal, so it might not be too bad.
I balanced them for a long time, (like 48hours or something) now it looks like this:

Time will tell

Hard to see in the picture, but it is very tight to fit the wiring over the cells:

It would probably be possible to get some more room if I built a new top part now when I can see exactly how much room I have over it.

It isn't sealed yet, but still a milestone to have a "finished" battery in place

Designing some peaces here and there:

Bracket for radiator wings and battery cover.

Should slide in here.

I had this skid plate I planned to use with some small modifications.
Well, not much left of it.

This is how the right side will look.

And the left side will look something like this.

I will probably bolt this chain guard to the skidplate instead of the motor.

I haven't updated this for a long time..
Mostly because nothing have happened

I have got some alu to start welding as soon as I find some time for it at least.
