Battery box floor is laminated 1/8” aluminum plate!


Recommended Posts

I had no idea, I am highly impressed. I was starting to install a computer fan below the floor for moderating temperature fluctuations.

I was really shocked when I hit metal.... 😳

My one hour job turned into four. I was using a 4” hole saw and 3/4 of the way through my Dewalt drill gears blew up. I finished with an electric scroll saw and a hacksaw blade in a straight handle. Then I went full analog and got out  my 20,000 rpm air die grinder. Ugly..... fortunately it will all be hidden.

I want to keep moisture away from the laminations, so I wil seal all that with epoxy before mounting the fan with an aluminum plate. Which I also made today....

WOW!!!  That's good to know.  Did you also vent the sides of the battery box?  Wondering if the entire box is reinforced with the laminated aluminum?  Thanks for sharing - this will help those of us lagging behind on this project.  🙂

I really doubt that any parts other than the weight supporting floor are so very robust. I have already drilled some holes in the sides, which are 1/8” blown chopped fiber fiberglass (not honeycomb or hand laid) and they super easy to drill with a bi-metal hole saw. I haven’t drilled the top but I don’t know why they would put metal there. All the load is in the bottom, going straight down to the trailer frame, via the central support. I will find out about the top because I will drill air holes there soon...

You could easily put a fan in the aft side wall, close to the bottom, centered. There is around 3” of space between it and the bed wall, and nothing in the way. It will cool or warm the batteries just as well. I wanted a central floor location so it would also be effective at cooling the front electronics bay (with an added air vent there). A rear located fan will still do that, but maybe not quite as much. Here is a view looking up at my new top rear air vent. The pantry is on the right top. The battery box is on the right bottom.

The top of the battery box is separated from the bottom of the pantry by about 4” of space all the way across! Again, I had no idea! Why such a huge gap? I would rather have the secret compartment be much deeper to take advantage of that big hidden volume.

This has been a big learning experience for me. I will be posting threads when I get everything done.
