Why just plug up these nasty holes in your garage
You are not using it for a car anyway, so why the forced ventilation?
An even better idea would be to utilize one of the holes to install a minisplit air conditioner and heat up that garage to comfy levels, slap some Styrofoam to the walls and have a heated workspace
Also, if you are willing to do so, cover your roof in at least 20 more solar panels and operate that minisplit for free
I beliefe you were pretty much upset from putting up even these two panels but pro tip: Get some of these suction cup lifter handle thingies. With these you can easily hold on to the panel with one hand over your back while climbing the ladder with the other hand.

Thera are two SEVERE issues with this design. Its a axtreme fire hazard! Timber and plywood are flammable materials and should never used near any batteries, especially when left unattended for extended time. Another issue is that charging lead acid batteries should be performed only in ventilated areas, so getting it enclosed and not ventilated is not recommended and might be dangerous. I see you use LiFePO4 batteries, but thermal runaway could still be an issue for those. I wouldn't keep it that way, but you do you.

First of all, your temperature sensor position is maybe not so useful. Take a look at Zerobrains discussion with a lithium battery expert, who explains where the sensor should be installed. Secondly, many BMS have a protection against charging at too low temperatures (did you test your BMS) which you perhaps could use to start charging at the well measured right temperature and which can as well switch off your heating. And as a last point, you can very effectively warm the batteries up by discharging them.

I was really hoping to see you testing the box for yourself. :D
Would you have any personal interest in making a heated chamber (or area) for a human? I. e. for working at a workshop workbench for a long time in low temperatures. Or a sauna box even? :) The later would have to be DC and screened (if electrically heated) to reduce the AC EMF at close proximity.

Other people have mentioned what a bad idea it is to have a flammable box, but I've got to say having no redundancy in the temperature control loop is pretty bad too you should at least have a thermal fuse somewhere that will blow if the temperatures get too hot, otherwise you're just asking for trouble.

Wouldnt it be better to just heat the batteries during the Day?
There wont be any charging at night. You could save some Power this way,
Also how hot Do the batteries get during a heavy load?
Maybe you should add over temperature protection to be save.

Nice box! I'm fairly confident that the heat generated from normal use will maintain a Cosy temperature. You may, in the summer, even have to add fresh air ventilation to keep them cool!
Would love to see a long term follow-up video!

You could've used an old/broken fridge instead of that box and also save yourself the trouble of building it. In addition, the refrigerator is more robust, has more space and looks better.

Phrases I learned today:
Wood lathe for 2x4 or board
Mineral wool for that type of insulation.
I'm fascinating, and for both I had to turn on subtitles to understand.

greatscottlab The gasket around the door seems like the easiest way for heat to escape, it would be interesting to see a thermal video of the box when it's really cold in the garage.

Surely you don't need to worry about inefficiency as long as all the components are inside the chamber because the inefficiency just comes out as heat?

It seems those carbon film heat pads are not made for 110/120v AC? Oh well, I'm heating my doggies water bowl so the silicon pads will do for now.

Lovely engineering! You should compare this box to the food delivery boxes with reflective insulation to test which is better.

They do make a ventilation system that exchanges the warm air inside with the cold air outside to minimize heat loss in the room.

I used heated seed germination mats. They come with everything built in to maintain a 90 f temp. No other electronics needed.
