You should be able to deduct a percentage of your house (shop) and the scissor lift. You have to calculate the percentage of use and the square footage of the shop. This is why I would also claim one of your bedrooms as a dedicated office for the business.

All the tools and other hardware/materials you buy are deductible, too (including any equipment you buy to destroy or your solar trailer).

May or may not want to allocate house to business use, as there is special tax treatment for sale of principal residence. Have to predict the future to know what is best.
HOA fees are something that can only be deducted if business use. For a property where fees are high, turning the property into a rental lets them be deductible, along with all the other expenses. All while taking standard deduction instead of itemizing. So where neighboring properties are identical, if you and your neighbor both become landlords (and tenants) to each other, may be advantageous.
Oh right, I did that. It isn't a very large deduction unfortunately. I deduct everything. But I owe 278K for last year, so all of these deductions are peanuts in comparison. And any extra money I make goes into investments. I am pulling money from investments just to pay last years tax bills. Hopefully this will get my family out of poverty for a few generations if I use this money effectively.
I have a great tax guy and deduct every little thing that goes through my business account, but it doesn't even scratch how much I owe.
I traded my cash for crypto. I only have $200 in cash right now besides tax bill and investments lol. I am actually studying investment strategies and also have a well known financial advisor. I think I have everything setup as best as I can. I am still quite ignorant on the topic though, but I am studying as much as possible.
Indeed, very true. And no, I am doing higher risk crypto holdings now that I have substantial equity and other investments. I am being careful but I do not mind the volatility. My ex girlfriend is a day trader and I am extremely conservative, investment wise, compared to her haha. I will be ok. I don't sell unless I profit.
Sorry everyone for the tangent. Oops.
Here is a big battery update. I packed up the box with the cells and used deck screws to seal it. Followed the hazmat protocol included. Used harsh chemical resistant gloves and a mask etc:

Might be worth keeping an eye on this thread. More reports of leaking cells ... not BB.

That would make sense, it's not like Big Battery is going to order the extra-leaky cells. Their design might benefit from a few tweaks (what design doesn't?) but I think it's more likely a battery supplier problem. I would worry more about any particular battery company being around to service your XX year warranty. Not being critical of BB, lots of businesses go under eventually. For instance I have a lifetime warranty on my car paint job.. the old owner was in business 30 years, sold the business, and the new guy went under a year later.Might be worth keeping an eye on this thread.

In our favor, an easily serviceable design like BB uses would make it easy to drop in new cells with the latest technology and capacity, even if they can't or won't service your dead battery.

First Rule of Business: Accept No Liability
Quote from the following article on quality testing Lithium batteries.
"Depending on cell type, five percent or more of the lithium-ion cells currently produced for the auto industry may have undetected leaks."
www.qualitymag.com
It sounds like INFICON has developed a non-destructive testing process to capture quality issues on prismatic, cylindrical and pouch cells. They published a SAE technical paper on the process. https://www.sae.org/publications/technical-papers/content/2020-01-0448/
@MrGreen might want to have his team review and see if they could benefit from the process.
Another article with some more details on the process.

Setting a new standard for battery leak testing - Charged EVs
Defective cells can shorten battery life, decrease range, and lead to safety issues. A leaky cell housing, one common failure mode for Li-ion batteries, can allow ambient humidity to come in contact with the electrolyte, triggering an exothermic (heat-releasing) chemical reaction. Currently...

Or they can just warranty the battery if a cell leaks I suppose.
I'm starting to think the ABS plastic case is the way to go. Especially if you have a mobile or "creative" mounting situation. The metal cases are probably more susceptible to leaking out the hazardous electrolyte. SOK has a plastic case coming next month, Battleborne, Lion Energy, Renogy, AmpereTime, etc are all ABS or some form of plastic.
With the sealed cases you would never know it was leaking. I wonder if Battleborn or Lion Energy warranty returns have had any leaking cells?
Battle Born does not use prismatic cells.

At this point we do not know where the leak is coming from, I.E. from the safety vent? from damaged body of the cell?, BB has some batteries (about 10 of them?) that leak in their warehouse, they also receive the bad pack from Seth. I would think by now BB can do the failure analyzis on its own 10 batteries that leaked and tell us what they find.
More than likely, it is coming from the over pressure relief valve.
The evidence we currently have is that Big battery themselves found 11 leaky cells in their inventory, I had a leaky cell, and Seth possibly had a leaky cell. That is 13 cells in a single batch, and all were lishen cells.
I think it might be the supplier at this point. Bigbattery has a lot of people working their quality control, and they use good equipment. So I am starting to think it was the cell supplier.
Because bigbattery also has their own issue of leaking cells, I am guessing that we cannot blame their shipping company. These cells are leaking before they leave bigbattery.
At this point, I am thinking the problem is Lishen cells. What do you guys think?
