I have a fair bit of construction tools (DeWalt brand) but the batteries are damn expensive
Is it unethical to buy the cheaper compatible batteries

Are the cheaper batteries better than the expensive ones? If not, dewalt is charging you for a superior product, which is fair IMO. Is the difference big enough to justify the difference? That’s up to the customer to decide. If the difference is not worth it, just buy the cheaper one instead.
Is any of this ethical? Probably not. I suspect both manufacturers have poor labor practices and a negative environmental impact. The way I see it, consumers are destroying the planet through indirect means for the most part. Directly, if you’re burning gasoline, and indirectly, when you’re buying stuff from various companies. Those companies are directly destroying the planet buy burning stuff, leaking toxic chemicals into the groundwater etc. If you’re worried about ethics, you might want to look into the environmental impact these two companies have. If you’re serious about this, you might need to do a proper life cycle analysis of the entire production chain, but that’s a topic for another thesis.
You have to keep in mind that power tool batteries are kind of the worst case scenario when it comes to lithium battery safety because they get knocked around, shoved into tool boxes, crushed, etc. of all the consumer products most at risk of fire, tool batteries are up there. That’s part of the reason they are so expensive. At the same time, knock off 18650 cells are generally well known fire hazards on their own.
I think it’s up to you what your risk tolerances are, but if a DeWalt battery burns my house down, at least you have a company to sue. If the Temu battery does the same thing, you are going to be SoL. I’ve been building and repairing various kinds of packs for more than a decade and am quite wary of random bootleg cells. I’ve never had a real Panasonic or Samsung cell fail, only knockoffs.
The cheaper batteries may have a lower true Wh capacity.
But given the cost difference, I’ve found they have a much higher value - I get 80% of the capacity for 30%-50% of the cost.
And you always want to have at least 2 or more batteries to ensure sufficient runtime.
Sounds like a very reasonable compromise.
