Is this the product?
https://amtechdiy.com/product/3-6v-cordless-lithium-screwdriver-kit/
I see in the pictures it states using a 6V wall wart charger. Can you confirm that this is what was included?

Almost ALL of the cordless drills are made in China, and almost ALL lithium batteries. The west needs to start making things again, and put China out of business.

I agree, but we just can't compete with cheaper labor costs.

The above posts are amazing to me, when you consider that many of us will "pay extra" for quality tool (pick any of the higher-end brand names). If that is the case, then why not buy an in-country made item, and pay something more for it, vs the cheaper version of it? I would ...
I've always advocated that basic components be built anywhere, but the design, final assembly (and documentation!) gets done in the country of consumption.
I think manufacturing will come back to this country, but the political willpower that allowed it to move overseas needs to shift back in this direction.
I'm tracking Midnite Solar versions of inverters ... possibly they might replace my Magnum inverter, if and when it ever dies ... I hope Midnite's stuff mostly resembles made in america ...

Doing more research, mosty harmless
I am confused - is the one you disassembled with the ni-cads in it old? And the caught fire one Li-ion? I think I missed this along the way.
Got pictures of the fried one? or is there anything other than a pile of ash and wire left?
Are you going to contact Am-Tech and see if they want it back or to pony up for the damage?

The thing is many people wouldn't necessarily know the difference between a native company and a native manufacturer, take the above company amtech the only thing they produce is packaging everything is sourced from cheaper countries then has their clamshell added, but as a uninformed buyer you would think it's British. Then you have brands that claim to be from countries when they aren't like MG here is covered in marketing stating it's British when in reality it's saic a Chinese company.

Many people might not know, but high-end users (of, for example, tools) would know, as they do the research ...
Hopefully, companies will recognize this, and bring some form of manufacturing back into this country. It takes money, and perhaps the money is there for "the high end" of any given product line, with multiple variations available.

I’ve been half-@ssedly assembling all my lithium ion batteries in one place. Lots of Ryobi and Milwaukee packs. And a pile of 18650’s. Forgot about the old phones.
Not sure if I need to worry about the eneloops. Quick google doesn’t pull up any fire references.
Need to put them all in a metal box somewhere. Though I’d like to keep them in air conditioned space.
Maybe a steel job box.
Saw a good recommendation about housing chargers in a metal mailbox. Steel for fire protection but light enough to dissipate any pressure.

This image says "amtech" The image provided by the OP has "Am-Tech". ...
I mentioned earlier steel won't prevent squat with lithium batteries if your worried stainless is the way to go
I mentioned earlier amtech and am-tech are one in the same

The Midnite Rosie inverter/charger, Hawkes bay and Barcelona and their classic SCCs are built in Arlington, WA. The exception is their "one" AIO from China.

Wow this thread is another reminder to be careful.
Today I was helping a relative setup one of the cheapest Weedwhacker's I have ever seen. The LI-ion battery pack did not even have an led light for charge status.
I said to her when I was leaving that she should not leave the battery unattended while charging. After reading this I am going to have to call her in the morning and tell her not to leave the battery in the house but in the tool shed.
I forgot about these things just suddenly going off while in storage.

Thought I should mention after discussing it in another thread, turns out even stainless steel will melt during a lithium-ion fire some form of ceramic would likely be the most cost effective form of safety, even an air tight enclosure doesn't really help as li-ion produces it own oxygen during a fire hence why it's able to reach such high temperatures.
As @Luk88 pointed out fires like this aren't localized to cheap Chinese cells (though QC is definitely more refined in better brands) any cell can have a faulty separator which can cause a fire.

And can you confirm the charger that was used to initially charge the screwdriver was the included 6V? Maybe confirm this with a multi-meter?
Its likely bull that it was 6v it couldn't be, either a single li-ion is 3.7v nominal or two in series is 7.4v.
It's the other end of the spectrum here but check out the outlandish advertised voltage of this fake Makita drill here in Thailand 259v 50ah

BTW I did have a Dyson cordless stick vac cleaner (till the battery lost capacity - I later found this was a Dyson scam as the bms inside did not include any form of balancing so quite quickly the 8S pack got out of limits and shut down - I ketp they cells and found it a simple matter to rebalance the cells and they still have vg SOH but Im afraid to use lion cells). Dyson went on the skip along with its overhyped reputation (now use a Shark which is 1/3rd price and 10x better).
However OTP https://globalnews.ca/news/10252713/battery-for-dyson-fire-risk/ The battery pack is run at max current for up to 30 mins - thats really caning a lion battery in a way only RC nerds understand

Yes it was the included charger and it measured 5.4V

Not lion, just buying some more of these, really great strong 12v lights, I have them in my place, albeit in metal & plaster housing, just noticed this in the customer reviews. just takes a small production fault I guess. He did get a refund

But they will melt steel boxes? And a house is ultimately flamable.

You have to take the precautions you are comfortable with. Don't give it extra fuel by leaving it in a pile of flammable junk. To be really safe would have to keep them in a detached structure when not in use. Outdoor shed would be ideal. Just like some are building detached powerhouses or power trailers.
