Festool/DeWalt battery adaptors?

[DashZero]

Because we are conditioned to think that “saving money” is better than saving time.  If you can buy the tool and pay for it with the job and have money left over, it doesn’t matter.  You didn’t buy it,  the job bought it for you. 

Obviously all down to opinions etc but, personally I wouldn’t use batteries on a cross platform, unless the batteries and/or adapters, were designed and backed up by the relevant manufacturers.
The majority of my power tools are top end from their respective brand, and they are used in a professional capacity, so not worth the risk to me. We buy our batteries in bulk, from 4 to 12 at a time, and get the relevant discount.
I understand that for some, cost is a factor but, where is the sense in buying tools that cost hundreds or thousands of pounds/dollars and euros, only to scrimp on batteries?

I think of batteries in the same context as the tools themselves, one is of no use without the other.
Best practice is, get a quote and gulp, sigh or even swear quietly, then buy them. Same goes for chargers, drill bits, sanding pads, blades, biscuits, Dominos, screws, nails and glue. It’s part of the big picture.
In my case, it helps keep the tax bills lower but, even for a part timer or hobbyist, this stuff is needed if the tools are being used properly.

I am looking for a certain adaptor, that turns £10 notes into £50 notes!  [tongue]

If the job bought the tools, then it needs to buy the batteries too.

A battery adaptor reminds me of rims and tires sticking out from the side of a car with an adaptor hub. A waste time to save money.  And time is more valuable.

....Where lawyers and insurance companies won't go.

Power to the person for going for this, I'm sure many will be tempted.  But I don't think I would be wanting to explain to my insurance agent while standing next to my smoldering garage that I was using a Russian made, ebay sold, battery pack adapter.

Note: this is nothing against russia, they make great spacecraft/etc.  They just aren't a point of origin for much of anything folks buy.

Isn't there more going on than just transfer of power between the battery and the tool?

Does the tool monitor battery discharge rate, voltage drop, and temp?

If you were able to cross-connect a battery from Brand A with a Brand B tool that
communication/safety feature is lost, and maybe even creating a potentially dangerous
situation or at the least damaging the battery and/or the tool.

Yes,  you can see me mentioning that in my older post.

Almost anyone today with 3D printers and such, can make a plastic bracket, and come up with eclectically connections to physically connect  2 different brands, that is the easy part.  It's everything else, most of which will be unknown to anyone outside the manufacture.

The other aspects are what causes the danger with this and why no company will make these. If it could be done safely, you would see normal adapter type companies making these.  The legal liability is just to big.

Everyone sees the "need" and desire for such a thing.  If someone has a massive amount of say Milkwaulkee tools, but there is one tool made by someone else they need/want, they really don't want to have one random battery.  It's the general issue with Festool, some tools like the HKC make a lot of sense in battery form.  But how often would I use it?  It might sit for very long times between use, not good for a battery tool. If I could get it bare tool and use my M18 batteries, then a whole different story.  But I'm not going to take that risk.
