Pretty much all 18V power tool batteries are somewhat the same, it’s 5x lithium cells in series. Aside from the pouch cells, they’re either 5, 10, or 15x 18650s or 21700s and the cells come from only a few reputable brands, so different power tool brands will use the exact same Samsung 18650s in their pack.

I don’t think the communication between tool and battery is a huge deal the way you’re thinking. Some brands’ batteries have overcurrent and undervoltage protection built in, as well as balancing, and other brands’ are pretty much just 5 cells and a temp sensor and the charger and tool have the circuitry for protection and balancing. But afaik, any major brand will let you tap into the + and - contacts and pull 100W from it no problem as long as it’s not too hot.

The special communication they claim on the HP/HO packs to give certain tools more power, I don’t know how much of that is data going back and forth vs those certain tools having a second set of battery contacts. Like pic related, the 6Ah Max Output and 3Ah Octane have an extra + and - pin on either side for more amps, so 6 contacts total, the basic 4.0 on the right doesn’t have those, just the usual +, -, temp, and some 4th data or ID pin. So tools like the angle grinder sense contact with those extra contacts and will run a little harder.

>this is all bullshit
Guarantee you won’t get full power if you actually tested it on most of these brushless high power tools that want the MAX/XR/HP packs. There’s a big difference in power at the top end with the right setup and those adapters def aren’t going to support that.

And it’s definitely worse ergonomics, if you can even use the adapters on certain tools with odd battery placement.

And my third point was the low voltage, also temp management and stuff, and you agreed with that. You can’t disagree with any of those points objectively, the adapters are a compromise in many ways.

Also the new Max Output batteries and the higher demand Brushless tools have the same extra battery contacts as the Octane tools. “Max Output” pack plus “Brushless” tools are the same as the Octane setup but without the Bluetooth app. That new 8.0Ah Max Output pack probably puts out more power than any of the Octane packs.
