Thanks madman
Its incredible that they can make 3-6 ah batteries the same size
Great display of the options! I want to try one of those 6ah batteries.
Keep in mind those 6.0ah batteries use Lithium cells with a lower continuous amperage. Meaning that on a lighty duty tool ( compact drill / impact driver ) you’ll notice the extra amp compared to a 5.0.
But if you put the 6.0 on a heavy duty tool ( grinder / jigsaw / cirk saw etc…. ) you’ll run into the limit of the amperage those cells can provide and it’ll actually perform worse or perhaps only thesame as a 5.0 amp unfortunately 🙂

That’s interesting I always thought bigger battery more power, stupid physics
If using thesame cells then yes that is true. But all lithium cells have a given number of continious amps they can give out. The 3000 milli ampère cells in the 6amp battery back have a lower continious amp rating then the cells used in all 4 and 5 amp battery backs from the top Brands.
The more amps you draw from the cells higher then the rating the more internal resistance in the cells will matter. And thats an incremental thing.
Theres this guy in YouTube who tests all batteries by putting a constant amperage draw on the batteries and timed how long it takes them to drain empty. If you put a big amperage draw ( i believe around 35 to 40 amps ) on the 6 amp battery you only get a marginale increase in runtime compared to the 5 amp.
Thats because the internal resistance in the 3000 milli ampère cells ramps up onder load.
Sorry for crappy english 😀
English is perfect you just lost me with all the facts.lol
