I had thought it wouldn't happen nearly as quickly as this, power tool companies embracing larger than 18650 cells in their battery packs. I figured they would stick with 18650 cells for the size/shape/weight etc.
I saw a new 12Ah milwaukee tool battery at Home Depot last night and it looked odd.... it was larger in footprint than their normal batteries and I put one side by side and if was larger all around so I figured they were probably using 20700 or 21700 cells in it. After checking online there are sites touting 21700 cells.
This may be starting a new Ah war with the power tool manufacturers with them possibly offering 2 lines of batteries, normal to heavy output 18650 based and super output 21700 cells. I will say that 12A pack was massive and heavy I wouldn't want to have to hold it in the air all day rather have smaller batteries and swap them more often for the weight.
Will there be phone power banks using these cells soon in the stores soon? I was thinking bluetooth speakers but some of them are using non standard packs in them instead.
Makes me want to consider making sure any future chargers I buy supports longer cells as I think we will even see rechargeable flashlights in stores (built in 21700) in the future within perhaps 5 years from now.
Dewalt has a 9A battery pack out but the 12A Milwaukee IMO is going to probably push Dewalt into incorporating 21700 technology to "match" capacity without going to a 4 layer pack.
