I use a number of Makita "36V" tools, like their XCU04Z chainsaw [1]. Like their other yard tools and circular saws and other more power-hungry tools, you clip on two of their 18V LXT battery packs. If you don't need the chainsaw, you can clip one of them on a drill or angle grinder or whatever that only needs 18V. Unfortunately, this endorsement is complicated because they just introduced their "40V" XGT line that's not backwards compatible with the LXT. [2] It's really 36V, just 10 series 21700 cells instead of one, two, or three parallel banks of 5 series 18650 cells. You can get adapters to use your Makita (or red or yellow or orange or green whatever brand you favor) batteries on any other tool brand, but I haven't seen 2xLXT to XGT adapters yet; the form factor is difficult. Perhaps a lanyard with the batteries in a backpack or holster, and a smaller adapter at the tool... Edit: On searching, apparently back in 2020 they filed a patent for a 2x18 to 40V adapter: [3] [4] but I haven't found a released product. The image looks like it could fit nicely in that leaf blower, but it would be absurd on an impact wrench or similar.
