Description
Adapts Milwaukee M18 battery packs to Aliexpress power tools that use the Makita battery form factor. No idea if this works on actual Makita tools, but I'd guess not without at least a resistor to fake the thermistor. The slot for the third blade is there if someone wants to take this further, but I never cut in the recess for a terminal because I don't need it. Wire size may need to be upsized, so far the only real-world testing has been to see if it powers the tool.
Made this after showing my neighbor the M18 to Bauer adapter and he asked if I could do one for his Aliexpress impact driver. He bought it after seeing a review on Project Farm a few years ago, not realizing how expensive Makita batteries and chargers were (he's all Milwakuee too), and left it sitting in a drawer until now.
Same M18 battery side and latch models as my M18 to Bauer adapter, same BOM for the screws, heat set inserts and terminals, just a different top. Supports under the overhangs for the sliding rails on the sides, but I didn't find them necessary for the terminal recesses.
