The Milwaukee M18 RedLithium High Output XC6.0 is a 6.0Ah lithium-ion pack for Milwaukee's M18 cordless system. Milwaukee rates it for 50% more power and 50% cooler running than the standard RedLithium XC packs, and it holds up in cold below 0°F. It fits more than 250 M18 tools, so it is the pack to reach for when a high-draw tool like a circular saw or grinder needs more muscle. Against Milwaukee's compact CP packs it trades weight for runtime and output; against the bigger 12.0Ah High Output pack it is lighter and easier to handle. Owners rate it highly for runtime and durability.
