Keep your entire jobsite humming and eliminate commercial productivity bottlenecks with the bulk Milwaukee® M18™ REDLITHIUM™ XC5.0 10-Pack. Specifically designed for large-scale electrical, plumbing, mechanical, and general contracting fleets, this fleet-sized package outfits your crew with ten premium 18-volt extended capacity power cells. Each battery pack utilizes advanced lithium-ion chemistry to deliver up to 2.5X more runtime and 20% more raw power than standard previous-generation lithium cells. This translates directly to accelerated application speeds, higher sustained torque under heavy loads, and a significantly broadened application range for demanding trade tools like deep-cutting band saws, high-torque impact wrenches, and heavy rotary hammers. Every pack in this industrial 10-pack is reinforced with a best-in-class structural enclosure featuring proprietary shock-absorbing rubber overmolds and internal cell separators to insulate against violent drops, vibration, and typical jobsite abuse. Integrated internal water routing paths deflect damaging moisture away from sensitive electronics, while advanced REDLINK™ Intelligence manages digital communication between the tool, pack, and charger to guard against destructive overloads and thermal spikes. Built to perform consistently in punishing field environments, these fade-free batteries deliver constant, uniform power in extreme weather ranging from sub-zero winter depths to scorching summer heatwaves, complete with an onboard 4-LED fuel gauge that clearly displays real-time remaining capacity.
