The Milwaukee M18 REDLITHIUM Full-Day Power Bundle pairs one XC 5.0Ah battery (48-11-1850), two HIGH OUTPUT XC6.0 battery packs, and a compatible M18 charger into a single complete power kit for Milwaukee M18 cordless tools. This bundle is designed for M18 users who run multiple tools throughout the day and need a mixed-capacity power setup that matches the right battery to the right application — from everyday drilling and driving to heavy-demand corded-replacement work.

The XC 5.0Ah (48-11-1850) is Milwaukee's dependable extended-capacity workhorse. Compared to standard 18V lithium-ion packs, it delivers up to 2.5× more runtime, 20% more power, and 2× longer life. It is the right battery for everyday M18 use — drills, impact drivers, lights, multi-tools, and service work where you want solid runtime without the bulk of a larger pack. The pack construction is designed to handle vibration and drops, and a water protection barrier routes moisture away from electronics. Cold-weather operation is rated below 0°F / -18°C.

The two HIGH OUTPUT XC6.0 packs step things up significantly for demanding work. Milwaukee rates them at 50% more power and 50% cooler operation compared to standard M18 XC batteries — which matters when you are running a recip saw through structural material, driving a rotary hammer through concrete, or pushing a circular saw through engineered lumber all day. Fade-free power delivery and strong cold-weather performance below 0°F / -18°C keep these packs performing when conditions get tougher. With 150+ compatible M18 solutions, they work across Milwaukee's broadest cordless tool range.

Having three batteries with a charger in this bundle makes sense for real-world workflows. Two packs in the HIGH OUTPUT tier means one can be in the tool while the other charges, keeping your hardest-working tool running without a break. The XC 5.0 handles lighter tools independently, so you are never pulling a premium pack off the charger just to run a drill or a flashlight. All three batteries share REDLINK Intelligence protection, onboard fuel gauges, and full M18 platform compatibility.

This bundle is the right fit for electricians, plumbers, carpenters, HVAC techs, general contractors, and serious remodelers who run multiple M18 tools throughout the day and want a full-day power setup without piecing together batteries and a charger separately.
