Its design emphasizes resilience and real world efficiency, helping you stay productive from first light to the last task. The included fuel gauge keeps you informed about remaining run time, so you can plan recharges with confidence and minimize downtime.

Power and durability for tough days

On the job site you need power that follows you through long tasks, not a quick drop off. The XC 5.0 pack is engineered to deliver sustained performance, with protection that helps it endure harsh conditions. Water is routed away from the electronics, heat is managed to extend run time, and the pack is designed to resist the effects of vibration and accidental drops. In addition, the battery is engineered to operate in extreme cold conditions, allowing you to work in cooler environments without compromising performance.

• All weather performance with fade free power in challenging environments
• Rugged construction designed to withstand site abuse and rough handling
• REDLINK Intelligence provides overload protection to safeguard tools and batteries
• Discharge protection helps prevent cell damage during demanding tasks

System versatility and practical use

One of the strengths of this starter kit is its broad compatibility with the M18 system. It plays nicely with 60 plus M18 cordless solutions, so you can mix and match tools without buying separate battery packs for each unit. The included option to add any M18 Tool Only accessory lets you tailor a kit to your workflow, supporting a wider range of applications without starting from scratch. This flexibility is especially useful for crews or DIYers who rely on multiple tools across different job sites.

• Wide compatibility with 60 or more M18 cordless tools
• Easy to build a personalized kit by adding tool options as needed
• Durable, long run time that sustains productivity between charges
