A Milwaukee M18 starter bundle built around two REDLITHIUM XC5.0 5.0Ah battery packs and a multi-voltage M18/M12 charger, with an M18 oscillating multi-tool bare tool included. The XC5.0 packs use REDLINK electronics for overload protection and an onboard FUEL gauge that shows remaining charge. The batteries fit more than 200 M18 tools, so the kit works as a platform entry point or as spare runtime for someone already on M18. It suits buyers who want two high-capacity packs and a cordless multi-tool in one go; the trade-off is that the multi-tool arrives bare, with no blades or accessories, and the kit carries no drill or driver.

Rated 4.9 out of 5 across 180 ratings, the kit is well received by M18 owners. Buyers value the runtime of the XC5.0 packs and the convenience of the dual-voltage charger.
The Milwaukee M18 REDLITHIUM XC5.0 Starter Kit (48-59-1852B) combines two extended capacity 18V batteries, a multi-voltage charger and an M18 oscillating multi-tool (bare tool). It is a base for building out an M18 cordless tool set.
The batteries deliver up to 2.5X more runtime, 20% more power and 2X more recharges than standard lithium-ion batteries. REDLINK intelligence uses communication between the tool, battery and charger to optimize performance and protect against overload. A fuel gauge on the battery shows remaining runtime.
The batteries are built for all-weather performance and provide fade-free power in extreme jobsite conditions. They power more than 200 Milwaukee M18 cordless power tools, and any M18 tool-only option can be added to build your own kit.
