The Milwaukee Tool M18 RedLithium XC5.0 offers a Milwaukee-exclusive design that protects against harsh jobsite environments. This protection routes water away from the electronics and out of the battery pack, extends run-time and life by minimizing heat, and prevents pack failures from vibration or drops. This design also allows the battery to operate in extreme cold weather conditions (below O degrees F/-18 degrees C). Managed by Milwaukee’s REDLINK Intelligence, the battery also features overload protection, while the discharge protection prevents cell damage. The XC5.0 will be sold as an accessory to the M18 System, and will have full system compatibility with all M18 cordless solutions.
