Milwaukee M18 REDLITHIUM XC5.0 Extended Capacity Battery Pack

Got a brand new Milwaukee M18 XC5.0 battery here. It's still in the original packaging, never been used. These are great for getting way more runtime than the standard packs, says 66% more than the 3.0 ones on the box. If you run M18 tools you know these are the ones to have. Just an extra I dont need right now.
