This bundle pairs the Milwaukee 48-59-1862S M18 REDLITHIUM HIGH OUTPUT XC 6.0Ah Battery 2-Pack Starter Kit with the Milwaukee 2688-20 M18 Compact Heat Gun, giving you two high-output packs, a charger, and a cordless heat gun in one order. Model Numbers: 48-59-1862S ((2) HIGH OUTPUT XC6.0 batteries + charger), 2688-20 (M18 Compact Heat Gun, tool only).

The 48-59-1862S kit includes two M18 REDLITHIUM HIGH OUTPUT XC6.0 battery packs and one M18 charger. Milwaukee rates these packs at 50% more power and 50% cooler running than standard M18 REDLITHIUM XC packs, with fade-free power under heavy applications and increased power in extreme cold (below 0°F / -18°C). REDLINK Intelligence provides overload protection through communication between tool, battery, and charger, and each pack has an onboard fuel gauge. The batteries work with 150+ M18 solutions.

The 2688-20 is a cordless heat gun built for heat shrink tubing, wire terminals, softening adhesives, and plastic forming. It reaches operational temperature in 7 seconds, tops out at 875°F, and moves 6 CFM of air. At 6.39 in long and 1.7 lbs, it fits where a full-size heat gun won't. A guarded nozzle helps protect nearby surfaces, an integrated ladder hook gives you somewhere to hang it between tasks, and an LED light helps in dark work areas. REDLINK intelligence manages temperature and protects against overload, overheating, and over-discharge.

This is a strong pick for electricians, automotive techs, HVAC and maintenance crews, and low-voltage installers who want to add high-output M18 packs and a charger while picking up a compact cordless heat gun.

Stock Up on HIGH OUTPUT Packs and Get Cordless Heat

Two of Milwaukee's high-output packs and a charger, plus a compact heat gun that uses them.

• Who it's for: Electricians, automotive techs, HVAC and maintenance crews who want more M18 packs and a fast, compact heat gun for connection and repair work.
• Why it stands out: HIGH OUTPUT XC6.0 packs with 50% more power than standard XC, plus a heat gun that's up to temperature in 7 seconds and fits into tight spaces.
• Worth knowing: Milwaukee's "over 40 connections" runtime claim for the 2688-20 is rated on an XC5.0 battery, not the HIGH OUTPUT XC6.0 packs included here, so actual results will differ. The heat gun is built for targeted heating, not long broad-surface sessions.
