MAXIMIZE RUNTIME, MINIMIZE WEIGHT – Industrial 18V Lithium-Ion Starter Pack with Advanced 21700 Cell Architecture

Eliminate jobsite power dropouts and bulky tool configurations with the Bosch GXS18V-11N25 CORE18V® Starter Kit. Explicitly engineered for professional concrete contractors, MEP installation technicians, finish carpenters, and structural steel fabricators, this premium power package pairs two ultra-efficient CORE18V® 4.0 Ah compact batteries with a high-amperage rapid-charging station. Utilizing advanced single-layer 21700 lithium-ion cell technology, these next-generation fuel cells yield 60% more raw power and double the runtime of older, standard 2.0 Ah battery cells while maintaining an incredibly lightweight footprint. This industrial power pack is perfect for reducing arm fatigue during continuous overhead masonry drilling, structural metal grinding, heavy timber cutting, and light-duty concrete chipping applications, giving your cordless tools maximum punch without weighing down your tool belt.

Every element of this high-conversion starter system is fine-tuned for ultimate mechanical efficiency and prolonged service life. The included batteries are wrapped in Bosch-exclusive CoolPack™ 2.0 thermal dissipation housings, which pull destructive heat away from internal components to speed up cooling times and extend overall battery lifetime. Inside the protective shells, low-resistance copper end plates and robust power rails ensure a highly stable current flow under peak mechanical stress. When your cells drain out, the bundled GAL18V-40 4-amp rapid charger goes to work, pouring double the charging current into the pack compared to entry-level standard chargers to achieve a full 100% capacity replenishment in just 65 minutes. Featuring a built-in battery status indicator and smart regulated dual-mode electronics, the station rapidly pumps the cell to 80% capacity before shifting to a protective long-life mode for the final 20%. Fully integrated into the multi-brand AMPShare™ ecosystem, this battery kit bridges seamless tool compatibility across a vast, growing platform of commercial cordless gear.

Key Features

• Advanced 21700 Cell Technology: Single-layer cell matrix delivers massive power output and maximum efficiency for standard to medium-duty tool tasks.
• 60% Power Multiplication: High-density cell profile provides double the overall running capacity and an aggressive 60% increase in power over entry-level BAT612 batteries.
• Exclusive CoolPack 2.0 Insulation: High-tech thermal management case cools internal components quickly to guard against heat degradation and dramatically improve long-term cycle life.
• Heavy-Duty Low-Resistance Internals: Forged with specialized copper end plates, premium power rails, and flexible circuitry to reduce electrical resistance.
• 4-Amp Rapid Charging Station: High-amperage output supplies 2X the charging current of older GAL18V-20 chargers, ensuring less down-time on the jobsite.
• Smart Regulated Dual-Mode Profile: Maximizes long-term battery health by fast-charging the cell up to 80%, then safely tapering the final 20% into long-life mode.
• Universal AMPShare System Platform: Multi-brand system architecture offers cross-brand compatibility across all Bosch 18V cordless tools and partnered AMPShare alliance lines.

💡 PRO-TIP: To maximize the lifespan of your CORE18V lithium-ion batteries, avoid leaving them sitting completely drained on your truck bed in freezing or blistering weather. If a battery shuts down from heavy discharge while drilling or grinding, let it rest for 5 minutes to stabilize its internal temperature before sliding it into the 4-amp charger. This allows the CoolPack 2.0 system to calibrate, initiating fast-charge mode instantly without triggering an over-temperature delay cycle!
