Powerful performance for on-the-go tasks

Meet the AstroAI Upgraded 4000mAh 20V MAX battery, a compact power unit designed to extend your runtime on DIY projects, camping trips, and quick home repairs. The 4Ah capacity translates to longer use between charges, helping you stay productive without frequent recharging. Real-world sessions may reveal steadier tool operation and fewer interruptions, especially when paired with the right cordless tools.

Smart charging options for flexible recharging

This battery supports two practical charging paths so you can recharge where you are, not where the charger lives. Use AstroAI’s proprietary charger or connect a USB-C cable to top up the pack on the go. Note: the charger and USB-C cable are not included in the package.

• Dual charging options foster convenience at home, on-site, or during travel
• USB-C recharging enables compatibility with portable power sources and laptops in a pinch

A built-in BMS helps monitor conditions and protect the pack, while overheat, overcharge, and short-circuit protections help safeguard equipment and users. Real-time LED indicators keep you informed about remaining power.

• Great reliability for families, trips, or outdoor use
• LED indicators make monitoring power quick and easy

Real-world uses and a handy power bank feature

Beyond powering cordless tools, the USB output lets you charge small devices during travel or emergencies, turning the battery into a portable power bank when needed. Its rugged design and protection features may contribute to longer service life in demanding environments.
