24V Brushless & Stacked Lithium™

Power That
Changes Everything™

Q: What is the difference between FLEX 24V Stacked Lithium and regular lithium batteries?

Traditional power tool batteries use cylindrical cells where electrons pass through narrow end caps, creating electrical resistance and heat. FLEX Stacked Lithium uses flat pouch cells with large surface areas, allowing 200% more power, cooler operation with Therma-Tech+ cooling, and 100% faster charging.

Q: Are all FLEX 24V tools cross-compatible with Stacked Lithium batteries?

Yes. Every FLEX 24V battery works seamlessly on every FLEX 24V cordless tool and charger in the ecosystem.

Q: How do I activate the 5-Year Extended Warranty?

All FLEX 24V tools, batteries, and chargers come with a 3-Year Limited Warranty, extendable to 5 years when registered at flexpowertools.com within 30 days of purchase.

Q: Are STACK PACK toolboxes compatible with other modular systems?

FLEX STACK PACK features its own proprietary auto-locking latching mechanism designed for maximum stability and IP65 protection.

Experience revolutionary 24V cordless power engineered for demanding jobsites. Featuring cutting-edge Stacked Lithium™ pouch-cell technology, sensor-free brushless motors with Turbo Mode, and the rugged STACK PACK™ modular storage ecosystem.

Next-Gen Battery Technology

24V Stacked Lithium™

Traditional tool batteries stack cylindrical 18650 or 21700 cells that introduce high electrical resistance and generate intense heat under heavy draw. FLEX Stacked Lithium™ uses flat, high-surface pouch cells that allow electrons to flow unrestricted.

200% More Power: Maximum sustained amperage delivery for heavy cutting and drilling.

300% Longer Battery Life: Low operating heat prevents battery cell degradation over 1,000+ charge cycles.

100% Rapid Charging: Fully recharge a 6.0Ah Stacked Lithium battery in under 30 minutes with the 550W Super Charger.
