FLEX's 24V Stacked Lithium battery delivers 200% more power and 300% longer life than traditional lithium, fully charging in just 35 minutes, according to FLEX Power Tools. The drastic improvement allows professionals to complete more demanding tasks without frequent battery swaps or prolonged downtime, fundamentally altering workflow efficiency on job sites.

Cordless tool users expect gradual improvements in battery technology, but FLEX's Stacked Lithium platform offers a dramatic leap in power, run-time, and charging speed that redefines expectations.

Companies that fail to innovate their battery technology to match or exceed FLEX's stacked lithium will rapidly lose market share among professional users, pushing the industry towards higher-performance, more efficient battery designs.

Why FLEX's Stacked Lithium Redefines Performance

The FLEX 24V Stacked Lithium battery delivers 200% more power and 300% longer battery life with THERMA-TECH™+ heat management compared to traditional lithium, according to FLEX Power Tools. It charges 100% faster, fully powering up in just 35 minutes. The 10.0Ah platform offers industry-dominating power and performance. Its Stacked-Lithium pouch cells have far greater capacity than DeWalt's, as noted by Pro Tool Innovation Awards. The platform is 100% cross-compatible with all FLEX 24V tools and chargers. This makes it ideal for professional tradespeople needing maximum power, extended run-time, and rapid charging for demanding applications.
