Acebeam 21700 5600mAh High Capacity Rechargeable The ACEBEAM 5600mAh 21700 rechargeable lithium-ion battery is built for flashlights and other compatible devices that demand substantial capacity and stable power delivery. With a 5600mAh capacity, this protected 21700 battery is designed to support longer flashlight runtimes while providing the power needed for demanding applications. Whether you’re putting together an EDC setup, preparing outdoor gear, keeping emergency lighting ready, or replacing a compatible flashlight battery, the AB21CP56 combines high capacity with a robust, safety-focused construction. For devices with higher power requirements, the AB21CP56 provides a 15A continuous discharge current and a 20A burst current. This allows the battery to deliver ample, stable power for consistent high output in compatible equipment. ACEBEAM incorporates an integrated protective circuit using high-power MOS FETs designed to cut off when protection is activated. Multiple layers of protection include overcharge, over-discharge, over-voltage, over-current, short-circuit, and overheat protection. Safety measures extend beyond the electronic protection circuit. The battery incorporates pressure relief valve protection, separate microporous protection, and a built-in PTC cathodal block. Its steel shell riveting is designed to help avoid short circuits triggered by collision or impact, while gold-plated surfaces are used for added durability. These internal and external safeguards make the AB21CP56 a strong choice for compatible flashlights used for EDC, work, outdoor activities, travel, and emergency preparedness.
