Model: Hanery 21700-3S1P-4500

The Hanery 21700-3S1P-4500 is a masterclass in power density. By connecting just three premium 4500mAh 21700 cells in a single series string, this incredibly compact pack delivers a robust 11.1V nominal output and a substantial 4500mAh capacity (approx. 50Wh). Achieving this exact specification with older 18650 technology would typically require a bulkier 6-cell (3S2P) configuration. This streamlined 3-cell architecture makes it the definitive, space-saving energy core for high-end professional tools, agile commercial drones, and advanced handheld medical equipment where every gram and millimeter counts.

• The 21700 Advantage: Replaces bulky 6-cell 18650 packs with a sleek, 3-cell powerhouse, significantly reducing weight and volume.

• High 11.1V Capacity: Delivers 4500mAh for exceptional runtime in a remarkably compact 3S1P format.

• Enhanced Pack Reliability: Half the cells mean half the spot welds and connections, statistically lowering the risk of failure.

• Intelligent 3-Node BMS: Crucial for series packs, the built-in BMS protects and actively balances all three cells to maximize pack longevity and safety.

• Optimal Power-to-Weight Ratio: The most efficient way to achieve significant 11.1V power, crucial for airborne or handheld applications.

• Flexible Geometries: Readily configured into a sturdy triangle, a flat 1×3 array, or an end-to-end stick to perfectly match your device’s chassis.
