Model: Hanery 21700-2S1P-5000

The Hanery 21700-2S1P-5000 is a revolutionary power solution that demonstrates the true advantage of the 21700 platform. By connecting just two premium 5000mAh cells in series (2S1P), it delivers a robust 7.4V output and a massive 5000mAh capacity. Achieving this exact specification with 18650 technology would require a bulkier and heavier 4-cell (2S2P) pack. This streamlined 2-cell configuration is the perfect high-endurance, space-saving solution for professional handheld electronics, high-end medical devices, and powerful LED lighting where minimizing weight and volume is critical.

• The 21700 Advantage: Replaces bulky 4-cell 18650 packs with a sleek, 2-cell powerhouse.

• High 7.4V Capacity: Massive 5000mAh (37Wh) for exceptional all-day runtime.

• Enhanced Reliability: Fewer cells mean a simpler pack architecture and a statistically lower risk of failure.

• Intelligent Balancing BMS: Crucial for series packs, the built-in BMS protects and actively balances both cells for maximum longevity.

• Space & Weight Savings: The most efficient way to achieve 5Ah at 7.4V, freeing up internal device space.

• Custom Orientation: Can be assembled side-by-side or end-to-end to fit specific chassis designs perfectly.
