3.7V 6000 mAh Lithium Batteries 21700-1S2P

3.7V 6000 mAh Lithium Batteries 21700-1S2P

The Hanery 21700-1S2P-6000 demonstrates the true advantage of the 21700 platform. By connecting just two high-capacity 3000mAh cells in parallel (1S2P), it delivers a massive 6000mAh at 3.7V. Achieving this capacity with older 18650 technology would typically require a bulkier 3-cell pack. This dual-cell configuration is the perfect high-endurance solution for rugged tablets, advanced medical monitors, and long-range IoT sensors where space is tight but runtime is critical.

  • Massive 6000mAh Capacity: Provides exceptional all-day runtime for demanding 3.7V devices.

  • Space-Saving 2-Cell Architecture: Replaces bulkier 3-cell 18650 packs, simplifying internal device layout.

  • Enhanced Pack Reliability: Fewer parallel connections mean a inherently more robust and reliable power system.

  • Precision Cell Matching: Both cells are meticulously sorted to ensure perfect balance and shared load during operation.

  • Advanced Safety PCM: Integrates high-quality protection circuitry designed to handle the larger energy reservoir safely.

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

Please note that we have a MOQ for our battery. For batteries in stock, the MOQ is 10,000 pcs. For customized batteries, the MOQ is 50,000 pcs.
