Model: Hanery 18650-3S2P-4000
The Hanery 18650-3S2P-4000 is a versatile workhorse, doubling the capacity of a standard 3S pack by utilizing a 6-cell (3S2P) configuration. Delivering a strong 11.1V output alongside a substantial 4000mAh capacity, this pack provides the sustained power and extended endurance needed for professional power tools, portable lighting towers, and rugged enterprise tablets operating through a full shift.
Substantial 4000mAh Capacity: Greatly extends operational life for high-voltage portable devices.
6-Cell (3S2P) Architecture: Distributes the load efficiently, improving thermal management and overall pack longevity.
Precision Cell Matching: All six cells are meticulously sorted to ensure identical internal resistance and capacity for balanced performance.
Advanced Protection Circuit: Integrated BMS safeguards against faults while actively balancing the 3 series connections.
Flexible Geometric Layouts: Can be arranged in a 2×3 block, a flat 1×6 line, or custom shapes to fit your device’s chassis.
Durable Spot Welding: Uses pure nickel strips for secure, low-resistance connections able to handle demanding continuous currents.
