The Nitecore NL2160HPi is a high-capacity, high-discharge 21700 Li-ion rechargeable battery, specifically designed to power Nitecore's "i Series" flashlights and other high-drain devices. It's a crucial component for achieving the maximum performance (especially high lumen output) from compatible Nitecore products.

Here's a breakdown of its key characteristics:

• "i Series" Specific Design: The "i" in HPi signifies that this battery is part of Nitecore's innovative "i Series" intelligent battery system. The most distinctive feature of these batteries is their dual-way output with positive and negative polarities at both ends. This unique design minimizes power loss due to internal resistance, allowing for highly efficient power delivery, especially for demanding flashlights that draw high current. It also simplifies the internal design of the flashlights themselves.

  • Compatibility Note: Due to this unique dual-polarity design, NL2160HPi batteries are generally ONLY compatible with Nitecore "i Series" flashlights (e.g., P10iX, P20iX, P35i, SRT7i, i4000R, TM12K, etc.). They are typically NOT compatible with conventional 21700 batteries or chargers that don't support the "i Series" system.

• High Capacity: It boasts a substantial 6,000mAh (milliamp-hour) capacity at 3.6V (21.6Wh). This large capacity translates to significantly longer runtimes for compatible devices, particularly high-power flashlights.

• High Continuous Discharge Current: The "HP" in HPi stands for "High Performance," indicating its ability to deliver a high continuous discharge current of 20A (Amperes). This high discharge rate is essential for powering flashlights that produce extremely high lumen outputs, as these require a considerable amount of power quickly.

• Protected Battery: The NL2160HPi includes an integrated intelligent protection circuit. This circuit safeguards the battery against common issues such as:

  • Overcharging

  • Over-discharging

  • Short-circuits

  • Over-current

  • Pressure equalization (prevents explosions)

  • Temperature protection

• Rechargeable and Durable:

  • Like other quality Li-ion batteries, it's designed for over 500 charge cycles, offering years of reliable use.

  • It features a durable button-top design.

• Dimensions:

  • Diameter: 21.9mm ± 0.3mm (0.86" ± 0.01")

  • Length: 77.5mm ± 0.3mm (3.05" ± 0.01")

  • Weight: Approximately 79g (2.79 oz)

• Environmental Friendliness: It's designed to be mercury, lead, and cadmium-free.

• Compatible Chargers: While specifically for "i Series" flashlights, it can be recharged in compatible Nitecore chargers such as the UMS4, UMS2, Ci4, and Ci2.

In essence, the Nitecore NL2160HPi is a specialized, high-performance 21700 Li-ion battery that provides extended runtime and robust power output for Nitecore's "i Series" flashlights, distinguished by its dual-polarity design and integrated safety features.
