NITECORE NL2160HPi 21700 Battery - 6000mAh 3.6V 20A i-Series Smart Battery with Dual Polarity Output (Same Side), Built-in Protection Board for Heavy-Duty Flashlights & High-Drain Devices (1 / 2 Pack)
Description
【Product Description】
The Ultimate Power Source for NITECORE i-Series Devices. The NITECORE NL2160HPi is a next-generation 21700 smart battery that redefines performance for high-end tactical flashlights. Offering a massive 6000mAh capacity and an impressive 20A continuous discharge current, it delivers the raw, unrelenting power needed for heavy-duty searchlights and demanding outdoor gear.
What truly sets the NL2160HPi apart is its revolutionary Same-Side Dual Polarity Output. Unlike standard batteries where positive and negative terminals are on opposite ends, the NL2160HPi features both terminals on the same end. This eliminates the need for wiring to the negative terminal, drastically reducing internal resistance, minimizing energy loss, and allowing for direct, high-efficiency power transfer to your device.
Built for extreme durability, it features a triple-layer protection system: a custom high-performance protection board (with premium MOSFETs), a pressure safety valve, and a high-strength plastic protection bracket for the circuit board. With a lifespan of over 500 charge cycles and 100% mercury/lead/cadmium-free, this battery is a safe, reliable, and eco-friendly upgrade.
( CRITICAL NOTE: This battery is specifically designed for NITECORE i-Series devices (e.g., SRT7i). It features a unique same-side polarity design and is NOT compatible with standard 21700 flashlights or devices that require traditional opposite-end terminals. Please verify your device's compatibility before purchasing!)

【Frequently Asked Questions (FAQ)】
Q1: Can I use this battery in a standard 21700 flashlight?
A1: NO! The NL2160HPi features a revolutionary same-side dual polarity output, meaning both terminals are on the same end. This is a unique design specifically for NITECORE i-Series devices (such as the SRT7i). It is NOT compatible with standard flashlights or devices that require traditional opposite-end terminals. Please verify your device's compatibility before purchasing!
Q2: What is the advantage of same-side dual polarity?
A2: It drastically reduces internal resistance and eliminates the need for wiring to the negative terminal. This provides direct, high-efficiency power transfer, reduces energy loss, and allows for maximum power output to your device.
Q3: Is this battery safe for my high-power flashlight?
A3: Absolutely. The NL2160HPi features a triple-layer protection system, including a built-in high-performance protection board, a pressure safety valve, and a high-strength plastic bracket. It is specifically engineered for safe and reliable operation under heavy loads.
Q4: How long can I store this battery without using it?
A4: With its low self-discharge characteristics, the NL2160HPi maintains its charge for extended periods, making it perfect for emergency kits and seasonal devices.
Q5: What charger should I use?
A5: Use a dedicated intelligent Li-ion charger rated for 3.6V/4.2V cells. Match the charger to your specific pack configuration.
