The Ultimate NITECORE i-Series Power Station!
We have combined the high-performance UMS4 4-Slot Fast Charger with 4x NL2160HPi 21700 6000mAh 20A batteries into one perfect bundle. This kit provides everything you need to keep your NITECORE i-Series devices (such as the SRT7i) running at peak performance.
The UMS4 is a QC 2.0-enabled smart charger that delivers up to 4000mA total output (3000mA max per slot) and features 4 independent slots with a high-definition LCD display for real-time monitoring. You can charge all four batteries simultaneously, ensuring your entire gear fleet is always ready for your next adventure.
Paired with the NL2160HPi, a 21700 battery with a massive 6000mAh capacity and an impressive 20A continuous discharge that features a revolutionary Same-Side Dual Polarity Design (both terminals on the same end), this bundle is the ultimate power solution for extended outdoor trips, emergency preparedness, and heavy-duty applications.
( CRITICAL NOTE: The NL2160HPi features a Same-Side Polarity design and is ONLY compatible with NITECORE i-Series devices (e.g., SRT7i). It is NOT a standard 21700 battery and will not work with other flashlights. Please verify your device's compatibility before purchasing!)
