The Nitecore 21700 Intelligent Battery System is an innovative set-up consisting of a 21700 NL2150HPi high performance i-series li-ion battery.

The patent pending, high performance i series battery features dual way output with positive and negative polarities at both ends and high energy density of up to 240mWh/g. It enables a highly efficient output by minimizing the loss of power due to internal resistance.

Technical Description

The Nitecore ML21 high CRI magnetic light module has a maximum output of 80 lumens and is ideal for either handheld or tail stand use, especially for applications such as reading and camping. The CRI value is ≥ 90 providing a warm and soft beam that reduces eye strain and provides excellent colour retention.

The kit includes Nitecore's MPB21 magnetic power bank module which turns the 21700 batery into an incredible compact battery pack. Featuring a USB port, the module combined with the battery can recharge your electronic devices when you are on the go. The MBP21 also allows the 21700 battery to be recharged and features a red indicator which flashes when in progress and stays illuminated once the cell is fully charged.

The Intelligent Battery System has a range of protective safeguards, including over-current protection, reverse polarity protection, over-charge protection and over-voltage protection.
