Nitecore 21700 Intelligent Battery System (MPB21 Kit): Quick Look

Nitecore have a useful little kit here with the 21700 i series battery, this is a custom cell which has both positive and negative connections on both ends. The cell can also be used in "normal" devices such as torches/flashlights.

Using a magnetic connection you can attach items to it. The MPB21 Kit comes with the ML21 Light/lantern which has an output of 80 lumens, and the MPB21 is the power bank module, turning the battery into an ultra compact power bank.

I look at this kit, show you how it works and what I think of it. There are some obvious advantages here (super compact size and you can simply get spare/replacement cells), it's small enough to carry with you anywhere or as an emergency power or light source. There are a few areas where I would make some adjustments, and I discuss this in the video.
