This is the highest energy density currently in production.
Each cells outputs a nominal 3.7V at 2000mAh!
This battery comes terminated with a standard 2-pin JST-PH connector - 2mm spacing between pins.

Do not attempt to charge these with anything but a charger specifically designed for Lithium Ion batteries.

Battery includes built-in protection against over voltage, over current, and minimum voltage.

Note: Although these cells are rated for 2C continuous discharge, the wiring and connectors are only rated up to 1A, so be sure to take that into account when determining your power requirements.
