With a cell voltage of 3.7 Volts, these batteries are perfect for microcontrollers such as used in the mBot V1.1.
Built into the battery is an over-voltage, over-current, and minimum voltage protection circuit which makes them even easier to use, although care must be taken when using LiPo batteries. Incorrect charging, usage, or physical damage to the battery can result in a fire. Be sure to only use a specific LiPo charger.
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.
Remember that like any power source, you should be extra careful not to short the power pins as doing so can damage your battery and cause it to swell/overheat, rendering it unusable and dangerous.
