- Freezing point: -50 ° C
- Refractive coefficient: 1.405
- Specific heat at 50 ° C: 0.243 Cal / g K
- Global coefficient of heat transfer at 0-150 ° C: 0.88 W / m K
- Dielectric constant at 100 Hz: 4.7 (± 0.1)

In the case of a battery pack, the BMS (Battery Management System) balancing protection circuit allows charging and discharging to be individually controlled. That is, the circuit controls that all cells are charged and discharged at approximately the same voltage. The current during charging should be limited, because the cell will "absorb" the current given to it, but a higher current than the one established by the manufacturer (generally a safe current is 1C ) can cause the cell to overheat and, in extreme cases, explode. The same relationship also applies to discharge.

The kit includes 20 basic sensors, which will help you to easily kick-start any project. The sensors are featured with a proprietary Seeed Grove connectors enabling easy connection without soldering and a comprehensive guide book with exemplary classes.

The novelty of micro:Bit v2.2 for a more lively introduction to technology for children.

The micro:bit is a pocket computer that can be encoded, customized and controlled for the implementation of digital ideas and games. It measures just 4x5cm and features a fun and easy to use design, so users can create anything from games and animations to slick stories at school, at home or anywhere - all it takes is imagination and creativity. It is fully programmable. This means that each of its LEDs can be individually programmed as can its buttons, inputs and outputs, accelerometer, magnetometer, Bluetooth 5.0 technology, microphone and speaker.

It contains a quick start guide in the same package.
