- Innovative Passive Built-in Battery Cooling System.
- Shielded and Cooled Discharge Cable.
- LM35 Temperature Sensor, with a standard 3-pin connector.
- 10k NTC thermistor/sensor TDK Electronics.
- 6W Integrated Battery Heating System, for sub-zero applications (requires an external 6V power source from PDB/BEC of the aircraft).
- The upper part of the cell is over-insulated with a ring-shaped dielectric material.
- The entire cell block is surrounded by a multi-layers shield with mechanical strength and dielectric insulated, outside-reinforced with an aluminized film used in the spacecraft industry. All covering materials provide a high sealing, improve thermal performance and contribute to the robustness of the battery pack.
- The battery pack is externally wrapped in a hard (Black & Blue) PVC film.
- 2 year
