Thermal management

Optional

  • LM35 Temperature Sensor, with a standard 3-pin connector.
  • 10k NTC thermistor/sensor TDK Electronics.
  • 6W Integrated Battery Heating System (IBHS), for sub-zero applications. Requires an external 6V power source from PDB/BEC of the aircraft.

Safety

  • 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.

Warranty

  • 2 year
