The battery pack rugged construction. 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. Externally is wrapped in a hard (Black & Blue) PVC film.
