Features

Optional.

LM35 Temperature Sensor, with a standard 3-pin JR connector.
10k NTC thermistor/sensor TDK Electronics, 2-pin JR connector
Liquid-cooling system (temperature sensors, thermistors, pipelines, pomp, external radiator) + heating module (requires an external 12V power source). No CAN Bus.

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. If the configuration is equipped with a liquid-cooling system, the battery module and hardware parts will be mounted into an ABS or aluminium box.
