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 that can be removed if the battery pack will be mounted/placed inside a box with active cooling.
Wiring harnesses and connectors
- Discharge wire type: Multi-strand 12AWG flexible silicone insulated copper
- Gold plated discharge connector: standard XT90s (custom: EC5, Supra-X ProD6/D5, XT150, other)
- Discharge wire length (pack to connector end) +/- 100mm

Battery pack features
- Built-in passive thermal management.
- Shielded charge/discharge harness.
- LM35 Temperature Sensor, with a standard 3-pin connector (like servo cable).
- 10k NTC thermistor/sensor TDK Electronics with JST PH 2-pin connector.
- Integrated Battery Heating System (IBHS), for sub-zero applications. Requires an external (5V-2.5A) power source from PDB/BEC/etc. Connectors are customizable. The carbon pads temperature is controlled by NTC/PTC thermistors built-in. Internal power wiring includes also resettable fuse for protection from short-circuiting and overloading.
- 2 year
