Wire Harness and Cable Features:
Silicone cable withstands high temperature, fits heating condition during battery charge‑discharge cycles
Supports high‑current charge & discharge for battery packs, low internal resistance
High‑strength ultrasonic welding joint, durable against repeated bending and vibration
Transparent insulating sleeve covers bare copper wires to reduce short‑circuit risk during assembly
Red‑black color coding to avoid reverse‑connection mistakes
Core Advantage Properties:
✅ Nickel tabs support direct spot‑welding onto cell lugs, improve PACK assembly efficiency
✅ Anti‑aging & bend‑resistant silicone wire, suitable for long‑term operation of energy storage and e‑mobility devices
✅ Stable welding joint, resistant to shock and vibration
✅ Full‑parameter customization available for different battery module designs
Important Notes:
1. Please confirm the connector model, pin sequence and wire gauge before installation to avoid wrong connection, short circuit or equipment damage.
2. Avoid using the wire harness in over-current, over-voltage or high-temperature exceeding the rated working range, to prevent wire heating and safety risks.
3. Keep the connector away from water, dust, oil and corrosive environments to ensure long-term stable conductivity and avoid poor contact.
4. Do not bend or squeeze the wire sharply for a long time; reasonable wiring protection can extend the service life of the harness.
5. For drone and flight model applications, check the locking buckle condition before flight to ensure firm connection and prevent mid-air disconnection.
