Key Features of the Wire Harness:
- Twisted Pair Anti-interference Design
Red and black wires are tightly twisted, effectively suppress electromagnetic noise. It ensures accurate and stable temperature signal transmission even in complex battery working environment.
- High Thermal Conductivity Sensing Patch
Flat metal patch provides fast heat transfer, responds quickly to temperature variation. It can be closely fitted on battery surface for precise temperature monitoring.
- Reliable 2Pin White Connector
White locking plastic connector features easy assembly and maintenance. Snap lock prevents loose contact caused by vibration.
Solid Soldering Connection The joint between wire and metal patch is soldered firmly, strong pull resistance, not easy to break during long-term vibration.
- Customizable Parameters
Support custom wire length, patch dimension and NTC resistance value (10K, 100K etc). Meet different lithium battery pack design requirements.
- Wide Application
Ideal for LiFePO4 / NCM lithium battery packs, portable power stations, e-bike batteries, energy storage systems, power tool battery temperature monitoring.
