This professional internal connection harness is built with JST SFHR-02V-R 2-pin connector and 1.8mm pitch terminals, specially designed for compact lithium battery packs. It provides stable, low-resistance electrical connection between battery cells, battery management systems (BMS) and internal modules, meeting the strict safety and space-saving demands of lithium-ion battery assembly.
Key Advantages
Ultra-Compact 1.8mm PitchThe small 1.8mm spacing design maximizes space utilization inside slim lithium battery packs and energy storage modules, ideal for high-density cell arrangements.
Secure Anti-Loosening StructureSFHR-02V-R integrated locking mechanism ensures stable connection under vibration, effectively preventing disconnection in portable batteries and power tools.
Battery Safety OrientationFlame-retardant housing material reduces fire risks, while polarized design completely avoids reverse wiring that may damage battery cells and BMS.
Low Power LossHigh-conductivity tinned terminals minimize contact resistance and voltage drop, supporting efficient charging and discharging of lithium batteries.
High FlexibilitySoft, thin wire structure fits bending routes inside battery compartments, adapting to modular battery assembly.
