●Advantages of the new 2+1+5 lithium battery connector

▶ Analyze the features and advantages of the 3+10-pin stackable battery pack connector:

＞ 1. Feature Analysis

● Terminal Configuration and Stacking Design

√ Terminal Layout: A hybrid 3-pin + 10-pin layout is adopted to meet the dual requirements of the battery pack for signal control and power output.
√ Stacking Function: The structural design enables "stackable plug/socket connection," supporting the expansion of multiple battery packs in series or parallel, flexibly adapting to battery systems with different capacity requirements.

● Structure and Protection Design

√ Housing Material: Black engineering plastic housing (such as PA66, PBT, etc.) balances lightweight design with mechanical strength, meeting the shock and vibration resistance requirements of industrial applications.
√ Sealing Performance: Adopting an IP protection rating design (such as IP65/IP67), the product features a sealing ring and a plug-in self-locking mechanism for waterproof and dustproof protection, ensuring electrical safety in extreme environments (such as outdoor and humid environments).
√ Mounting Method: Multiple mounting holes (such as three) support panel and onboard mounting, adapting to different device layouts.

● Electrical and Performance Parameters

√ Current Carrying Capacity: The 10-pin terminal block is designed for high-current power transmission, with a single terminal capable of handling tens of amperes, meeting the high-power requirements of electric vehicles and energy storage devices.
√ Voltage Rating: Adapts to the voltage range of power battery systems (such as lithium-ion battery packs) (e.g., 12V to 72V and higher), ensuring electrical compatibility.
√ Contact Reliability: The terminals utilize a spring-loaded or self-locking contact structure, achieving self-cleaning and low contact resistance during insertion and removal, ensuring stable signal/power transmission over long-term use.
▶II. Advantage Summary

● Electrical Adaptability and Compatibility

√ The 3+10-pin hybrid terminal block layout simultaneously supports both signal control (e.g., BMS communication and protection signals) and power output (e.g., high-current discharge), eliminating the need for additional interfaces and simplifying system design.

Stacking functionality supports both series and parallel expansion of battery packs, flexibly adapting to energy storage systems of varying capacities (e.g., a single battery pack for small devices, multiple stacked packs for large devices), reducing hardware modification costs.

● Reliability and Safety

√ Sealed Protection: IP-rated waterproof and dustproof, eliminating moisture and dust corrosion and short-circuit risks to the terminals, extending connector life.
√ Plug-in Life: Through precision mold processing and optimized terminal structure, the plug-in life can reach thousands of times (some high-end products exceed 10,000 times), meeting the needs of high-frequency charging and discharging scenarios.

▶ Industrial Application Compatibility

Environmental Adaptability: The plastic housing's weather resistance (UV and aging resistance) and high mechanical strength enable long-term stable operation in complex environments such as outdoor and industrial sites.

Easy Installation: The multi-hole design enables quick fastening, simplifying device assembly and maintenance.

Standardized Design: Industry-standard models are plug-and-play compatible, reducing compatibility risks in system integration.

● The core value of this connector lies in its combined design of "hybrid terminals + stacking + industrial-grade protection." It precisely meets the requirements for efficient and safe power transmission between battery packs and devices/chargers in applications such as electric vehicles, energy storage devices, and portable power supplies, balancing power requirements, environmental adaptability, and cost control.
