Core Features

 

  • Appearance & Protection

 

  1. The entire pack is enclosed in a blue PVC heat-shrink sleeve, providing standard insulation, moisture resistance, and scratch protection for industrial lithium-ion batteries.
  2. Its slim, elongated rectangular shape indicates it is assembled from multiple cells (typically 18650 cylindrical cells) via a custom series-parallel configuration. This form factor is tailored to fit narrow battery compartments, such as those found in electric scooters or specialized instruments.

 

  • Wiring & Connector Design


The pack is equipped with a multi-pin white connector (most commonly a PH/XH-style header) and features several red and black wires.

 

  1. This multi-wire configuration typically includes: main power positive/negative leads, voltage balancing taps, and an NTC (Negative Temperature Coefficient) temperature sensor wire. This is characteristic of packs with built-in balancing and status monitoring, allowing the BMS (Battery Management System) to manage the voltage and temperature of each cell string individually.
  2. The pre-installed connector enables true "plug-and-play" integration, reducing user wiring complexity and risk, making it ideal for OEM/ODM mass production projects.

 

  • Functionality & Applications

 

  1. Key Advantages: The multi-wire interface supports cell balancing, temperature monitoring, and fault warning. This significantly enhances the battery's safety, cell-to-cell consistency, and cycle life, making it suitable for devices requiring high power stability.
  2. Common Applications: Electric scooters/hoverboards, industrial instrumentation, security monitoring equipment, medical devices, outdoor power stations, and specialized power tools.


 Battery Advantage:

1. steady perfgormance,long cycle life,eco-friendly,light weight

2. built-in PCM protection system,with advanced imported chip

3. multiple-series connection and modularized smart design

4, Capacity, resistance, Voltage, platform time consistency is good
5, With short-circuit production function, safe and reliable
