- Appearance & Protection
- The battery is fully enclosed in a blue PVC heat-shrink sleeve, providing basic insulation, moisture resistance, and scratch protection — the standard packaging for industrial lithium-ion battery packs.
2. Its neat rectangular shape indicates it is assembled from multiple cells (either 18650 cylindrical or soft-pack polymer cells) via series-parallel connections, with customizable dimensions to fit different device installation spaces.
- Specialized Wiring Design
Unlike standard 2-wire packs, this one features three wires:
- Red wire: Main circuit positive (+) terminal, responsible for power output.
- Black wires: One is the main circuit negative (-) terminal, and the other is an NTC (Negative Temperature Coefficient) temperature/signal detection wire. This connects to the BMS or device motherboard to provide real-time data on battery temperature, voltage, and status.
The pack comes pre-fitted with a white connector (most likely a JST-style plug), eliminating the need for user soldering. It can be directly plugged into matching device headers, ideal for standardized OEM/ODM projects.
- Functionality & Applications
- Key Advantage: The NTC signal detection design allows the device or BMS to monitor the battery in real time, enabling over-temperature protection, voltage balancing, and fault warning — significantly enhancing safety and reliability.
- Common Use Cases: Smart medical devices, industrial instruments, security monitoring equipment, outdoor power stations, intelligent robots, electric mobility aids, and other scenarios requiring battery status monitoring.
