The **LHZ-226-R** typically refers to a high-capacity, rechargeable Lithium-Ion (Li-ion) battery pack or cell, often utilized in specialized industrial equipment, robotics, or high-drain consumer electronics. Below is a breakdown of the electronic specifications and characteristics associated with this part. ### 1. Key Technical Specifications The "226" in the model number often corresponds to the chemical composition or physical dimensions (frequently a 22650 or similar cell size). | Parameter | Typical Value / Description | | :--- | :--- | | **Chemistry** | Lithium-Ion (Li-ion) | | **Nominal Voltage** | 3.7V (Standard) / 7.4V (If 2S configuration) | | **Capacity** | Often ranges between 2000mAh to 2600mAh | | **Discharge Rate** | High-drain capability (C-rating varies by brand) | | **Cycle Life** | 300 - 500 Charge/Discharge cycles | | **Protection** | Usually includes a built-in PCM/BMS (Protection Circuit Module) | --- ### 2. Internal Electronic Components A professional-grade battery like the LHZ-226-R is rarely just a raw cell. It contains internal circuitry to ensure safety and longevity: * **Protection Circuit Module (PCM):** * **Overcharge Protection:** Prevents the cell from exceeding 4.2V, which could lead to thermal runaway. * **Over-discharge Protection:** Cuts off power if the voltage drops below ~2.5V to prevent permanent chemical damage. * **Short Circuit Protection:** Instantly disconnects the terminals if a short is detected. * **PTC (Positive Temperature Coefficient):** A hardware fuse that increases resistance if the battery overheats, effectively throttling the current. * **CID (Current Interrupt Device):** A mechanical pressure valve that breaks the circuit if internal gas pressure becomes too high. ### 3. Physical & Connection Interface The "-R" suffix often denotes a specific configuration or connector type: * **Wire Leads:** Red (Positive) and Black (Negative) 22AWG or 24AWG wires. * **Connector Type:** Commonly uses a JST-PH or JST-XH 2.54mm pitch connector for plug-and-play integration into PCBs. * **Casing:** Typically wrapped in blue or yellow PVC heat-shrink tubing. ### 4. Application Areas Because of its specific form factor and stability, the LHZ-226-R is frequently found in: 1. **Medical Devices:** Portable monitors and infusion pumps. 2. **LED Lighting:** High-intensity rechargeable flashlights or emergency exit signs. 3. **RC Vehicles:** Powering transmitters or small receivers. 4. **Smart Home Hardware:** Wireless security cameras or smart locks. --- ### Usage Safety Warning ```markdown CAUTION: Lithium-ion batteries must be charged with a dedicated Li-ion constant-current/constant-voltage (CC/CV) charger. Never exceed the maximum charging voltage or subject the battery to temperatures above 60°C. ```
