7.4V 5000mAh (2S2P) Lithium-Ion Rechargeable Battery Description
**Overview:**
This 7.4V 5000mAh rechargeable lithium-ion battery pack is designed to provide a robust and dependable power source for a variety of electronic devices. Its configuration and specifications ensure a balance of high capacity and adequate voltage for demanding applications.
**Key Features:**
1. **Voltage:** The battery operates at a nominal voltage of 7.2 volts. This voltage is achieved by connecting two 3.6V lithium-ion cells in series (2S configuration).
2. **Capacity:** With a capacity of 5000mAh, the battery can supply 5000 milliamperes of current for one hour or proportionally less current over a longer period, providing extended operational time for devices.
3. **Configuration:**
– **2S2P:** This denotes a configuration of 2 cells in series (2S) to increase the voltage and 2 cells in parallel (2P) to double the capacity. This setup ensures both higher voltage and greater capacity, combining the benefits of both series and parallel connections.
4. **Chemistry:** Lithium-ion (Li-ion) batteries are favored for their high energy density, low self-discharge rate, and long cycle life, offering significant advantages over other rechargeable battery types.
5. **Rechargeability:** This battery is designed to be recharged multiple times, making it a cost-effective and environmentally friendly power option.
6. **Protection Circuit:** Often included is a built-in protection circuit module (PCM) that safeguards against overcharging, over-discharging, and short circuits, thereby enhancing the battery’s safety and lifespan.
**Applications:**
– Portable electronics (e.g., tablets, high-end cameras)
– RC vehicles and drones
– Medical equipment
– Backup power systems
– DIY electronics and robotics projects
**Safety and Handling:**
– **Charging:** Utilize a charger specifically designed for lithium-ion batteries. Do not exceed the recommended voltage and current levels during charging.
– **Discharging:** Prevent the battery from discharging below its safe limit, typically around 3.0V per cell.
– **Storage:** Store the battery in a cool, dry place, avoiding exposure to extreme temperatures and humidity.
– **Handling:** Handle the battery with care to prevent physical damage. Avoid short-circuiting, puncturing, or incinerating the battery.
**Dimensions and Weight:**
The exact dimensions and weight will depend on the specific design and housing of the battery pack. Generally, lithium-ion packs are compact and lightweight, but the 2S2P configuration will be larger and heavier than a 2S1P configuration due to the additional cells.
**Conclusion:**
The 7.4V 5000mAh (2S2P) lithium-ion rechargeable battery pack is a versatile and powerful energy solution suitable for a wide array of applications. Its combination of high voltage and capacity ensures extended usage time and reliability for devices that require consistent and durable power sources. This battery pack is ideal for users needing a dependable and efficient power supply for both everyday and specialized electronic devices.
