12.8V 200Ah LiFePO4 Battery
HelithTech
Product Description
A 12.8V 200Ah lithium iron phosphate (LiFePO4) battery is a high-capacity rechargeable battery with specific characteristics:
1. Voltage: The battery has a nominal voltage of 12.8 volts, which is suitable for various low-voltage DC power applications, such as solar energy systems, energy storage, and electric vehicles.
2. Capacity: It offers a substantial capacity of 200 ampere-hours (Ah), indicating its ability to deliver 200 amperes of current continuously for one hour. This high capacity makes it ideal for energy storage needs.
3. Chemistry: The battery employs lithium iron phosphate chemistry (LiFePO4), known for its safety and longevity. LiFePO4 batteries are less prone to overheating, combustion, or explosions, making them a safer choice for many applications.
4. Longevity: These batteries generally have a long cycle life, allowing for thousands of charge and discharge cycles without significant performance degradation. This makes them suitable for applications that require long-term reliability.
5. Charge-Discharge Characteristics: LiFePO4 batteries exhibit relatively stable charge-discharge characteristics, contributing to system stability and performance.
When using this battery, it's essential to refer to the manufacturer's specifications and follow recommended charging and discharging guidelines for safety and optimal performance.
Battery Cell
The biggest advantage of prismatic cells is its thin profile, lightweight, and the effective use of space. Due to the rectangle shape of these cells, it can facilitate better layering and increase flexibility in the products. With big capacity, less cell assembled together makes monitoring on each battery cell instead of cell string become possible. Changing defective battery cell is feasible too when there is cell failure.

Precautions
When using a 12.8V 200Ah lithium iron phosphate (LiFePO4) battery, it's crucial to follow certain precautions and preventive measures to ensure safety and maximize its performance:
1. Charging Guidelines:
- Use a compatible LiFePO4 battery charger designed for this specific voltage and capacity.
- Avoid overcharging the battery, as it can lead to overheating or damage. Follow the manufacturer's recommended charging parameters.
2. Discharging Recommendations:
- Do not discharge the battery beyond its specified depth of discharge (DoD) to prevent over-discharge and potential damage. LiFePO4 batteries should not typically go below 20-30% DoD.
3. Temperature Control:
- Operate the battery within the recommended temperature range. Extreme temperatures, both high and low, can negatively impact the battery's performance and lifespan.
4. Ventilation:
- Ensure proper ventilation when using the battery, especially in enclosed spaces, to prevent the accumulation of potentially harmful gases in case of malfunction.
5. Physical Protection:
- Protect the battery from physical damage, such as punctures, impacts, or exposure to water, as it can compromise the battery's safety and performance.
6. Balancing and Monitoring:
- If using multiple LiFePO4 cells in a series configuration, employ a battery management system (BMS) to balance the cells and monitor individual cell voltages to prevent overcharging or over-discharging of any cell.
7. Storage Precautions:
- When storing the battery for an extended period, ensure it is at a partial state of charge (around 50%) and store it in a cool, dry place. Follow the manufacturer's recommendations for long-term storage.
8. Manufacturer Guidelines:
- Always refer to the manufacturer's instructions and guidelines for the specific battery model you are using.
9. Recycling and Disposal:
- Dispose of or recycle the battery following local regulations and guidelines for hazardous waste disposal. LiFePO4 batteries should not be discarded in regular household waste.
10. Safety Equipment:
- If you are handling the battery in a DIY setting, consider wearing appropriate protective gear, such as gloves and eye protection.
11. Emergency Preparedness:
- Be aware of the potential risks associated with lithium batteries and have appropriate fire safety measures in place, such as a fire extinguisher designed for lithium battery fires.
By following these precautions and manufacturer recommendations, you can safely and effectively use a LiFePO4 battery while extending its lifespan and maintaining its performance.
