24V 200Ah LiFePO4 Battery
HelithTech
Product Description
Product: 24V 200Ah Lithium Iron Phosphate (LiFePO4) Energy Storage Battery
Voltage: 24 Volts
Capacity: 200 Ampere-hours (Ah)
Chemistry: Lithium Iron Phosphate (LiFePO4)
Energy Density: LiFePO4 batteries are known for their relatively high energy density, allowing them to store a significant amount of energy in a compact size.
Key Features:
Long Lifespan: LiFePO4 batteries typically have a longer cycle life compared to other lithium-ion chemistries, making them suitable for applications requiring frequent charge and discharge cycles.
Safety: LiFePO4 chemistry is known for its improved safety characteristics, including higher thermal stability and resistance to thermal runaway. This makes the battery safer to operate and less prone to overheating.
High Discharge Rate: These batteries can provide a relatively high discharge current, making them suitable for applications requiring sudden bursts of power.
Low Self-Discharge: LiFePO4 batteries have a lower self-discharge rate compared to some other battery types. This means they can hold their charge for longer periods when not in use.
Application: This battery configuration, with its 24V voltage and 200Ah capacity, is commonly used in energy storage systems for residential, commercial, and industrial purposes. It can be integrated with renewable energy sources like solar panels or wind turbines to store excess energy generated during peak production for later use.
Cycle Life: LiFePO4 batteries can typically endure a high number of charge and discharge cycles before experiencing significant capacity degradation.
Maintenance: LiFePO4 batteries generally require less maintenance compared to some other battery types, which contributes to their overall cost-effectiveness.
Charging: These batteries require a suitable charging profile to ensure optimal performance and lifespan. Charging systems should be designed to match the battery's specifications.
It's important to note that these specifications provide a general overview, and specific technical details such as internal resistance, charge and discharge rates, and protection circuitry may vary based on the manufacturer and design of the battery. If you're considering using or purchasing this battery, it's advisable to consult the manufacturer's datasheet or technical documentation for precise information.
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 this lithium battery, it's important to observe the following precautions:
Charging Profile: Ensure that the charging profile used for this battery matches its specifications. LiFePO4 batteries require specific voltage and current limits during charging to prevent overcharging and maintain longevity.
Temperature Management: Monitor and control the operating temperature of the battery. LiFePO4 batteries perform best within a certain temperature range, and extreme temperatures can affect their performance and lifespan.
Discharge Rate: While LiFePO4 batteries can handle higher discharge rates, avoid excessive discharges that could lead to reduced cycle life or potential damage to the battery.
Balancing: In multi-cell configurations, ensure proper cell balancing to prevent overcharging or undercharging of individual cells, which can impact the overall performance and lifespan of the battery.
Protection Circuitry: Check if the battery has built-in protection circuitry, including overcharge, over-discharge, short-circuit, and temperature protection. This enhances safety and prevents potential hazards.
Compatibility: Confirm that the battery is compatible with your intended application, whether it's a solar energy system, backup power, or other use. Improper usage can lead to suboptimal performance or safety risks.
Installation: Properly install the battery following manufacturer guidelines, especially if it involves connecting multiple batteries or integrating them with a larger system.
Ventilation: Ensure proper ventilation in the battery storage area to dissipate heat and maintain a suitable environment for the battery's operation.
Maintenance: Follow recommended maintenance procedures provided by the manufacturer, such as periodic checks for signs of wear, abnormal behavior, or any visible damage.
Transport and Storage: If transporting or storing the battery, follow transportation regulations and guidelines to prevent physical damage, short-circuiting, or exposure to extreme conditions.
Consultation: When in doubt, consult the manufacturer's documentation, technical support, or a qualified professional for guidance on proper usage, maintenance, and troubleshooting.
Remember that while LiFePO4 batteries offer improved safety compared to some other lithium-ion chemistries, responsible usage and adherence to guidelines are essential to maximize their performance, lifespan, and safety.
