EJC 200AH 12.8v 2.56kwh LiFePo4 Portable Solar Battery

The Solar EJC 200AH 12.8V 2.56kWh LiFePO4 Portable Battery is a high-capacity, reliable, and durable energy storage solution, designed for use in solar power systems, RVs, marine applications, and backup power setups. Here’s a breakdown of its main features, functionality, and advantages:

Key Features:
LiFePO4 (Lithium Iron Phosphate): This type of battery offers significant advantages over traditional lead-acid and other lithium-ion batteries. LiFePO4 is known for its safety, thermal stability, long cycle life, and efficiency. It’s less prone to overheating and provides a much longer lifespan than conventional batteries.
Safety and Stability: LiFePO4 chemistry is highly resistant to thermal runaway and doesn’t overheat easily, making it one of the safest lithium battery types on the market.
200Ah (Amp-Hours): This indicates the battery can supply 200 amps of current for 1 hour, or a smaller current (e.g., 20 amps) for a longer duration (10 hours). The high amp-hour rating allows for extended use with high-demand devices.
2.56kWh Energy Storage: The total energy storage capacity is 2.56 kilowatt-hours (kWh), which provides a substantial amount of power for off-grid applications, such as running household appliances, charging devices, or powering solar systems.
12.8V Nominal Voltage: This is the standard voltage for many solar and off-grid power systems, making it compatible with most 12V inverters, solar charge controllers, and DC appliances.
2,000 to 5,000 Charge Cycles: LiFePO4 batteries typically have much longer lifespans compared to traditional lead-acid batteries. This battery could last up to 10 years, depending on usage. After thousands of cycles, the battery still retains around 80% of its original capacity.
High Depth of Discharge (DoD): LiFePO4 batteries can be discharged up to 80-100% without causing damage, unlike lead-acid batteries, which should ideally not be discharged beyond 50% to avoid shortening their lifespan.
Efficient Charging: The battery’s efficiency is close to 100%, meaning that almost all the energy used to charge it is stored for later use, minimizing energy loss during charging.
BMS for Safety: The internal BMS protects the battery from overcharging, over-discharging, overheating, and short-circuiting. This system ensures the battery operates safely and optimally under various conditions, extending its lifespan.
Cell Balancing: The BMS also performs balancing across the battery cells, ensuring they charge and discharge evenly, further enhancing performance and longevity.
Lightweight Design (compared to lead-acid): Despite its high capacity, LiFePO4 batteries are much lighter than their lead-acid counterparts, making them easier to transport and install in mobile applications such as RVs, boats, or portable power stations.
Optimized for Solar Applications: This battery is well-suited for integration into solar power systems, either as the primary energy storage unit for off-grid living or as part of a hybrid setup for backup power. It stores solar energy efficiently, delivering power during times when sunlight is not available.

Applications:
Perfect for use in off-grid solar power systems, it stores solar energy for use at night or during periods of low sunlight, ensuring a steady supply of power.
Suitable for powering appliances in RVs or boats, offering long-term reliability and the ability to run high-demand devices like refrigerators, air conditioning, or lighting systems.
Acts as a backup during grid outages, powering essential electronics, lighting, and communication systems.
Provides a portable power source for outdoor adventures, allowing you to run small appliances and devices while off-grid.

Performance Estimate:
LED Lights (10W): Can run about 256 hours.
Laptop (50W): Approximately 51 hours of operation.
Refrigerator (150W): About 17 hours of power.
Small AC Unit (500W): Roughly 5 hours of usage.

Benefits:
Longer Lifespan: With thousands of charge/discharge cycles, this battery can last significantly longer than lead-acid batteries, providing better long-term value.
High Efficiency: The near-100% energy efficiency and high depth of discharge make this battery ideal for frequent use in solar and backup applications.
Safe and Stable: LiFePO4 chemistry ensures higher safety, reducing the risk of overheating, fire, or explosion, and the BMS further enhances operational safety.
Low Maintenance: Unlike lead-acid batteries, LiFePO4 does not require regular maintenance or equalizing charges.
