    How long will a 400Ah lithium battery last?

    Amp-hours (Ah) represent the capacity of a battery, indicating how much current the battery can deliver over time. A 400Ah lithium battery can theoretically provide 400 ampere-hours of electricity. Under ideal conditions, this means:

    • If the battery supplies 1 amp of current, it would last for 400 hours.
    • If the battery supplies 10 amps of current, it would last for 40 hours.

    The actual runtime may vary based on factors like load efficiency, temperature, and battery age.


    How many kWh are in a 12V 400Ah battery?

    To calculate the energy capacity in kilowatt-hours (kWh), you can use the formula:
    kWh = (Ah × Voltage) / 1000

    For a 12V 400Ah lithium battery:
    kWh = (400Ah × 12V) / 1000 = 4.8 kWh

    This battery stores 4.8 kWh of energy. Some 12V 400Ah LiFePO4 batteries, like the EGbatt, Ampere Time or EG4 model, may provide slightly higher energy capacities due to specific design features, offering around 5.12 kWh.(12.8v*400Ah)


    How many watts of solar do I need to charge a 12V 400Ah battery?

    To charge a 12V 400Ah lithium battery, you would need a solar array that can deliver enough energy to match its capacity, which is 4.8 kWh (or 5.12 kWh depending on the battery model).

    For example, if you are using solar panels rated at 200 watts:

    • Under optimal conditions (peak sunlight of 5 hours per day), each panel can produce around 1 kWh per day.
    • To fully charge a 12V 400Ah battery (around 4.8 kWh), you would need about 5 solar panels (assuming 5 hours of sunlight per day and factoring in some inefficiency).

    The exact number of solar panels needed may vary depending on the sunlight conditions, solar inverter and panel efficiency.


    What is the maximum charging current for a 400Ah battery?

    The maximum charging current for a lithium battery is often 50% of its capacity, but this varies by battery type.

    • For a 400Ah lithium battery, the maximum recommended charging current is around 200A (50% of 400Ah), though some models, like LiFePO4 batteries, may safely support higher currents.

    For comparison:

    • Gel batteries typically recommend a charging current of 30–50% of their capacity.
    • AGM batteries usually support 30% of their capacity as the maximum charging current.

    Always check the battery’s specifications to confirm the recommended charging current. If you still not sure, please feel free to contact EGbatt. We would be glad to provide help for free.

      Shipping Notice

      EGBATT has set a high standard for shipping lithium batteries. As lithium ion batteries fall under DG (dangerous goods) category, they use high-quality DG boxes or DG wooden cases to pack the batteries along with thick foam. This ensures that the batteries are delivered to customers in the best possible condition and without any damage.

      We accept shipping

      • By express or Air shipping like UPS, DHL, Fedex.
      • Shipping by sea to port or to door service.
      • FAC to Customer's forwarder company in China.

      EGBATT ensures that all of its batteries meet the MSDS and UN38.3 standards. The packaging requirements for lithium batteries shipped by sea depend on the Watt-hour rating for lithium ion cells or batteries, or the lithium metal content for lithium metal cells or batteries. The packaging needs to meet UN specifications or be strong and rigid packing that can withstand the shocks, mechanical handling, and loading encountered during transport.

      Shipping Regulation

      If you are an international customer, please note that products will be shipped directly from China. To place your order, please contact odmbattery@outlook.com manually, rather than ordering on the website, as shipping costs may be inaccurate for regions outside of the USA.

      EGbatt understands the importance of proper handling and regulation compliance when it comes to shipping lithium ion batteries. We take great care to follow all regulations for sea and air shipping to ensure the safe and secure transport of these potentially hazardous materials.

      Shipping lithium ion batteries comes with specific guidelines outlined by transportation authorities, including the International Air Transport Association (IATA) and the International Maritime Dangerous Goods (IMDG) code, to minimize the risk of fire or explosion during shipping. These guidelines cover packaging, labeling, and documentation requirements, among other things. At EGbatt, we stay up-to-date with all current regulations and guidelines to ensure we are shipping our products safely and responsibly. We understand the risks involved with transporting lithium ion batteries and take the necessary precautions to minimize those risks for both our customers and our employees.
