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.
