About this item

  • Lithium Iron Battery: LiFePO4 lithium battery life far exceeds that of traditional lead-acid batteries, with a cycle life of 2000~5000 times, 8 to 10 times that of lead-acid batteries. Its energy density is higher, capacity is doubled and weight is reduced by 30%. No memory effect, keep the power stable when idle, not affected by the previous discharge state.
  • Intelligent Management and Safety Protection: Built-in BMS intelligent management system prevents overcharging, over-discharging, over-current and short-circuit with excellent self-discharge rate. High temperature cut-off function ensures charging safety. It is safer and more reliable compared to lead-acid batteries without ground protection.
  • Convenient for capacity expansion: Supports parallel and series connection, maximum four batteries can be connected in series up to 48V, and four in parallel up to 800AH, which can realize capacity and voltage expansion at the same time, and is suitable for different needs.Only batteries with the same voltage and capacity purchased within six months can be connected in parallel or series.
  • Widely Used Scenarios: Suitable for home energy storage, UPS backup, lighting, monitoring, power tools, electric vehicles and other fields. Whether indoors or outdoors, it is your indispensable energy partner.

Q: What is the charging speed of this 300Ah LiFePO4 lithium battery?
A: This 300Ah LiFePO4 lithium battery adopts high efficiency charging technology, which can complete the charging in a shorter period of time, greatly improving the efficiency of use. However, in order to ensure the battery performance and life, it is recommended to follow the recommended charging method and current.

Q: Will the performance of this battery be affected in a low temperature environment?
A: Although LiFePO4 lithium batteries outperform conventional lead-acid batteries at low temperatures, at very low temperatures (e.g., below -20°C), the discharge performance of the battery may be somewhat affected. In order to maintain the best performance, it is recommended to preheat the battery properly or take other insulation measures when using it in cold environments.

Q: How to store this 300Ah LiFePO4 lithium battery properly?
A: To ensure battery performance and safety, it is recommended to store this 300Ah LiFePO4 lithium battery in a dry, cool and ventilated place, avoiding direct sunlight and high temperature environments. Also, direct contact between the battery and metal objects should be avoided to prevent short circuit and damage. During storage, the battery status should be checked regularly to ensure battery safety.

Q: How can I tell if this 300Ah LiFePO4 lithium battery needs to be replaced?
A: When you find that the charging speed of this 300Ah LiFePO4 lithium battery is significantly slower, the discharge time is shorter, or the battery is bulging, leaking, and other abnormalities, it may be a sign that the battery needs to be replaced. In addition, if the battery has been in use for a long time (e.g., beyond the recommended service life), it is also recommended to consider replacing it with a new one to ensure the normal operation of the device.

Q: Can this 300Ah LiFePO4 lithium battery be used during charging?
A: It is not recommended to use this 300Ah LiFePO4 lithium battery while charging. Although some devices support use while charging, doing so may cause damage to the battery and shorten its life. To ensure optimal battery performance and safety, it is recommended to use the device after charging is complete. Also, during the charging process, avoid exposing the battery to high temperatures or humidity to ensure a safe and stable charging process.
