About this item

  • Deep Cycle Battery:LiFePO4 batteries offer a cycle life of more than 2,000 cycles compared to traditional lead-acid batteries, far exceeding the latter's 300 to 500 cycles. Its service life is 8 to 10 times longer than that of lead-acid batteries. Not only that, LiFePO4 batteries with the same capacity are lighter in weight, only 70% of lead-acid batteries.
  • Leading Lithium-Iron Technology:Deep cycle lithium-ion batteries have become the industry leader due to their high energy density, stable performance and high power performance. LiFePO4 batteries will not burn even under overcharging, over-discharging, over-current or short-circuit conditions, and they are more resistant to high temperatures without decomposition. It supports fast charging and solar panel charging, bringing more convenience for energy use.
  • Intelligent BMS:LiFePO4 batteries have a built-in BMS (Battery Management System) that effectively prevents overcharging, over-discharging, over-current and short-circuit while maintaining an excellent self-discharge rate. Built-in high temperature cut-off ensures that the charging temperature does not exceed 122°F (50°C). Lithium-ion batteries are safer and more reliable than lead-acid batteries without ground fault protection. Suitable for outdoor camping power and indoor convenient installation.
  • Flexible Capacity Expansion:Lifepo4 batteries support parallel and series connection for larger capacity and voltage. Up to 4 identical batteries can be connected in series to reach 48V, while parallel connection allows you to connect as many batteries as you need, but it is recommended not to exceed 4. Expandable up to 4 series and 4 parallel (4S4P) to provide up to 200Ah capacity and higher voltages such as 24V, 36V and 48V. Other installation methods such as 4S2P, 2S2P, 3S2P are also applicable.
  • Widely used:Li-FePO4 batteries are widely used in home energy storage systems, UPS backup, lighting, digital/CCTV cameras, portable TVs, electronic robots, electric cars, DIY speakers, 12V routers, air pumps, fishfinders, golf carts, tugboat motors, motorhomes/RVs and campers, yachts, travel trailers, garbage trailers, and many other fields to meet diversified needs.

Q: Is there any safety risk when the battery is over-charged or over-discharged?
A: Absolutely safe! The battery adopts advanced lithium iron phosphate technology and built-in BMS system, which will not burn even under extreme conditions such as overcharging, over-discharging, over-current and short-circuit, and is high temperature resistant to ensure the safety of use.

Q: How to realize the expansion of battery capacity?
A: You can increase the battery capacity and voltage by connecting them in parallel or series according to your needs. Up to 4 identical batteries can be connected in series to reach 48V, while parallel connection can be connected as needed, but it is recommended that no more than 4 be connected to maintain optimal performance.

Q: Is there a limit to the charging temperature of the battery?
A: Yes, in order to protect the batteries, we have built-in high temperature cutoff to ensure that the charging temperature does not exceed 50°C (122°F), effectively preventing performance degradation or safety hazards caused by high temperature.

Q: What is the self-discharge rate of this battery?
A: This Lithium Iron Phosphate battery has a very low self-discharge rate, which can maintain a high charge level even when it is not in use for a long time, and reduces the energy loss caused by self-discharge.

Q: How to maintain and care for this battery?
A: Maintaining and servicing this battery is very simple. Make sure that the battery is stored in a dry, ventilated, non-corrosive environment, away from direct sunlight and extreme temperatures. Regularly check the battery connections to make sure they are secure and to avoid loosening or short-circuiting. Additionally, following proper charging and discharging procedures is key to maintaining battery performance.

Q: Does this battery support fast charging?
A: Yes, this Lithium Iron Phosphate battery supports fast charging, but the exact charging speed will depend on the performance of your charger. Please use a fast charger that is compatible with the battery and follow the manufacturer's charging guidelines to ensure a safe and efficient charging process.

Q: What are the advantages of lithium iron phosphate batteries over other types of lithium batteries?
A: Compared with other types of lithium batteries, LiFePO4 batteries have higher safety, longer cycle life and better high temperature resistance. They are not easy to burn, not easy to explode, and can maintain stable performance even in high temperature environments. In addition, Li-FePO4 batteries are relatively low cost and more environmentally sustainable.

Q: What should I do with my old batteries if I need to replace them?
A: Please note that used batteries are hazardous waste and should be disposed of properly to prevent environmental pollution. You can give your old batteries to a professional recycling organization or participate in a local battery recycling program. When disposing of or transporting old batteries, please make sure they are properly packaged to prevent short-circuiting or leakage.
