WHY CHOOSE EEL BATTERY?

  • Advanced production technology for battery cells

    Advanced Technology

    By adopting stacking production technology, lithium iron phosphate batteries have higher capacity, better charge and discharge performance and cycle life. In addition, the body is thinner and lighter, the size and shape are more flexible, and can adapt to a variety of applications. It has better stability and tolerance in high-temperature discharge and is extremely safe.
  • Original battery cells

    Original product

    We provide original batteries with complete QR codes and factory test reports, with the highest performance reaching A+ level. Our products are directly sourced from CATL and EVE factories, and can enjoy official quality assurance. We have 4 self-built warehouses in Europe to meet the delivery time requirements of European customers. We also have a warehouse in California, USA, shipped by FedEx, with a complete supply chain and a delivery time of 1 week.
  • Test and balance the lifepo4 cells

    Testing & Balancing

    We will test the capacity, voltage and internal resistance of all lifepo4 battery cells. The screening requirements are: the capacity must be higher than the rated capacity, and the voltage deviation must be less than 0.5V. We balance all original batteries to ensure that their internal resistance, voltage and capacity are fully matched and consistent before packaging.

Energy Storage Battery FAQS

Can I connect two assembled batteries in series?

Answer: This is not allowed. The voltage after series connection will exceed the withstand voltage of the BMS and damage the BMS.

Answer: The 48V 230Ah battery box is suitable for 230Ah square cells. The 48V 280Ah battery box is suitable for 280Ah, 304Ah, 306Ah, 314Ah square cells.

Answer:
Batteries of different capacities can be used in parallel, but the following conditions must be met:
1. Same voltage: Batteries in parallel must have the same voltage, otherwise it may cause current instability or battery damage.
2. Same battery type and structure: Batteries of different types (such as lead-acid batteries, lithium batteries) or structures (such as flooded and lean) have differences in charging and discharging characteristics and are not suitable for parallel use.
3. Capacity difference: The capacity difference should not be too large, and it is usually recommended to be within 20% to avoid imbalance during charging and discharging.
4. Charging and discharging characteristics: The charging and discharging characteristics of the battery should be similar to ensure safety and stability when used in parallel.
5. Safety: Pay attention to the safety of the battery when using in parallel, including preventing overcharging and over-discharging. It is recommended to use an equalizer to ensure balanced charging of the battery.

Answer:The battery cannot be used without BMS.
The BMS plays a vital role in lithium batteries, preventing problems such as overcharging, over-discharging, short circuit and overcurrent, thereby protecting the safety of the battery and extending its service life.
Batteries without BMS have the following risks during use:

Safety hazards: The battery may be overcharged or over-discharged, causing heat, smoke or even explosion.

Performance issues: The performance of the battery will decline and the service life will be shortened.

Answer:

It is recommended to charge the battery to 40% to 60% to avoid overcharging and discharging. And recharge it every 3 to 6 months to prevent the battery from self-discharging and causing the power to be too low.
