Home Solar Power System Lifepo4 6000cycles Prismatic Batteries EV 280AH Rechargeable Battery
 
 
This is one of the best-selling lithium iron phosphate batteries in my shop, the product model is Lifepo4 280AH, it has an ultra-long cycle, up to more than 6000 life cycles; the actual capacity is higher than the specification, the resistance is lower than 0.25mΩ, and the discharge performance is good; Discharge <3%/month. Battery terminals are available in two styles for M6 through-hole terminals and solder studs. Generally, solder studs are easier to assemble. DIY battery packs of 12V, 24V, 36V, 48V or larger configurations can be made in series or in parallel. Iron-lithium batteries have many advantages and can be used for various electric vehicles, home energy storage, communication energy storage and solar energy storage off-grid needs.

1

cycle life at

25 °C

>6000 cycle @0.5C/0.5C Under the 300kgf clamp, after standard charged and 30mins rest, discharge to 2.5V cutoff with the current of 0.5C(A) at (25±2) °C, and then start the next cycle, end with the capacity decreasing to 80% of the
      initial capacity. The number of cycles is defined as the cycle life of the battery.
2

cycle life at

45 °C

>2500 cycle @0.5C/0.5C Under the 300kgf clamp, after standard charged and 30mins rest, discharge to 2.5V cutoff with the current of 0.5C(A) at (45±2) °C, and then start the next cycle, end with the capacity decreasing to 80% of the initial capacity. The number of cycles is defined as the cycle life of the battery.

capacity/nominal capacity

<70%

During the use of the battery, the battery s hall be stopped when the end of life regul ations are exceeded.
 
4 Rate discharge performance at25°C

Discharge capacity/nominal capacity×l00%

A) 0.5C(A)>100%

B) 1.0C (A)>98%

After standard charge and Ih rest, discharge to 2.5V cutoff with the current of 0.5 C (A), 1.0C (A), respectively. If the discharge capacity fails to meet the technical requirements, this test is allowed to be repeated three times
5 Discharge performance at different temperature

Discharge capacity/nominal capacity×100 %

A) 55°C>95% (Cutoff 2.5V)

B) -20°C>70% (Cutoff 2.0V)

Measure the initial capacity and state of the battery: A) after standard charge and 5h rest at 55°C, discharge to 2.5V cutoff with the current of 0.5C(A); B) after standard charge at 25±2°C and 24h rest at -20°C±2°C, discharge to 2.0V cutoff with the current of 0.5C(A).

The

capacity retention and recovery at 25°C

Capacity Retention ≥ nomi nal capacity×95 %

Capacity Recovery ≥ nomi nal capacity×97 %

Measure the initial capacity and state of the battery, after standard charge and stored for 28 days, discharge to 2.5V cutoff with the current of 0.5C (A), calculate the remaining capacity the retention can be expressed as a percentage of nominal capacity. After standard charged and 30mins rest, calculate the discharging capacity (Ah), the recovery can be expressed as a percentage of nominal capacity. The recovery is measured with discharge current 0.5C (A) with 2.5V cut-off at (25±2) °C.
