Difference of LF280 and LF280K


1.Dimension(Height and Tabs Distance)


Height:


LF280: 204.8*72*173.6mm VS LF280K: 207*72*173.6mm


Tabs distance:


LF280: 90±0.3mm,  LF280K: 123.0±0.3mm


2.Cycle Life


LF280: 3500cycles,   LF280K: 6000cycles


(Under the 300kgf clamp, after standard charged and 30mins rest, discharge to 2.5V cut-off with the current of 0.5CA at (25±2)℃, 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)


3. Max. charge / discharge current


LF280: 1C,  LF280K: 2C

Highlights

Compared with traditional AGM/lead acid batteries, LiFePO4 battery/ Lithium iron phosphate batteries are:

  • Higher safety and stability:non-toxic, non-polluting, no rare earth metals, no explosion, no fire.
  • Long service life:10 times lifespan extended to 2000-4500 cycles.
  • 1/4 lighter than lead-acid batteries.
  • The LFP battery can work in a wide temperature range from -20 to +75°C
  • No memory effect. Can be charged on demand without loss of capacity.
  • Suitable for RV, ship, home storage, telecommunication (base station battery)
  • High energy density up to 1C-280A discharge
