LiFePO4 Battery

LiFePO4 battery, also called lithium phosphate battery, includes cylindrical and prismatic types. The cycle life is more than 2000 times with 80% left at 100% DOD.

LiFePO4 Battery PacksLiFePO4 Cell

Lithium iron phosphate is the chemistry we supply most. A LFP cell sits at 3.2V nominal and charges to 3.65V, so four cells in series give the 12.8V that drops straight into a lead acid footprint. The flat discharge curve, the 2000 cycle floor and the -20℃ to 60℃ discharge window are why solar lighting and storage customers move to it.

We supply the range at three levels. Single cells for customers who assemble their own packs, finished packs in ABS or lead acid style cases for customers who want a drop-in replacement, and rack and wall mounted 48V systems with RS485 or CAN communication for household and commercial storage.

Who It Is For

  • Solar street light and solar monitoring assemblers replacing sealed lead acid
  • Residential and commercial energy storage integrators building 48V racks
  • Golf cart, forklift, RV and light EV builders
  • UPS and backup power manufacturers

Problems It Solves

  • Lead acid packs that lose usable capacity after one or two seasons of deep cycling
  • Pole boxes and equipment bays that cannot take extra weight or a different footprint
  • Sites where the pack sits below zero at night and above 45℃ at noon
  • Battery rooms that need a communication port the inverter can actually read

Questions About LiFePO4 Battery

How many cycles does a Sunder LiFePO4 battery give?

Our published figure is more than 2000 cycles with 80% capacity remaining at 100% DOD. The 48V ESS cabinets are rated 5000 cycles at 0.2C and 70% DOD.

Can a LiFePO4 pack replace my 12V lead acid battery directly?

In most cases yes. Four LFP cells in series give 12.8V nominal and 14.6V charge voltage, and our LFP12xx packs are built in lead acid style ABS cases with F2, M5, M6 or M8 terminals. Send us the case size and terminal you use now.

Do you sell cells on their own?

Yes. Cylindrical IFR18500, IFR18650, IFR26650, IFR32600, IFR32700 and IFR42110, and prismatic cells from 10Ah to 300Ah are all available as bare cells.

What is the charge voltage for a LiFePO4 cell?

A LFP cell has a 3.2V nominal voltage and is typically charged to 3.65V, which corresponds to 14.6V for four cells in series.
