4PCS LF280K 3.2V 280Ah Prismatic LiFePO4 Battery Cell


LF280K LiFePO4 battery cells can be connected in parallel and in series, which is perfect for off-grid solar power systems and outdoor applications such as emergency power supply, RV, camping, boat, etc. You can DIY your own battery pack with our battery cells, if you are a beginner, we also provide free instruction for you.

This LiFePO4 battery has better performance than the acid-lead battery with the same capacity, which can provide more power in daily use. On the other hand, our rechargeable battery offers 5000+ cycles (10 times longer), almost a decade life compared to 200-500 cycles and 3 years of life in a lead-acid battery. 2000-3000 cycles longer than other LiFePO4 batteries on the market.

Main feature:

  • Each battery is tested for voltage and internal resistance. And balance all RV batteries to ensure the car battery internal resistance, voltage and capacity are fully matched and balanced before delivery. This process is very necessary.
  • The typical estimated lifespan of lithium motorcycle batteries is 10 to 15 years and 4000 to 6000 charge cycles. The charge cycle is the entire cycle of operation from fully charged to fully discharged to fully charged.
  • The 3.2V 280AH deep cycle solar battery is easy to install, including the required golf cart battery, connector and screws. No skills are required and it can be assembled in 10 minutes. And a lifepo4 battery comes with a set of busbars and screws (e.g. if you buy 4pcs batteries, we will send 4pcs cells with 4 sets of busbars and screws).
  • 280 AH Class A lithium RV batteries with Multi-Protect safety system ensure your safety and protect the lithium iron phosphate battery used. (No leakage problem)
  • Applications: engine starting battery, electric bike/motorcycle/scooter, golf cart/stroller, power tools, solar and wind energy systems, RV, caravan, backup systems and UPS, flashlight LED emergency light.
