Características Product Quality: Our A+grade lithium iron phosphate battery,After rigorous testing, our batteries can be deep cycled 8000+ times and have a service life of up to 10 years. SPECIFICATION:Nominal capacity:280Ah;Nominal voltage:3.2V;Nominal energy:896Wh;Energy density:≥160Wh/kg,Self-discharge/per month:≤3.0%;Internal Resistance:≤0.25mΩ; Advantages of LiFePo4:The lithium iron phosphate material itself has a high thermal decomposition temperature and generates less heat during charging and discharging, reducing the risk of thermal runaway and fire. Reliable performance: This Lifepo4 Li-Fe battery pack has a high energy density of ≥160Wh/kg, which enables efficient energy storage and utilization. With a monthly self-discharge rate of less than 3%, it ensures long-term reliable performance and is fully capable of handling a wide range of application scenarios, such as Power Supply for Solar Systems,Rvs,Golf Cart, Motor, Off Grid,New energy ships. What you'll get: 4pcs 3.2v 280ah LiFePo4 batteries, 4pcs busbars and 8pcs nuts, and great after-sales service!
