Standard charging voltage : 3.65V Absolute charging voltage : 3.75V Standard discharge voltage :2.5V Absolute discharge voltage : Maximum 2.0 V 3.2V 280Ah Lifepo4 Battery Cells Differences Between EVE280 and EVE280k EVE280 The lifespan of the cycle: ≥4000 cycles (100% DOD) EVE280k The lifespan of the cycle: ≥6000 cycles(100% DOD) If buy 4pcs battery,we will send 4pcs cells with 4 sets bus bars and bolts Self-discharge : 3.5% / month Connection: M6 bus bar & screws : Included delivery time: 3 - 7 normal days Read more We provide original Battery cells with intact QR Codes and Grade A performance. A protection valve builds inside the battery, keep the battery safe from overcharge and over-discharge use. Each battery has its own QR-code as identification. Using laminated production technology, LiFePO4 Battery has higher performance in charging, discharging, and life cycle, with a thinner body, lighter weight, more flexible size, and shape, which can adapt to a variety of applications, has better stability and tolerance in high-temperature discharging. Our Battery included all parts for assembling, with bus bars, and screws. All these parts are made of copper and aluminum, with a strong conductivity and longer life. Read more
