Exceptional Cycle Life for Long - Term Reliability
The ETC 280AH 3.2V battery boasts a cycle life of ≥6000 times. This extended lifespan ensures that it can withstand countless charge - discharge cycles without significant degradation in performance. For large - scale energy storage projects, such as utility - scale solar farms or grid - connected energy storage systems, the long cycle life reduces the need for frequent battery replacements. This not only cuts down on operational costs but also ensures a more stable and reliable energy supply over the long term.
Ultra - Low Internal Resistance for High Efficiency
With an internal resistance (IR) of ≤0.2mΩ, this battery is highly efficient in both charging and discharging processes. During charging, it can quickly absorb electrical energy with minimal power loss, reducing the charging time. In the discharging phase, it can deliver a stable and consistent power output, maximizing the utilization of stored energy. This high efficiency is crucial for applications where energy conservation and optimal performance are key, such as in electric vehicle charging stations or data centers with high - power demands.
Optimal Weight for Easy Installation and Mobility
Weighing 5.35kg, the ETC 280AH 3.2V battery strikes a perfect balance between capacity and portability. It is light enough to be easily installed in various settings, whether it's in a compact residential energy storage system or a large - scale industrial installation. Its manageable weight also allows for greater flexibility in deployment, making it suitable for applications that require occasional relocation, such as mobile power backup units for emergency response teams.
Wide Working Voltage Range for Versatile Compatibility
Operating within a working voltage range of 2.5 - 3.65V, this battery is compatible with a wide array of electrical devices and charging systems. It can seamlessly integrate with existing power infrastructure, eliminating the need for complex voltage conversion equipment. This versatility makes it an ideal choice for a diverse range of applications, from small - scale off - grid solar power systems to large - scale commercial and industrial energy storage solutions.
Efficient Charge and Discharge Rates with High Peak Discharge Capability
The battery has a charging ratio and a discharge rate of 1C, which enables it to charge and discharge at a reasonable pace, meeting the energy demands of most regular applications. Additionally, its peak discharge rate of 2C provides an extra boost of power when needed. This is particularly useful in scenarios where sudden high - power demands occur, such as during the start - up of high - power electrical equipment or in emergency power backup situations.
5 - Year Warranty for Peace of Mind
ETC offers a 5 - year warranty on this battery, demonstrating its confidence in the product's quality and durability. This extended warranty period gives users peace of mind, knowing that they are protected against any potential manufacturing defects or premature failures. In the event of any issues, users can rely on ETC's after - sales support to ensure a seamless experience.
