QSO MB56 Lifepo4 628AH 680Ah 660AH Cell Eu Lfpo4 3.3 M56 628 680 Ah 3.2V 560Ah 638Ah Lifepo4 Lithium Iron Phosphate Battery Pack

The nominal capacity is Over 628Ah and the nominal voltage is 3.2V. 3.2 * 628 = 2.010 kWh, Therefore, the energy of a single cell is approximately 2.009 kWh, which is twice that of 314 Ah and 2.24 times that of 280 Ah. This is the most crucial advantage, significantly enhancing the energy density.

Under an 80% depth of discharge (DoD) condition, the cycle life can exceed 8,000 times (according to the test standard IEC 62619). This means that even if a charge-discharge cycle is performed once a day, it can be used for over 20 years (theoretical value), resulting in a higher long-term investment return rate (ROI).

System efficiency improvement, operation and maintenance reduction: Significantly reduces the number of connection components and sampling points in the battery cabinet. The energy storage system built based on MB56 cells can reduce 50% of maintenance components and 30% of the total life cycle maintenance labor costs, making operation more convenient and economical.

Yes, low-temperature performance is one of its key features. It can discharge normally at temperatures as low as -30°C, with a good capacity retention rate, which solves the problem of limited usage of lithium iron phosphate batteries in cold regions.

We offer clear warranty policies and a localized technical support network. In case of any issues, quick responses can be provided via hotline or online support. When necessary, professional technical engineers will be arranged for 1-on-1 special handling.

We have a clear after-sales process: 1:Contact our customer service by email or phone and describe the problem phenomenon. 2:Our technical support team will conduct a remote diagnosis and guide you on simple troubleshooting.3. If it is determined to be a quality issue, overseas warehouse return and exchange services will be provided.For non-human-caused problems within the warranty period (accidents and the like are usually not covered by the warranty), we will bear the repair costs.

BMS provides overcharge protection to prevent damage to the battery cells, overdischarge protection to avoid deep discharge and battery damage, overcurrent and temperature protection to prevent circuit overheating (for example, 0°C - 45°C during charging), and automatically intervenes when the temperature is too high. Battery balancing: ensures that the voltages of all battery cells remain consistent, thereby extending the overall lifespan of the battery.
