The 51.2V 314Ah LiFePO4 battery has an ultra-long service life and is a cost-effective choice for household energy storage. Under standard room temperature and 80% depth of discharge, its cycle life reaches 6000-8000 times, far better than traditional energy storage batteries. Calculated by daily household charge and discharge frequency, it can work stably for 12-15 years. Equipped with an intelligent BMS protection system, it prevents overcharging, overdischarging and short circuits to reduce core loss. Its monthly self-discharge rate is less than 2% with low attenuation during long-term idleness. It requires no frequent maintenance and reduces replacement costs, perfectly adapting to long-term household energy storage needs.
