The 8KWh household LiFePO4 battery boasts an ultra-long service life with over 10,000 charge-discharge cycles, far exceeding lead-acid and ternary lithium batteries, supporting long-term and high-frequency use. It has low charge-discharge loss, high energy conversion efficiency and slow capacity attenuation, serving stably for more than ten years. Featuring a modular and durable structure with impact and aging resistance, it requires no complicated daily maintenance. Suitable for daily household energy storage and matched with solar photovoltaic systems, it replaces frequently replaced traditional equipment, greatly cutting household power and replacement costs with high cost performance.
