All-Round Protection for Peace of Mind: This protection board, specially designed for lead-acid iron lithium batteries, integrates six core protective functions: voltage protection, reverse connection protection, over-power protection, short-circuit protection, over-current protection, and over-discharge protection. Whether you are exploring outdoors, using home energy storage, or in industrial applications, it provides comprehensive security for your battery, allowing you to use it with confidence and without worry. Voltage Protection: Accurately monitors the battery voltage. When the voltage exceeds the safe range, the protection board responds quickly to automatically disconnect the circuit, preventing damage to the battery from over-voltage charging or discharging, and effectively extending its lifespan.
