DALY BMS LFP LifePo4 4S 12V 50A BMS Battery Management System for Lifepo4 Battery Pack Balanced Charging Board

The DALY BMS 4S 12V LiFePO4 PCB Protection Board is a high-performance and highly reliable Battery Management System designed exclusively for 4S (4 x 3.2V) LiFePO4 battery packs. Built to offer maximum safety and efficiency, this BMS regulates charging, discharging, temperature control, and ensures the long-term stability of your lithium iron phosphate batteries. It comes equipped with high-precision balance wiring and an integrated temperature sensor that help maintain cell uniformity and prevent thermal stress. Engineered with advanced circuitry, this BMS enhances battery lifespan, improves performance under load, and protects your battery pack in demanding applications such as solar systems, electric vehicles, energy storage units, and more.

Key Features of 4S 12V 50A BMS

• Overcharge & Over-Discharge Protection: Automatically stops charging when any single cell reaches 3.7V and stops discharging when cell voltage drops to 2.5V. This prevents damage and significantly improves battery cycle life.
• Temperature Protection: Equipped with a built-in temperature sensor, the BMS safeguards the battery in extreme thermal conditions. It activates discharging protection at 70°C and offers low-temperature protection down to -20°C.
• Short Circuit Protection: In case of wiring faults, defects, or accidental short circuits, the BMS instantly shuts down the entire battery system to prevent overheating, fire hazards, or permanent damage.
