1. Compatible with Ternary Polymer Lithium Batteries and Lithium Iron Phosphate BatteriesThe active equalizer is specifically designed for use with ternary polymer lithium batteries and lithium iron phosphate batteries, ensuring compatibility with a wide range of battery types. The operating voltage range is 7V–4.2V. 2. Efficient Energy Transfer with Flying Capacitor Technology: This balancer board employs a flying capacitor charge transfer mechanism to initiate balancing, enabling efficient energy transfer and equilibrium within the battery pack. It features ultralow internal resistance and 57g copper thickness for performance. 3. Balancing Current of 0–5A and Precise Voltage Accuracy: The balancer board provides a balancing current of 0–5.5A, with a focus on lower current for equilibrium. It boasts a precision balancing voltage accuracy within 5mV, ensuring accurate and effective battery cell balancing. 4. Undervoltage Sleep Protection for Battery HealthTo safeguard battery health, this active equalizer is equipped with an undervoltage sleep protection feature. When the battery voltage of the B1 section drops below 7V, it automatically enters sleep mode, consuming less than 0.1mA standby power, thereby extending battery lifespan.
