2S 1.3A Inductive Active Balancer Board

Product Description:

✨ Working Voltage Range: 3.0V to 4.5V per cell.

⛔ Compatible Battery Chemistry: Universal design supporting Li-ion (Ternary Lithium) and LiFePO4 (Lithium Iron Phosphate) batteries.

✨ Maximum Balancing Current: Up to 1.3A (Note: the actual current drops proportionally as the voltage gap between cells narrows).

⛔ Equalization Precision: Accurately balances adjacent cells to within 30mV (0.03V).

✨ Trigger Threshold: Active balancing automatically starts when the voltage mismatch between the two adjacent series cells exceeds 0.1V.

⛔ Static Power Consumption: Ultra-low standby draw, not exceeding 20µA.

✨ Operating Logic: Uses an onboard 1R0 inductor to bridge adjacent cells via high-precision switching circuits. It dynamically takes excess charge from the higher-voltage cell and pushes it directly into the lower-voltage cell, saving energy that would normally be wasted as heat by traditional passive balancing resistors.

⛔ Dimensions: Approximately 22mm x 16mm x 4mm
