Features 1、Automatic Balance: When the voltage difference between adjacent battery strings is greater than 0.1, the chip will automatically perform balance detection to balance the voltage. 2、Fast Heat Dissipation: The open design of the module helps the module to dissipate heat quickly and prolong its service life. 3、3 Anti Paint Protection: Surface coated with three anti paint for protection, so as to play a waterproof, dustproof, anti leakage effect to improve the practicality of the circuit board, safety, reliability. 4、No Energy Consumption: This equalizer module does not cause any energy loss, and the greater the voltage difference between adjacent battery strings, the greater the balancing current. 5、Main Application: This equalizer module can be used for model toy battery repair and also works with BMS long term fixed battery packs. Specification Item Type: Active Balancer Material: PCB Model: CF 8SZDJH2A A Balanced Dropout: <10mV Balance Current: <2A BMS Balance Type: Active Balance Applicable: 3.2V 3.7V battery pack Working Power Consumption: <10mA Three Adjustable Balance Modes: Press and Hold K2: A forced shutdown of active balance, into hibernation. Press and Hold the Middle Position: When the battery voltage is below 3V, turn off active balancing and sleep.
