Feature: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 BalancerMaterial: PCBModel: CF 8SZDJH2A ABalanced Dropout: <10mVBalance Current: <2ABMS Balance Type: Active BalanceApplicable: 3.2V 3.7V battery packWorking Power Consumption: <10mAThree 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.Press and Hold K1: Active balance is turned on (not recommended).Package List:1 x Active Balancer1 x Cable
