Feature:1. [BALANCE DETECTION] Battery active balance module, when the voltage difference value is greater than 0.1, the chip will automatically balance detection.2. [BALANCE CURRENT] The greater the voltage difference, the greater the balance current, the maximum balance current is 2A, with active BMS balance type.3. [APPLICABLE BATTERY] Lithium battery active equalizer board, suitable for 3.2V 3.7V battery pack, with low power consumption, stable and reliable performance.4. [3 BALANCE MODE] The battery active equalizer module has 3 adjustable balance modes, which are easy to operate and have strong practicability.5. [APPLICABLE SCENES] This active balancer equalizer can be used for model toy battery repair, and can also be used with BMS long term fixed battery packs.Specification:Item Type: Battery Active EqualizerProduct Model: CF 4SZDJH2A ABalanced Dropout: <10mVBalance Current: <2ABMS Balance Type: Active BalanceApplication: Suitable for 3.2V 3.7V Battery PackWorking Power Consumption: <10mA3 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 Battery Equalizer Module1 x Connecting Cable
