1. Active Inductance Equalization: It will start when the voltage difference exceeds 0.1V, and the equalization accuracy of ±50mV is not as high as that of capacitor equalization. 2. Simple and Easy to Use: The accuracy is not as good as the balance board of the capacitor type, but it is low in price and high in cost performance among similar products. 3. Applicability: Suitable for ternary lithium batteries and iron lithium batteries. 4. Balance Current: 1.3A (balance current is related to voltage difference, the smaller the voltage difference, the smaller the balance current). 5. Balance Function: The battery module has a balance function to maintain the balance of each battery and extend the life of the battery. Specification: Item Type: Battery Active Balancer Board Product Material: Plastic Model: None Indicator Light: With Working Indicator Scope of Application: Ternary Lithium Battery, General Lithium Iron Battery Product Size: Approx. 22 x 16 x 4mm / 0.9 x 0.6 x 0.16in (2 Strings) 22 x 30.5 x 4mm / 0.9 x 1.2 x 0.16in (3 Strings) 22 x 45 x 4mm / 0.9 x 1.8 x 0.16in (4 Strings) Operating Voltage Range: 3.0V-4.5V Balance Start Condition: the Voltage Difference Between Two Adjacent Batteries is Greater Than 0.1V Balance Current: 1.3A (Balance Current is Related to Voltage Difference, the Smaller the Voltage Difference, the Smaller the Balance Current) How to Use: Indicator light description: The indicator light is on, indicating that the corresponding two batteries are being balanced, the indicator light is off, indicating that the equalization has been completed, or the pressure difference has not reached the starting conditions, and the indicator flashes, indicating that the equalization has failed to start (See Note 3). PackageList: 1 x Inductance Active Balance Board Notice:1: Start wiring from 0V in order. 0V is the total negative pole
