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. 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. Applicability: Suitable for ternary lithium batteries and iron lithium batteries. Balance Current: 1.3A (balance current is related to voltage difference, the smaller the voltage difference, the smaller the balance current). Balance Function: The battery protection module has a balance function to maintain the balance of each battery and extend the life of the battery.
