Continuous Equalization Mode: Press the negative (white) self-locking switch to start continuous equalization mode.Continuous equalization for an extended period requires manual stopping.The longer the equalization time, the better the effect.In continuous equalization mode, the LED flashing status is: the positive LED flashes, and the negative LED remains on.2. Timed Equalization (1 Hour): Double-click the positive (black) switch to start the one-hour timed equalization mode.The active equalizer begins equalization; it automatically stops after one hour.In timed equalization (1 hour) mode, the LED flashing status is: the positive LED flashes rapidly, and the negative LED remains off.⚠⚠Precautions👉Measurement Method for Equalizing Current:Because the equalizing current is affected by the loop resistance, connecting an ammeter will increase the loop resistance and reduce the equalizing current. Therefore, it is not recommended to use a connected ammeter. Furthermore, disconnecting the equalizing circuit during normal equalization operation will damage the equalizer. Therefore, current testing must be performed using a DC clamp-on ammeter.👉Equalization Time Issues:▶Under the same battery internal resistance, if the system can operate at the maximum equalizing current, the equalization time will be shorter; the lower the resistance of the connecting wires and connectors, the shorter the time.▶High-capacity battery packs will have a longer equalization time.▶The smaller the equalization voltage difference, the longer the time.▶Equalization is performed in the final stage, where the voltage difference is very small, resulting in a very small current, hence this period also takes longer.▶When using active continuous online equalization, the equalization state is more ideal, and the battery voltage difference can be controlled between 10mV-20mV. In this method, time is not a concern.👉Equalizer Heat Generation: Under normal battery conditions, the equalizer generates minimal heat. When the battery pack malfunctions and a voltage difference approaches 2V, the inverter will operate under overcurrent load conditions, generating heat which is released by the heat sink.👉Voltage Difference Between Battery Strings After Equalization:▶The minimum voltage difference designed for the 504/508/513/516/524/804/808/813/816/824 series is ≤15mV (actually achievable at 10~20mV);▶The minimum voltage difference after equalization is related to the equalization time; the longer the equalization time, the smaller the voltage difference;▶The minimum voltage difference after equalization is related to the battery's internal resistance, the resistance of the connecting wires, the resistance of the connectors, and other circuit parameters; the lower the resistance, the smaller the voltage difference.📦📦Package List: Active balance board, wiring sequence detection board, high-temperature resistant silicone ribbon cable, 3.81mm terminals, flathead screwdriver, product manual
