1. The capacitor cooperates with the transfer charge pusher, the balance board is connected to the battery, and the balance is started. 2. new ultra-low internal resistance MOS, 2OZ copper thick PCB 3. Balance current 0-5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current 4. The current mode is less than 0.1mA, and the balance voltage accuracy is within 5mv 5. Quiescent current is about 12mA. The recommended battery capacity is 60-300AH. With under-voltage sleep protection, it will automatically stop when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA. Applicable to all devices suitable for ternary lithium, lithium iron phosphate, and lithium titanate.
