As the battery battery cycle times increase, the battery capacity decay speed is inconsistent, causing the battery voltage to be seriously out of balance. Balance current:0A-5.5A, When the voltage difference = 0.1V, the balance current:1.0A, The voltage difference is proportional to the balance current. The more balanced the battery, the smaller the current, Balance voltage accuracy is within 5mv! Reserve the wiring position of the sleep switch! The working current in the sleep power-off mode is Less than 0.1mA The static working current is about 12mA The capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started.No voltage difference is required. Working principle: The capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started. The for original new ultra-low internal resistance MOS, 2OZ copper thickness PCB Equilibrium current 0-5.5A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv! The quiescent current is about 12 mA. It is recommended that the battery capacity is 60-300AH. With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1mA. For all means suitable for ternary lithium, lithium iron phosphate, lithium titanate. Note: Due to different production batches, there are slight differences between the actual product and the picture, which will not affect normal use.The color of the harness is random and cannot be specified. Type:12S Colour:As Shown Material:PCB Package Contents: 1 * Equalizer transfer board Only the above package content, other products are not included. Note: Light reflection and erent displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
