1. The capacitor fit transfers the charge mover, the equalization board is connected to the battery, and the equalization is started.2. The new ultra-low internal MOS, 2OZ copper thickness PCB3. Equilibrium current 0-55A, the more balanced the battery, the smaller the current, with manual sleep switch, sleep current mode is less than 01mA, the balance voltage accuracy is within 5mv 4. The quiescent current is about 12 mA. It is recommended that the battery capacity is 60-300AH.5. With under-voltage sleep protection, the voltage will stop automatically when the voltage is lower than 30V, and the standby consumption is less than 01mA.Accessory Type:Charger AccessoriesModel Number:-APPLICATION:Solar System EV E-bikeWorking voltage: 18V-45VSuitable for ternary lithium, lithium iron phosphate, lithium titanate.Balanced Cascading: Support balanced cascading for battery packs, for example , it can cascade for 11S , 24S ,36S , 48S....and so oncolor:BlackMaterial:plasticPackage Contents:1 x 4S Active Equalizer BalancerOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
