1. The capacitor fit fers the charge mover, the equalization board is connected to the battery, and the equalization is started. 2. The new ultra-low internal resistance MOS, 2OZ copper thickness PCB 3. 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! 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 3.0V, and the standby power consumption is less than 0.1mA. Accessory Type:Charger Accessories Model Number:JW-DR APPLICATION:Solar System EV E-bike Working voltage: 1.8V-4.5V Suitable 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 on color:Black Material:plastic Package Contents: 1 x 4S Active Equalizer Balancer Only the above package content, other products are not included. Note: Light shooting and different 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.
