Lithium battery active balance energy fer board Lithium battery active equalizer high-efficiency energy fer balance. Capacitive energy fer equalization board (high precision 5mv, whole group equalization, not adjacent equalization). Working voltage 1.8V-4.5V, suitable for ternary lithium, lithium iron phosphate, lithium titanate. Working principle, the capacitive fit fers the charge porter, the equalization board is connected to the battery to start the equalization work, the ultra-low internal resistance MOS, 2OZ copper thickness PCB, equalization current 0-5.5A, the more the battery is, the more the equalization current is Small, reserved for the dormant switch wiring position, the dormant power-off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv! The quiescent current is about 12 mA, and it is recommended that the battery capacity is between 60-300 AH. With under-voltage sleep protection, the voltage automatically stop entering the sleep state when the voltage is lower than 3.0V, and the standby power consumption is less than 0.1 mA. Colour: black Material: PCB Package Contents: 1 * Equalizer Energy fer Board (4 strings) Only 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. The measurement allowed error is +/- 1-3cm.
