4S 5A Cluster Equalizer Active BMS Board Lithium Battery Lifepo4 Battery Equalizer (With Case+Terminal Wire) _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1. Lithium battery active balance energy transfer board Lithium battery active equalizer high-efficiency energy transfer balance _x000D_ 2. Capacitive energy transfer equalization board (high precision 5mv, whole group equalization, not adjacent equalization) _x000D_ 3. Working voltage 1.8V-4.5V, suitable for ternary lithium, lithium iron phosphate, lithium titanate. _x000D_ 4. Working principle, the capacitive fit transfers the charge transporter, the equalization board is connected to the battery to start the equalization work, the new 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! _x000D_ 5. 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 will 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. _x000D_ _x000D_ Product Name: 4S Capacitive Energy Transfer Equalizer Board (with Housing) _x000D_ Applicable battery type : for NCM/LFP/LTO _x000D_ Product size : 66 x 46 x 16 mm _x000D_ Working range of single voltage : NCM/LFP:2.7-4.2V LTO:1.8-4.2V _x000D_ Balanced method : The whole battery pack participates in the active balance of energy transfer at the same time _x000D_ Under voltage protection sleep voltage : NCM/LFP: Less than 2.7V LTO:Less than 1.8V _x000D_ Working temperature : -10~+60 _x000D_ External power : No need for external power supply, relying on the internal energy transfer of the battery to achieve the balance of the whole group _x000D_ 4S quiescent current Full state : (4.2v x 4cell) 16.8V 9mA _x000D_ Different production batches,the appearance will be slightly different, does not affect the use _x000D_ color:Black _x000D_ Material:PCB _x000D_ _x000D_ Package Contents: _x000D_ 1 x equalizer _x000D_ 1 x Acrylic Shell _x000D_ 1 x terminal wire _x000D_ _x000D_ Only the above package content, other products are not included. _x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
