1. Lithium battery active balance energy transfer board Lithium battery active equalizer high-efficiency energy transfer balance 2. Capacitive energy transfer equalization board (high precision 5mv, whole group equalization, not adjacent equalization) 3. Working voltage 1.8V-4.5V, suitable for ternary lithium, lithium iron phosphate, lithium titanate. 4. Working principle, the capacitive fit transfers the charge transporter, the equalization board is connected to the battery to start the equalization work, the brand 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 -off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv! 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 consumption is less than 0.1 mA. Product Name: 4S Capacitive Energy Transfer Equalizer Board (with Housing) Applicable battery type : for NCM/LFP/LTO Product size : 66 x 46 x 16 mm Working range of single voltage : NCM/LFP:2.7-4.2V LTO:1.8-4.2V Balanced : The whole battery pack participates in the active balance of energy transfer at the same time Under voltage protection sleep voltage : NCM/LFP: Less than 2.7V LTO:Less than 1.8V Working temperature : -10~+60 External : No need for external supply, relying on the internal energy transfer of the battery to achieve the balance of the whole group 4S quiescent current Full state : (4.2v x 4cell) 16.8V 9mA Different production batches,the appearance will be slightly different, does not affect the use color:Black Material:PCB Package Contents: 1 x equalizer 1 x Acrylic Shell 1 x terminal wire Only the above package content, other products are not included. Note: Light reflection 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.
