Feature: 1. WIDE USAGE: Active equalizer is suitable for NCM ternary polymer lithium batteries, lithium iron phosphate batteries, lithium titanate batteries. 2. RELIABLE MATERIAL: The active battery balancer adopts ultra low internal resistance MOS, 2OZ copper thick PCB board, with high stability. 3. HIGH ACCURACY: The active equalizer balances the current 0 to 5.5A, the more balanced the battery, the smaller the current, and the balance voltage accuracy is within 5mV. 4. 7MA STATIC CURRENT: The static current is about 7mA, the battery capacity is recommended to be used between 30 to 300mAH per balancer. 5. UNDERVOLTAGE SLEEPING: When the B1 voltage NCM or LFP is less than 2.7V or LTO is less than 1.8V, the equalizer will automatically stop and enter the sleep state, the standby power consumption is less than 0.1mA. Specification: Item Type: Battery Active Equalizer Material: PCB Suitable Batteries: NCM Ternary Polymer Lithium Battery, Lithium Iron Phosphate Battery, Lithium Titanate Battery . Package List: 1 x Battery Active Equalizer2 x Cable Note: 1. Before connecting the balance wire to the balancer board, be sure to check whether the connection of each part of the battery pack is correct, and do a good job of insulating the board bottom and battery string connection terminals. Otherwise, it will short circuit and burn the board. 2. This balancer board is backward compatible by default. For example, if used for 13 string, the last line B14+ is empty, for 12 string, B14+ and B13+ are suspended, no need wiring.
