Feature:1. Suitable Battery Type: The working voltage of this balance board is 1.84.5V, suitable for NCM ternary polymer lithium battery, lithium iron phosphate battery, lithium titanate battery.2. Low Resistance: The active equalizer adopts ultra low internal resistance MOS, 2OZ copper thickness PCB, provides efficient balance work and stable performance.3. Low Current: The balance current is 05.5A, the more balanced, the smaller the battery current, reserved for the wiring position of the sleep switch, the working current is less than 0.1mA, and the balance voltage accuracy is within 5mv when in sleep power off mode.4. Parallel Available: The quiescent current is about 7mA, battery capacity is recommended to be used between 30200AH, large capacity battery can connect multiple equalizers in parallel.5. Under Voltage Protection: The balance board features under voltage sleep protection, will automatically stop and enter sleep status when B1 voltage NCM LFP is less than 2.7V or LTO is less than 1.8V, standby power consumption is less than 0.1mA.Specification:Item Type: Active EqualizerMaterial: PCBWorking Voltage: 1.8-4.5VApplication: Power tool, scooter, wheelchair, bike.Package List:1 xActive Equalizer2 x Terminal CableNote:1. Before connecting the balance wire to the balance board, be sure to check whether the connection of each part of the battery pack is correct, and insulate the bottom of the board and the battery string connection terminals, otherwise, it will short circuit and burn the board.2. This balance board is backward compatible by default. For example, if it is used for 15S, the last line B16+ is empty, use for 14S, B16+ and B15+ vacant no wiring.
