Performance parameters: Specification: 8S is compatible with 1.5A for 7S. Serial : 8S (downward compatible for lower serial) Equalizing current: 1.5A maximum (different from differential pressure, internal resistance, resistance, etc., the greater the differential pressure, the greater the current) Equalization accuracy: 0.03V Applicable battery: 3.2V/3.65V/3.7V/4.2V lithium battery or lithium iron phosphate, ternary lithium universal Not applicable to: capacitor, lithium titanate battery. Balance mode: active energy transfer color: purple Material: PCB Equilibrium efficiency: 92% Equalization : in the unit of two adjacent batteries, multiple columns are synchronized Trigger condition: adjacent differential pressure 0.1V Equalizing current: 800ma Equalization stop: adjacent differential pressure Less than 0.03V Equalization period: full voltage period (including charging, discharging and idle) Low voltage protection: battery voltage is lower than 2.5V Sleep power consumption: 2uA low power consumption, battery can be idle for a long time Equalization indication: when the light is on, it means the equalization is in ; when the light is off, it means the equalization is completed; when the light flashes, it means the internal resistance of the battery is high or is dropped or suspended Built in installation: suitable for battery internal installation and long-term use Other instructions: used with the protection board or the protection board with passive equalization, without influence Wiring : take No. 0 (B -) as the negative for forward connection, without wrong sequence or reverse connection Product size: 68 x 29mm Different production batches, the appearance will be a little different, it will not affect the use Package Contents: 1 x 8S equalizing board 1 x Connecting Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
