The dynamic balancing voltage value is 3.7V, the standby consumption current is 25uA, the overcurrent protection value is 150A/2S, and it can be activated by disconnecting the load or charging. The voltage difference for balancing is triggered by a voltage difference of 30mV/ trigger time of 0.5S, and the balancing time is cycled for 10S Good heat dissipation performance: The built-in heat sink structure quickly dissipates the internal heat of the device, reduces the temperature of core components, and avoids performance degradation or damage caused by overheating. The surface of the heat sink adopts a fin design to increase the contact area with the air and accelerate heat dissipation. Add thermal conductive materials: The bonding surface can be optionally equipped with a thermal conductive silicone gasket to fill the gap, reduce the contact thermal resistance, and increase the thermal conductivity efficiency by 30%. Insulation design to avoid the risk of short circuit in the circuit; Three-proof varnish coating, suitable for damp and dusty environments It is applicable to various scenarios: car battery start and stop, electric vehicles, emergency power supplies, and other high-power equipment scenarios. The protection board is equipped with an NTC line to monitor temperature changes in real time. It achieves 100mA passive balancing, extending the lifespan of lithium batteries and effectively maintaining the consistency of battery cells [Satisfactory Service]: We Provide 24-hour online service,If you encounter any problems, Please email SELLER SUPPORT (Not Amazon support), we will give you a perfect solution.
