Product Description


JBD-B04S003 is an active balancer specifically designed for balancing when using 3-4 series battery packs; Suitable for lithium cells with different chemical properties, such as lithium ions, lithium polymers, lithium iron phosphate, etc. The maximum balanced current is 5A. B04S003 can be installed independently or installed with Jiabaida BMS.

● When the battery pack is working, using the battery pack to supply power to the balance board can prevent a large pressure difference between the battery packs from causing abnormal power supply and damaging the battery pack power supply instrument;
●  Enable equalization after sending commands; After the balance is turned on, stop sending commands, and the control foot will close and then turn on again, then continue to turn on, and then turn off after re-powering on; After the balance board sleeps, the protection board needs to send a command to wake up before reading the balance on flag.
●  When the battery pack is working, the active equalization board will activate active equalization when it detects that the total voltage of the battery pack is higher than 13V.
●  Reserve a BMS control switch port, which can be used with a software board. The software version can control the equalization module through the I/O pin.
