Multi-group Parallel use 

If multiple systems are required in parallel, the positive terminals of several lithium-ion batteries are 
connected together, and the negative terminals connected together. The RS485 communication cables should 
also be fitted and the dip switches address codes setup (Table 2-3). Please refer to the figure below.
