Series and Parallel Connection of Batteries

Introduction: The Xero battery allows multiple batteries to be connected in series or parallel and simultaneously in series and parallel. This allows for the assembly of different voltage systems and the expansion of battery system capacity. For example, four 12.8V200Ah batteries can be connected in series and parallel to form a 25.6V400Ah battery system.

When multiple sets of batteries are connected in series or parallel at the same time, in addition to external power lines, communication lines can be connected between the batteries, and internal communication between the batteries can better obtain battery information. One battery can be set as the host battery, and the other batteries can be set as the slave battery. The host collects all information about other slave batteries and can communicate with external devices such as inverters, display screens, MPPTs, etc.

Before connecting batteries in series or parallel, pay attention to: a). The batteries must be of the same model. When there are different models, different capacities, and different voltage platforms, series and parallel connections are not allowed; b). Ensure that all parallel wires are of identical length; c). 0.5C charging is recommended, that is, charging current = rated capacity of the battery * 0.5C; d). Before connecting the batteries in series and parallel, the voltage of each group of batteries must remain highly consistent.

It is recommended that the voltage difference between battery packs be:

• Voltage difference < 2000mV (@ 0%~95% SOC)
• Voltage difference < 1500mV (@ 96%~100% SOC)
• When battery batteries are connected in series and parallel, they will be charged and discharged as a whole system.

Parallel Usage: A maximum of 16 batteries can be used in parallel. Before connecting batteries in parallel, use a multimeter to test the voltage between the positive and negative terminals of the battery. You can also check the battery voltage through the Bluetooth app to ensure that the voltage between the batteries does not exceed 2V, which can be connected in parallel. If the voltage between the batteries exceeds 2V, each battery must be fully charged separately, left for 1 hour and then used in parallel. (see picture next page)

Parallel example: 2 x 12.8V100Ah
System voltage: 12.8V
System   capacity: 100Ah + 100Ah = 200Ah

Series Usage: A maximum of 4 batteries can be used in series. Before connecting the batteries in series, use a multimeter to test the voltage between the positive and negative terminals of the battery. You can also check the battery voltage through the Bluetooth app to ensure the voltage between the batteries does not exceed 2V. If the voltage between the batteries exceeds 2V, each battery must be fully charged separately, left for 1 hour, and then used in series. Series connection method: Connect the battery’s positive pole to the negative pole of the next battery, and so on. For example, two 12.8V100Ah batteries are connected in series.

Series example: 2 x 12V.8100Ah
System voltage: 12.8*2=25.6V
System capacity: 100Ah

Simultaneous Series and Parallel: To series batteries allow simultaneous use of batteries in series and parallel, with a maximum support of 4 series and 4 parallel applications. The connection method is: first in series, then in parallel, which means that the batteries are connected in series to form a high voltage and then in parallel to form a high capacity

Series & Parallel Eg. 16 x 12.8V100Ah
4 in series & 4 in parallel
System voltage: 12.8V x 4 = 51.2V
System capacity: 100Ah x 4 = 400Ah
System = 51.2V 400Ah

Battery Communication

Communication Terminal Connection: The series of Xero batteries have the function of communication networking between batteries. When communication with external devices is needed, the networking function can be used to enable the battery to summarise information. The battery can be used alone or used for communication networking, which is more prominent in some intelligent devices. When using this function, it is essential to understand its purpose and carefully read the following instructions for correct operation.

The battery includes a Controller Area Network (CAN) bus communication interface. Two circular M8 DIN connectors are located at the top of the battery to connect one battery (Link in) to another battery (Link out) using a CAN bus cable in a simple daisy link wire method.

Users can use an external communicated cable (optional) to connect to batteries and other devices via the CAN bus. This allows for communication between the battery and the load or charger, making it more efficient to use the battery. This is also beneficial for understanding battery faults. If you have more questions about the CAN bus, please get in touch with Invicta Lithium for technical support

For normal battery operation, the CAN bus function is not mandatory. The battery can automatically operate and protect itself; it does not require any CAN bus communication or external devices (such as external controllers) or other CAN bus connected batteries to operate. Retain the two black covers installed on the two M12 connectors to protect them from environmental influences when not in use.

Networking Method: After connecting the battery through the communication cable, it is necessary to use the Bluetooth connection method through the smart APP to network the battery

• Equipment Operation: Wiring: When all batteries are turned off, use the power line to connect the batteries in series and parallel (first in series and then in parallel); Please refer to this chapter<4.2 Parallel Use>.<4.3 Series Use>.<4.4 Simultaneous Series & Parallel Use>

• The battery connected to external devices serves as the first battery (Battery1), and we define this battery as the host, while other batteries are the slaves; The LINK OUT of host battery1 is connected to the LINK IN of slave battery2, Connect the LINK OUT of slave battery2 to the LINK IN of slave battery3; and so on. Turn on the battery power switch: switch from OFF to ON.
  

• Matching Address: After pressing the host (battery 1) reset button for 15 seconds, the indicator light will start running. After all the indicator lights are off, it means that the internal address allocation of the battery is completed;

• Attention: The battery must be connected to the power line in a series first and then in parallel mode. The communication line should first connect the first cluster of series connected batteries, and then connect the second cluster of series connected batteries; cannot mix;

• The matching address must select battery 1 as the host, and long press and hold its reset button for 15s. Do not select and press the reset button of other slave batteries. This step is particularly important as improper operation may result in battery networking failure.

Attention: The battery must be connected to the power line in a series first and then in parallel mode; The communication line should first connect the first cluster of series connected batteries, and then connect the second cluster of series connected batteries, cannot mix; The matching address must be selected battery1 as the host, and long press and hold its reset button for 10s. Cannot select and press the reset button of other slave batteries. This step is particularly important as improper operation may result in battery networking failure.

Press reset button on battery 1 once battery is wired up: The battery cannot be used normally until it is activated. Press and hold for 15 seconds (ref. Display Panel)
