Series and parallel connection of batteries

Introduction
The DP-series battery allows multiple batteries to be connected in series or parallel, as well as simultaneously connected 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 connect ed in series and parallel to form a 25.6400Ah battery system.

When multiple sets of batteries are connected in series and 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 ho st battery, and the other batteries can be set as the slave battery. The host collects all information ab out other slave batteries, and can communicate with external devices such as inverters, display screen s, MPPTs, etc.

Before connecting batteries in series or parallel, it is necessary to pay attention to:

  • The batteries must be of the same model. Different models, different capacities, and different voltage platforms, series and parallel connection is not allowed;
  • Ensure that all parallel wires are of the identical length;
  • 0.5C charging is recommended, that is, charging current=rated capacity of battery * 0.5C;
  • 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, it will be charged and discharged as a whole system. 4.2 Parallel usage

A maximum of 16 batteries can be used in parallel. Before connecting batteries in parallel, a multimeter needs to be used to test the voltage between the positive and negative terminals of the battery. You can u 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 batteri es exceeds 2V, each battery needs to be fully charged separately, left for 1 hour, and then used in p arallel.

EPOCH-BATTERIES-DP12120H-Lithium-Iron-Phosphate-Battery-Fig-
\(26\)

For example, two 12.8V120Ah are used in parallel

EPOCH-BATTERIES-DP12120H-Lithium-Iron-Phosphate-Battery-Fig-
\(27\)

  • System voltage: 12.8V
  • System capacity:120Ah + 120Ah = 240Ah

Do not output positive and neg ative poles on the same battery, which may damage the battery.

Serial usage
A maximum of 4 batteries can be used in series. Before connecting the batteries in series, a multimeter needs to be used to test the voltage between the positive and negative terminals of the battery. Yo u can also check the battery voltage through the Bluetooth app to ensure that the voltage between th e batteries does not exceed 2V. If the voltage between the batteries exceeds 2V, each battery needs to be fully charged separately, left for 1 hour, and then used in series. Series connection method:
Connect the positive pole of the battery to the negative pole of the next battery, and so on.

For example, two 12.8V120Ah batteries connected in series

  • System voltage : 12.8*2=25.6V
  • System capacity : 120Ah

Simultaneous series and parallel
DP 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 for ma high capacity.

Battery communication

Communication terminal connection
The series of Epoch DP 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 summarize 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 important 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.

Communication line connection method:

EPOCH-BATTERIES-DP12120H-Lithium-Iron-Phosphate-Battery-Fig-
\(30\)

User can use an external communicated cable (optional) to connect to batteries and other device via 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 contact Epoch 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.

Charging requirements

We recommend using a charging source with specific lithim charging settings to meet the following charging requirements to achieve the optimal performance and lifespan of EPOCH DP series batteries.

Note: Batteries with heating function need to be heated before switching to charging mode.

AC-DC charger
Check if the AC-DC battery charger you plan to use has a dedicated lithium charging setting that meets the above charging requirements. Many battery chargers are only designed to charge Lead-acid battery and may not have appropriate lithium charging settings.

Photovoltaic charging
Check if the solar regulator you plan to use has a dedicated lithium charging setting that meets the a bove charging requirements. The EPOCH series batteries can be charged using a solar regulator wi thout lithium charging settings. However, it must be set to charge no more than 58.4V (4 batteries in series, with a maximum charging voltage of no more than 14.6V for a single battery). After the battery is fully charged, please turn to the recommended floating voltage.

Charging with an AC generator through a DC-DC charger
Check if the DC-DC charger you plan to use has a dedicated lithium charging setting that meets the above charging requirements. You can use a DC-DC charger without lithium charging settings to charge EPOCH series batteries. However, it must be set to charge no more than 58.4V (4 batteries in series, with a maximum charging voltage of no more than 14.6V for a single battery), and then it must be turned off after the EPOCH series battery is fully charged. After the battery is fully charged, please turn to the recommended floating voltage.

Recommended charging voltage
We strongly recommend a dedicated charger for lithium-ion batteries to better fully charge the battery.
At the same time, according to the actual situation, AGM chargers can also be used to charge the battery, which can achieve varying degrees of effect.

Passive balance function
When the battery is charged close to SOC 100%, due to the chemical characteristics of lithium batteries, the voltage difference between the cells will gradually expand. In order to ensure that each cell has the same capacity, slightly higher capacity cells will be consumed, which can allow the remaining cells to catch up.

Battery recycling
Epoch® DP lithium-ion batteries are recyclable and should not be treated as household waste or landfill waste. If you need assistance in recycling batteries, please contact your dealer or Epoch.
