CFE S, S Pro series Battery Series & Parallel Guidance

1. Batteries cannot be used in mixed batches, only the same batch can be used in series or parallel
2. Each battery must be fully charged before the batteries are connected in series or in parallel, and the voltage difference of the battery pack should be within 100mV
3. When the battery is under voltage, the BMS will perform shutdown protection. At this time, press the switch on the display, and the display will light up, but the battery has no output at this time; you can connect the battery to the inverter to charge or use the charger to charge and activate the battery , and the display switch can also wake up the battery.
4. During the battery charging process, the charging mode will change from CC to CV, and when the OLED display shows full power, the mode will automatically switch to CV mode. After the battery is fully charged, it will automatically enter the balance state. Do not remove the charger at this time and continue to charge the battery until the OLED display voltage is 14.6V (12.8V battery)/29.2V (25.6V battery)
5. The maximum current of the battery system used in series or parallel is 100A
6. When the batteries are used in series or in parallel, the DIP switches must be set correctly according to the user manual. Confirm all the power cables and communication cables are connected correctly, then the load can be connected. Finally, according to the order from the last slave battery to the master battery, turn on the battery in turn, please be sure to start the master battery at last (the power cables should be as thick as possible and has good conductivity, the contact surface of the connection is large, and there is no looseness, etc.)
7. When the batteries are used in series or in parallel, the battery which connected to the positive pole of the load is used as the master battery, other batteries are slaves, and the negative pole of the last slave is connected to the negative pole of the load.
8. Do not press the button to turn off any battery or change the DIP switch during use, If you want to change the mode, please turn off all the batteries in turn according to the power-on sequence, and finally disconnect the load. Then you can reset the mode according to the user manual
PCS Recommended charging and discharging protection threshold parameters:

12V system PCS recommended charging voltage for series connection is 3.55V x 4 =14.2V, discharge cut-off protection voltage is 2.85V x 4 =11.4V
24V PCS recommended charging voltage for series connection is 3.55V x 8 =28.4V, discharge cut-off protection voltage is 2.85V x 8 =22.8V
48V PCS recommended charging voltage for series connection is 3.55V x 16 =56.8V, discharge cut-off protection voltage is 2.85V x 16 =45.6V
If the PCS can not set the calculation of voltage accuracy to the decimal place, the unified decimal place to fix the round up, such as: 11.4V according to 11V, 45.6V according to 46V adjustment

Remarks: S series can only be used in series, S Pro series can be used in series or parallel, S series and S Pro series batteries cannot be connected in one system, The batteries need to be fully charged before connecting in series; when using the LFP S Pro Battery, you need to connect the communication cable (485) and adjust the DIP switch (DIP)

Description and operation process of Active Balancing mode:

|

The premise of using the Active Balancing mode: the voltage difference between each battery in the system before series or parallel ≥ 0.3V
Cut-off condition of Active Balancing mode: the voltage difference between each battery in the system is less than 0.1V
Connect the batteries in parallel according to the parallel mode, no need to connect the inverter, ensure that the parallel cable, communication cable, and DIP settings are all correct, for all connected battery, turn DIP switches 2, 3, and 4 upward; 1, 5, 6, 7, 8 down. In the order from the last slave battery to the master battery, turn on the batteries and enter the Active Balancing mode.

Instructions and operating procedures for single battery use mode:

| When the battery leaves the factory, it will be configured as a single battery by default, and the setting mode is the dial 1234 up and 5678 down.

If you need to use single battery only, please make sure that the dial setting is correct before use, otherwise it will not turn on

Series or Parallel battery use mode:

| Please refer to the instructions for the 1234 dial position of the DIP switch, and the 5678 dial position is always down.
