Description and operation process of parallel equaliza-
tion mode:
1. The premise of using the parallel balance mode: the voltage difference
between each battery in the system before series or parallel ≥ 0.3V
2. Cut-off condition of parallel balance mode: the voltage difference between
each battery in the system is less than 0.1V
3. 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 parallel balance 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.

Remarks: SRAYSTECH LFP Battery can be used in series or parallel, The batteries need to be fully charged before
connecting in series; when using the RAYSTECH LFP Battery, you need to connect the communication cable (485)
and adjust the DIP switch (DIP)
