1. Symbol Description Do not place near open fire or flammable materials. A potential hazard exists when the equipment is working. Wear personal protective equipment during operation. Warning electric shock. Power off the equipment before any operation. Grounding: indicate PE cable connection position. Do not place in areas accessible to children.
2. Safety Precautions Alert It is important and necessary to read the user manual carefully (and attachment) before installing or using battery. Failure to do so or to follow any instruction or warning in this document can result in electrical shock, serious injury, and death, or damage battery, potentially rendering it unusable. When battery is stored for a long time, it is required to charge once every 6 months, and the SOC should be no less than 50%.
It is prohibited to connect battery with different types of battery. Do not connect battery to faulty inverter. Except for personnel from Company or other authorized personnel, batteries shall not be opened, repaired or disassembled.The company shall not bear any liability or responsibility caused by violation of any safety operation or design standard, production standard, equipment safety standards or any other standards or requirements.

BMS Status Warning Over Current Over Voltage Under Voltage Over Temperature Under Temperature Protect Over Voltage Protection Under Voltage Protection Short Circuit Protection Over Current Protection Over Temperature Protection PROTOCOL (Note: The protocol list is read from the BMS motherboard. The following is a case study, taking into account the contents of each BMS motherboard.)Based on the list, change the protocol.
4.7 Sleep Mode The system enters a low-power mode when any of the following conditions is met: 1.The monomer or overall over release protection is not removed within 30 seconds. 2.Press the button (3~6S) and release the button. 3. The lowest unit voltage is lower than the dormancy voltage, and the duration reaches the dormancy delay time (at the same time, meet the no communication, no protection, no equilibrium, no current).
Capacity≥50% Batteries shall be charged according to 5.1 and discharged in Discharge At 0 ℃ : accordance with the above mentioned temperature. The Discharge Character discharge capacity shall meet the standard. Batteries shall be capacity≥80% stored for 6~8 hours at the test temperature. At 25℃...
