Installation Guide

Preparation

• Before installation, please read all safety information provided in this document.
• If you have any questions about the operation and safe use of the battery system, please contact the technical support engineer immediately for a free consultation.

Before Operation:

• Qualified electric worker Qualification is mandatory
• Remove all metal items, such as jewellery, watch, pen
• To ensure the safety of construction personnel and equipment, disconnect the battery pack from the operating equipment during wiring
• Pay attention to the terminal voltage polarity of the battery module
• Make sure installation tools are insulated and use tools correctly
• Follow the connection port description and system connection diagram
• It is forbidden to plug and unplug when the battery is working.
• Necessary operation should be done after the power supply is disconnected
• Before the formal operation, ensure that the power terminals are properly connected and tighten the terminals; When it is necessary to measure, be careful to use instruments and tools, to avoid short circuits and other accidents
• It is strictly prohibited to disassemble the battery without permission from the professional technician from the manufacture

Appearance

Attention

• The charging current shall be less than the maximum charging current specified in the data sheet. Charging current exceeding the recommended current may damage the battery；
• The discharge current shall be less than the maximum discharge current specified in the product specifications; A Discharge current bigger than the recommended current may damage the battery；
• Non-professional personnel is not allowed to disassemble the battery；
• Reverse charging the battery is strictly prohibited；
• Battery packs should not be used or placed at high temperatures. It will cause overheating, function failure or shorter life；
• The battery pack should be placed in a dry and cool environment when it is not in use. Immersing in water is prohibited；
• It is strictly prohibited to install and disassemble the battery pack when it is live.
• For optimum performance, you must charge at 14.6V. If you do not, you will not be able to reach the full usable capacity of the battery.
• To ensure the best performance of the battery when stored for a long time, the battery should be charged and discharged every three months.
• After the battery discharge protection, it can be removed by the following ways:
  1. Let the battery stand for 15-20 min The battery will be automatically unprotected after standing for 15-20 min.
  2. Use the charger with OV charging function (It can charge the battery starting from 0V) to charge the battery. After fully charged, the battery can be used normally.
  3. Use another 12V lithium battery with the same capacity to connect in parallel with the battery and put them aside for over 12 hrs. After that, fully charge the battery and it can be used normally.
• If solar charging is used, please set the regulator to the charging mode of the B04 lithium battery.
• When charged with the controller, the controller output is used to connect the load:
• It is recommended that the controller is set as below parameters to avoid the battery failing to recover when the BMS cut off the battery for protection after a continuous small current discharge.
  • Overcharge Protection Voltage: 14.6V
  • Overcharge Recovery Voltage: 14.2V
  • Over-discharge Protection Voltage: 8.8V
  • Over-discharge Recovery Voltage: 10.8V
• The above settings can ensure that the controller triggers the protection first instead of the battery BMS, which can prolong the service life of the battery.
