Three Installation Instruction
3.1 Notes
1. Read the entire installation section and familiarize yourself with the installation steps
before installing。
2. Be very careful when installing the battery. Wear protective glasses for the installation
of lead-acid battery with openings。
3. Avoid placing metal objects near the battery to prevent short circuit of the battery。
4. The battery may produce acidic gas when charging, ensuring good ventilation around
the environment。
5. Please install indoors and outdoors to avoid direct sunlight and rain infiltration。
6. Phantom connections and corroded wires can cause excessive heat to melt the
insulation layer, ignite surrounding materials, and even cause a fire. Therefore, it is
important to ensure that the connectors are tightened and the wires are secured with a
binding band to avoid loose connections caused by the shaking of the wires when
moving applications。
7. The battery pack installed should match the charging voltage of the controller and the
recommended range of charging current。
