Ensure the battery is matched by model/specification and firmly fixed in the battery compartment to prevent loosening during use.

The terminals of battery connection wires must be equipped with insulating sleeves to avoid short circuits caused by exposed metal contacts.

A fuse of corresponding specification must be connected in series in the positive line of the battery connection wire for overcurrent protection.

Before installing the battery, carefully check for cracks on the battery case and signs of leakage. Do not use damaged or leaking batteries.

During wiring, arrange the battery connection wires neatly to avoid entanglement or extrusion and prevent wire abrasion.

Strictly follow the color-coded wiring: the red wire from the controller connects to the battery's positive terminal (red terminal), and the black wire connects to the battery's negative terminal (black or blue terminal) to ensure an effective series connection.
