1. Replace the lithium battery: take out the original battery, and contact the after-sales staff or official customer service of Hongri Company according to the battery manual to purchase and replace the appropriate lithium battery. Pay special attention to the matching of battery voltage, capacity, size and other parameters to avoid the problems caused by the inconsistency between battery and vehicle structure.
2. Determine the cause of power failure: If your vehicle has power failure, you can first check whether the power connection between the battery and the motor is loose or rusty. You can take out the battery to clean the contact points and pay attention to whether the power port is connected correctly. At the same time, check whether the accessory circuit is damaged. If it is broken, it needs to be replaced in time.
3. Check the power supply and monitor: If all the above problems have been eliminated, it may be a power failure or an electronic controller problem that leads to power failure. You can check whether the wiring of the power converter is loose or not installed firmly during wiring installation, or check whether the display of the monitoring instrument is abnormal.
It is suggested that you should be patient and careful when dealing with battery replacement or troubleshooting power supply to ensure safety and correctness. If you encounter problems that cannot be solved, it is recommended to contact the after-sales service department of Hongri Company for help as soon as possible.
