Battery compatibility issues:
Cause: The newly installed 45AH battery may be incompatible with the original battery in voltage, capacity or type.
Solution:
Check whether the added battery voltage is the same as the original battery. If the voltages are different, it may cause the meter to flicker.
Try to replace the afterloaded battery with the original battery and see if it can solve the problem.
Problems with the battery itself:
Reason: The battery added later may have internal faults, such as broken grid or short circuit.
Solution:
Use a multimeter to measure the battery voltage to confirm the health of the battery. The voltage of a healthy battery should be higher than 12V.
If there is something wrong with the battery, it is recommended to replace it with a new battery of the same model.
Line connection problem:
Cause: The battery connection cable may be loose, damaged or have poor contact, resulting in unstable current and flashing instrument.
Solution:
Check whether the battery connection cable is loose or damaged to ensure the normal connection.
If the instrument flashes when riding on a bumpy road, it may be a poor line contact. It is recommended to go to the repair shop for inspection and maintenance.
Vehicle controller problem:
Cause: If the vehicle controller harness is loose or the vehicle CAN communication is abnormal, the instrument display may be abnormal.
Solution:
Check whether the wiring harness of vehicle controller is loose and ensure the connection is firm.
Check whether the vehicle CAN communication is normal. If there is any abnormality, it is recommended to contact professional maintenance personnel for inspection and maintenance.
Battery management system (BMS) problems:
Reason: Battery Management System (BMS) is an important part of lithium battery vehicle, which is responsible for monitoring battery status and controlling battery charging and discharging. If there is a problem with the BMS, it may cause the instrument to flicker and make it impossible to drive.
Solution:
Check whether BMS works normally. If there is any abnormality, it is recommended to contact professional maintenance personnel for inspection and maintenance.
