Measure all 4 batteries in the protection state to see which battery has the lowest voltage compared to other batteries. Remove this battery and charge it with a 12 volt charger only, using a 2 amp current charge for approximately 10 hours. Once fully charged, use a 12 volt or 25 watt bulb to discharge to 10 volts. Calculate the discharge time to see if the battery can be discharged for more than 6 hours. to see if there is any improvement.
If the discharge time is too short, this section must be replaced. You can also do some experiments before replacement, such as adding distilled water and sulfuric acid to see if there is any improvement. You can also unload and reload the other sections in a single section, and repeat several times to actually calculate the power of those sections. A 20 amp-hour battery shouldbe able to discharge for 10 hours at a current of 2 amps per cell.
Lithium-ion electric vehicles are lithium battery electric vehicles, which refer to electric vehicles equipped with lithium-ion batteries. In recent years, environmental problems caused by traditional internal combustion engine vehicles and shortage of oil resources have made people turn to new energy vehicles.
Pure electric vehicles have become an important development direction of electric vehicles because they can truly achieve “zero emissions”. Lithium-ion batteries have become the ideal energy source for the new generation of electric vehicles due to their excellent performance.
The things you should pay attention to when buying a car are:
1. Confirm your ability to'purchase:
Confirm your purchasing capacity. Affecting the family's overall quality of life, it is usually based on the family's average income over the past three years. Generally, 20% of the family income from the last three years is used, but no more. 10% of the value of family assets.
2. Focus:

3. On-site confirmation:
Basically determine the models you want to purchase according to the above two steps, and go to the 4S store in person to confirm on-site, including test drive, l investigation, loan situation, repair and maintenance and other related situations.
The steps are as follows:
1. Trouve the base battery box and remove the screws securing the battery box.
2. Remove the battery connection wires one by one.
3. After removing the first set of batteries, remove the second set of batteries from the battery case.
4. Disconnect the last connection cable between the battery and the electric vehicle and remove the battery.
