Electric bicycles are currently widely used non-motorized vehicles, and they have become a common means of daily transportation for people. The lifespan of an electric bicycle largely depends on the quality of its battery. If the battery is new, the electric bicycle can travel many kilometers, and vice versa. Some batteries naturally degrade simply due to long years of use and repeated charging and discharging, while others degrade abnormally due to improper use. Now, let'sElectric Vehicle Battery Connector ManufacturerLet's talk about how to properly use batteries.

1. Remove the battery from the battery case.

Battery compartments all have a box or case. For safety, the sides of the box are always locked. If you try to forcibly 'pull' without unlocking, it’s easy to 'jam' and tear the battery case. First unlock, then pull out the battery case. Generally, battery cases have 'sliding tracks.' When taking out the battery case, let it 'slide out' parallelly. Otherwise, if you pull it and damage the box, it won’t close properly, and touching the battery can damage the battery casing or injure the battery!

The battery case is in two halves, held together by screws. Use a screwdriver to 'loosen' the screws of the battery case one by one. Once you open the battery case, you will see the batteries! Use a 50w~60w electric soldering iron to solder off each connection point of the old batteries. If it's hard to solder, add a bit of solder wire. Once fully melted, the connection wires will come off smoothly!

2. Correctly install the new battery.

First, check the battery connection wires—whether the copper core wires have discolored or turned black, whether the insulation layer is damaged, whether the fuse and fuse holder show signs of burning, and whether the discharge hole wiring is securely connected... Replace them if necessary to prevent hazards caused by poor electrical contact, sparking, short circuits, or disconnections, which could result in burns, a short circuit between the positive and negative terminals, or spontaneous combustion.

A standard battery consists of four cells in a series. The soldering iron should have a power of 50w to 60w. When soldering the battery terminals, do not exceed three seconds. First, tin the battery terminals and also tin the ends of the connecting wires; then the wire ends can quickly 'stick' to the battery terminals. Excessive heat conduction can cause some damage to the battery. After soldering, wrap the battery terminals with insulating tape to prevent the wires from being worn, pulled off, or broken during bumpy rides. Do not invert the battery, and do not press the connecting wires at the battery terminal ends.

After the batteries are connected, use battery cartons or rubber spacers to separate each battery. This not only prevents the batteries from moving back and forth, but also gives each battery space to dissipate heat from each other! Use screws to "seal" the battery box to prevent water from leaking in due to poor sealing, which is harmful to the batteries. When installing the batteries onto the vehicle, if the battery box moves around in the sliding groove, you need to find a way to fix it. Otherwise, if the battery box shakes, the batteries will shake along with it, which can easily cause leakage and affect the batteries' lifespan!

3. Check if the brake power cut is present.

For the sake of safety and saving battery power, electric vehicles have a function called 'brake power cut.' It cuts off power before braking, which is safe and does not waste electricity. Inside the brake lever, there is a small switch. When the brake lever is pressed, the switch pops out, signaling the controller to cut off the power. When the brake lever returns to its original position, the switch closes, and power is restored normally. However, if the brake power cut fails, it should be repaired. Braking without cutting power can be harmful; some customers accelerate while holding the brake, causing a large current discharge. This not only damages the battery but also places a heavy load on the controller and motor. Therefore, when replacing the battery, it is necessary to check whether the brake power cut is still functioning.

The above are the methods for extending battery life introduced by the editor. I hope that after reading, it can be helpful to everyone. The battery is the power of an electric vehicle. If the battery is used improperly, causing its lifespan to be greatly shortened, it will significantly increase the cost of using the electric vehicle. However, if you know the correct way to use the battery, you can greatly avoid battery wear.
