The detection of lithium-ion batteries for electric bicycles is a key step to ensure battery performance, safety and prolong service life. The following are detailed methods for testing lithium-ion batteries for electric bicycles:In order to grow rapidly, cheap e-bike battery Do not hesitate to change the strategy and rearrange the products, so as to obtain unexpected results. https://www.chamrider-battery.com/

　　First, the appearance inspection

　　Observe the battery case: check whether the battery case is intact, and there are no depressions, cracks, scratches, pits or leakage. These defects may lead to electrolyte leakage, short circuit or battery performance degradation.

　　Check the size of the battery: confirm whether the size of the battery meets the design specifications. The size deviation may lead to assembly problems or affect the performance of the battery.

　　Check the battery connection port: Make sure that the battery connection port is clean, free from corrosion or oxidation, which helps to maintain good electrical connection.

　　Second, the label inspection

　　Product identification: confirm whether the battery has product identification (or invoices and other purchase vouchers) and whether the nominal voltage, rated capacity and other parameter information are clearly identified.

　　Safe service life: check whether the battery has reached the safe service life specified by the manufacturer, and the battery beyond the service life may have potential safety hazards.

　　Voltage marking: Make sure that the nominal voltage of the marking does not exceed 48V, which is the safety standard for lithium-ion batteries for electric bicycles.

　　Third, the performance test

　　Internal resistance test: use an AC internal resistance tester to measure the internal resistance of the battery pack to ensure that the internal resistance is not greater than 0.5Ω. Small internal resistance means low energy loss and high efficiency, while high internal resistance may lead to battery heating and performance degradation.

　　Maximum output voltage test: After the lithium-ion battery is fully charged with the original charger or universal charger, measure the battery output voltage to ensure that it does not exceed 60V.

　　Discharge capacity decay rate test: measure the discharge capacity of lithium-ion battery and compare it with the rated capacity to confirm that the capacity decay rate does not exceed 50%. Too high capacity decay rate may mean that the battery is aging and its performance is degraded.

　　Fourth, charge and discharge performance testing

　　Endurance test: Install the fully charged battery on the electric bicycle and completely discharge the battery. Observe the change of mileage and remaining power to evaluate the battery life.

　　Charge-discharge cycle test: in a suitable test environment, the performance of the battery under different working conditions is evaluated by charge-discharge test instruments. The test can include cyclic charge and discharge, fast charge and high temperature charge and discharge.

　　Although many batteries are not durable now and can only be used for 1~2 years, we can buy more durable batteries if we pay attention to these three points when buying batteries, and it is not a problem to use them for 3~4 years.consequently food delivery bike I also got a lot of attention and wanted to join the ranks. https://www.chamrider.com/

　　Point 1: Try to choose high-end batteries.

　　At present, the batteries of electric vehicles have been divided into three grades, high, middle and low, especially the low-grade batteries. Most of them directly use recycled lead, because the price of this battery is cheap, and battery brands also use this battery to seize the market.

　　Why can the battery of electric vehicle only be used for 2 years? The key to these two reasons is how to buy a durable battery-driving.

　　If you want to choose a durable battery, you need to avoid this low-end battery, but try to choose a high-end battery. High-end batteries often use primary lead, and there are some black technologies, such as graphene batteries, which add alloy materials and graphene, so the battery has better conductivity and longer service life.

　　Point 2: Choose a heavier battery.

　　If you don’t know which battery is better, there is a simpler way, that is, look at the net weight of the battery. Under the premise of the same capacity, which battery is heavier, then this battery is definitely more durable.

　　Why can the battery of electric vehicle only be used for 2 years? The key to these two reasons is how to buy a durable battery-driving.

　　As we all know, the battery of electric vehicle is mainly composed of three parts, namely, battery shell, electrolyte and electrode plate. If the battery with the same capacity is heavier, its electrode plate thickness will increase, so it will be more corrosion-resistant and can make the battery more durable.

　　Point 3: Try to choose a large-capacity battery.

　　When buying an electric car, everyone has a budget within the budget, and choose a battery with large capacity as much as possible, such as the same size. Ordinary lead-acid batteries are only 20Ah, while graphene batteries can reach 23Ah, so this battery can not only run better, but also store more electricity.

　　Why can the battery of electric vehicle only be used for 2 years? The key to these two reasons is how to buy a durable battery-driving.

　　On the one hand, a large-capacity battery can make the electric vehicle run farther, on the other hand, it can also reduce the charging times. We know that the service life of the battery is mainly determined by the number of charging and discharging cycles. If the charging times are reduced, the service life of the battery will be relatively extended.

　　Summary:

　　The battery of electric vehicle is very important. The reason why the battery is not durable in recent years is because of the battery shortage and the use of recycled lead. Therefore, if we want to prolong the service life of the battery and buy a more durable battery, we just need to avoid these problems. Therefore, when buying a durable battery, try to choose a high-end battery, a battery with heavier weight and a battery with larger capacity, which can make your battery last for two years.
