1. Lithium battery is afraid of cold and heat, don't use it in extreme environment


Many people like to put lithium battery electric scooters in the sun in the summer, or park in the courtyard or on the road in winter, which is very detrimental to the service life of lithium batteries. Lithium ions are in the electrolyte and electrode pads. The migration rate is closely related to the temperature. Theoretically, the temperature can be used normally between -20℃-55℃. In daily life, the use temperature of the lithium battery between 5℃-35℃ is not harmful to the lithium battery. Users in the north Take the lithium battery home for storage as much as possible in winter, do not put it outdoors, and users in the south should avoid summer exposure.



2. Do not charge and discharge lithium batteries frequently


Many people think that the hundreds of charging cycles of the lithium battery in the electric scooter manual are just one use as long as it is plugged and unplugged. In fact, this is a misunderstanding. The manual actually refers to the number of complete heavy discharge. The lithium battery is different from the nickel-cadmium battery. , Lithium battery does not have any memory effect, can be charged anytime, anywhere. Charging when the battery has surplus power will not only shorten the service life, but also maintain the battery and extend its cycle. For lithium batteries, the correct approach is Slow charge instead of deep charge.


3. Charge with a suitable charger to avoid high current


The chemical activity of lithium batteries is much more active than lead-acid batteries, and the requirements for the charger are higher. Once you use a miscellaneous charger or an unsuitable fast charger, it will not only affect the service life of the lithium battery itself, but also cause serious overheating. The diaphragm is damaged and short-circuited, causing an explosion. In addition, the 18650 battery is 3c discharge, your electric scooter is 350w, the battery used is lower than the discharge current of your electric scooter, this will cause the lithium battery temperature to be too high, the current is too large and the life will be shortened. In the case of drum kit scrapping, if your electric scooter is very powerful and very fast, it is recommended to choose 18650 batteries with a current of 10c, so it is obviously very important to choose the right battery!


4. Do not "full charge" or "overcharge", do not need to "activate" the lithium battery


After buying the electric scooter lithium battery home, many users still follow the lead-acid battery method, charging the lithium battery for the first three times for 10-12 hours. They think that the lithium battery needs to be activated. In fact, this affects the life of the lithium battery very much. More strange people think that superstition trickle charging is to continue charging for another hour after the electric scooter is fully charged to offset the interference of internal resistance. These practices are all wrong. The correct approach should be to charge directly after fully charging. Unplug the power supply. Lithium batteries for electric scooters should not be charged overnight as they are prone to fire.


Five, do not need full power storage


Lithium batteries (18650 batteries) for electric scooters from industrial design companies are usually purchased at 2-3 grids. There are very few fully charged batteries. Long storage time at full charge will reduce the capacity of lithium batteries. In addition, also need to pay attention to is to choose a better quality protection board. Pay attention to these points, it is no problem for your electric scooter lithium battery to use for five or six years.
