Lithium batteries have absolutely no charging requirements. Just use the original charger and charge it every day.
There is no need to deliberately force the charging time for the first time or the charging duration. Everytime. Yes. Just be careful in a few places.
1. Charging time should not exceed 12 hours at a time and insist on charging every day. Charging data is based on a full charge. and unload. But if it is really fully charged and discharged, it will also damage the battery, so just charge it every day and try not to use all the energy at once.
2. Charging environment, it is best not to charge outdoors, in very hot or cold places.
3. Charging frequency, once a day is preferable.
4. When using, do not try. to open several applications at once, becausethe battery will be too discharged. Nowadays, mobile phones have many functions. When the feature is enabled, it will consume a lot of resources, resulting in increased power consumption. it is too discharged, you need to check the battery temperature. If the battery starts to heat up, it means there are too many apps open. If it takes a long time, you can rest for a while before using it.
Finally, never use batteries from another brand, try to use original or well-known brand batteries, otherwise they will be dangerous and could explode.
According to the information You provided information, Tianneng 48V 24A lithium battery, using a multimeter to measure the voltage of 53. , so it may not be completely consistent with the actual voltage.
Remaining battery power: The remaining battery power will affect the voltagen battery output, so it may not be completely consistent with the actual voltage. The lower the remaining battery power, the lower the output voltage.
Battery Aging: Battery aging will also affect the battery output voltage. If the battery has been used for a period of time, its life may have been reduced and the output voltage will decrease accordingly.
Therefore, whether the voltage you measured is normal should be judged according to the actual situation. Generally speaking, the battery output voltage should be relatively stable. If there is an obvious gap, you may need to consider replacing the battery.
