The following points of 4s drone battery
application must be paid attention to, right methods of application are the best way to extend battery lifetime.
1.Uncharged storage. Battery with full electricity can not be stored over three days, if electricity isn’t be left out, some batteries will swell directly, some batteries may not swell for the moment, but after several times full of electricity, they will scrap directly. Therefore, the right way is charging after receiving flight mission, if there is no mission in three days, please charge single voltage to 3.80-3.90V and store. If flight mission can’t be carried out because of some reasons after charging, please charge single voltage to 3.80-3.90V and store after three days. If the battery isn’t be used in three months, please charge it and left it out once and keep storing, it can extend its lifetime. Battery should be stored in a coll environment, it it need to be stored for a long time, it is best to put it in sealing bag or in sealing blast box, its temperature had better be 10-25℃ with dry and non-corrsiveness gases.
2.No damage to outer skin. The outer skin of battery is the important structure for preventing 4s drone battery
explosion and leakage fire, the damage from aluminum plastic of polymer will cause fire and explosion directly. Battery should be taken and put gently, fastening ribbon tightly when in a plane, because battery outer skin may be broken because of loose ribbon when it is in large dynamic flight or crash-land.
3.No short circuit. This is always taking place in the maintenance and transport process of battery welding line. Short circuit will cause fire or explosion. When it is found that battery need welding line again when it is broken after using for a long time, especially electric soldering iron should be focused on , do not touch the positive pole and negative pole at the same time. Besides, in the process of battery transport, the best way is to put every drone battery
in blast box with sealing bags in order to preventing the positive pole and negative pole will touch other substance because of crash in the delivery process, it will cause short circuit because of broken skin. Look at the picture four, it is broken because of short circuit.
4.Don’t catch a cold. This point always be ignored by many people. There is always low-temperature weather in north and high altitude areas, if battery is stored outside for a long time, its electricity will decrease quickly, if it is used for normal flight time with normal temperature, there must be some problems, at this time, rise alarm voltage ( for example, switch single alarm voltage to 3.8V), because voltage drop is fast in low temperature environment, land at once when alarm rings. At the same time, treat battery with heat preservation. Before flight, battery should be stored in warm environment, such as houses, cars or blast box. Install battery fast before taking off and flying a mission. Cut down flight time with low temperature to a half with normal temperature to keep safe.
