How to properly use and maintain model aircraft batteries?

1. Use a dedicated charger. This charger can be a lithium ion or lithium polymer charger. The two are very close (output voltage 4.1~4.2), which will not damage the battery. 2. Not overcharged. There are requirements for chargers. Some chargers have imperfect power-off function after being fully charged, which causes the single-chip battery to be fully charged to 4.2V and has not stopped charging. In addition, after some chargers have been used for a period of time, it is easy to aging due to the aging of the components. There are problems full of non-stopping problems. In addition, remind everyone that when charging, be sure to charge the battery according to the specified charging C number or a lower C number, and not exceed the specified charging current. 3. Pay attention to the charging temperature. The charging temperature of the aeromodelling battery should be kept at 0℃-45℃, because the temperature of the charging environment is too high, which will cause the temperature of the battery to rise, so when the battery surface temperature is found to be abnormal, the charging should be terminated immediately. 4. Do not overdraw the battery power of the aircraft model. The discharge curve of the battery shows that at the beginning of the discharge, the voltage drops relatively quickly, but when the battery is discharged to between 3.9V and 3.7V, the voltage drops not fast. But once it drops to 3.7V, the voltage drop will speed up. Poor control will lead to over-discharge, which can damage the battery in the slightest, and cause a bomber if the voltage is too low. 5. Do not force the flight if the temperature is too high or too low. To preheat and keep warm, this principle is ignored by many flying friends. In addition, the battery needs to be kept warm. Before taking off, the battery should be stored in a warm environment, such as in the house, in the car, in the incubator, etc. 6. Quickly install the battery when taking off and perform the flight mission. When flying at low temperatures, try to shorten the time to half of the normal temperature to ensure safe flight. 7. Before installing or unplugging the battery from the aircraft, please keep the battery power off. Do not remove or insert the battery when the battery power is on, otherwise the power interface may be damaged. 8. If there is dirt on the battery interface, wipe it with a thousand cloth. Otherwise it will cause poor contact, causing energy loss or failure to charge. 9. Pierce the battery. If the battery is swollen, there is a safety hazard of fire. Especially when you are charging, you should stop charging immediately and move the battery to a safe place. 10. Don't hit the battery. The impact will damage your lithium polymer battery. It is possible that the battery looks good but has a short circuit inside. If the battery is hit, please carefully remove the battery from the airplane and move it to a safe place, observe it carefully, and let it stand for 20 minutes. 12. Do not place the battery near an open flame or a place with a heating source; 13. Do not store the battery in a humid environment or a place exposed to direct sunlight; 14. Please ensure that the battery is stored in a dry and normal temperature environment (the ambient temperature is 10 -30 degrees is best); 15. Please ensure that there are no flammable and explosive objects around the battery storage; 16. Please ensure that there is no squeezing phenomenon during battery storage and transportation, and ensure that the battery is not squeezed by any external force; 17. Do not use for a long time Please charge about 50% of the battery to store the battery (single cell voltage is between 3.8V-3.9V); 18. Please check the battery storage environment frequently. It is best to charge and discharge the battery every 2-3 months , In order to maintain the stability of the drone battery.
