Explain the correct use of model aircraft lithium batteries

At present, I am very satisfied with the 130 yuan 1800mah12c. This is a brand I don’t know. If the receiver is turned off halfway (such as debugging), then bad luck will come. If the receiver is turned off halfway, assuming the voltage is 10v, then when it is turned on again, the adjusted maintenance voltage will drop to 10x65%u003d6.5v. This result is a very serious situation, the battery is discharged. Although the battery voltage can be distinguished even if it drops from the power source, it may not be able to fly, but it is still very dangerous and will discharge if you are not careful. Therefore, from the beginning of the flight, the battery cannot be powered off, or should be filled up for the flight again. Athos mentioned electricity in the book. As for charging and debugging, a throttle valve should be set to keep it safe. How to use lithium-ion batteries correctly? 1. Charging 1-1 Charging current: The charging current must not exceed the specified maximum charging current (generally 0.5~1.0c or less). Charging with a current higher than the recommended current may cause problems in the charge and discharge performance, mechanical performance, and safety performance of the battery, and may cause heat generation or leakage. Currently on the market use 5C rechargeable model aircraft batteries, it is recommended not to use 5C recharge frequently, so as not to affect the battery life. 1-2 Charging voltage: The charging voltage shall not exceed the specified limit voltage (4.2v/single battery), and the maximum charging voltage per cell is limited to 4.25v. (Direct charging is strictly prohibited, otherwise the battery may be overcharged. The user is responsible for the consequences of battery use due to the user's own reasons) 1-3 Charging temperature: The battery must be charged within the ambient temperature range specified in the product manual, otherwise the battery may be easily damaged. When the surface temperature of the battery is found to be abnormal (that is, the surface temperature of the battery exceeds 50°C), the charging should be stopped immediately. 1-4 Reverse charge: Correctly connect the positive and negative poles of the battery. Reverse charging is prohibited. If the positive and negative poles are connected in reverse, the battery cannot be charged. Reverse charging can cause damage to the battery, and even cause heat, leakage and fire. 2. Discharge 2-1 discharge current: The discharge current shall not exceed the maximum discharge current specified in the manual (incoming line). Excessive discharge will cause the capacity to drop sharply, causing the battery to overheat and expand. Discharge temperature: The battery must be discharged within the operating temperature range specified in the manual. When the surface temperature of the battery exceeds 70°C, the operation is suspended until the battery cools to room temperature. 2-3 Over-discharge: Over-discharge will cause damage to the battery. When a single battery is discharged, the voltage cannot be lower than 3.6v. 3. The storage battery should be stored in a cool environment for a long time (more than 3 months), the temperature is best to be 10-25℃, and there is no corrosive gas at low temperature. In the long-term storage process, the battery is charged and discharged every 3 months to keep the battery active and ensure that the voltage of each battery is within the range of 3.7~3.9v.
