There are two possibilities:
1.
2. Overdischarge.
Even if the battery overcharges, it will not stop charging all at once. Recharge it. After about 10 minutes, touch the charger to see if it is hot. been loaded. If it's not hot, it's been charged. This means the connector is not making good contact, meaning there is no charging at all.
The battery has been left too long. Lithium-ion batteries for model airplanes are much trickier than you might think, otherwise the cost of flying with an oil engine is about the same as flying with a gas engine. oil. an electric motor of the same level, it is because the battery is worn out due to lack of battery maintenance. The battery may be stored at the dealer for up to one month after leaving the factory. If the dealer does not maintain it, the battery will die.
Notes: Firstly, the battery hasLithium model aircraft cannot be stored fully charged or empty. Second, it must be loaded and unloaded in less than a month;
Original poster, the Grignard ACE battery is considered a mid-price battery, with a theoretical usage life of 300 times.
First of all, when using lithium batteries, you need to configure a suitable ESC. The selection is based on the discharge speed c indicated on the lithium battery and the battery capacity mah. The calculation is 1c multiplied by 1000mah. the maximum continuous discharge current of the battery 1a. Excessive discharge speed will cause the lithium battery to swell and its service life will be directly reduced by 30%.
Second, lithium batteries cannot use all of their energy when in use. They should be stopped if there is still 20% left in the battery. Excessive use will reduce thebattery life of more than 10 times.
Third, lithium batteries should be placed in a cool and dry place at 25 degrees Celsius when not in use. The battery should not be stored fully charged, nor should it be stored empty after use. be maintained at approximately 80%. And load and unload once a week. If the battery is stored empty, the battery will be directly destroyed.
If used correctly, lithium batteries can be used 300 to 400 times.
Thank you.
Correct the guy on the third floor, turbojets use aviation kerosene, not gasoline. The smallest oil-fired turbojets have a static thrust of 4 kg, and the smallest are ducted electric machines, therefore the electric ones. are actually more efficient, but have low endurance. In addition, gasoline models account for a small proportion in China, and most of them are mmethanol models.
