UAV battery repair and repair problem analysis

At present, most of the batteries used by drones on the market are lithium polymer batteries, and the battery has over-discharge. If the battery is left unused for a long time and the remaining power is too low, the protection circuit will be activated and cannot be recharged. So, what will I do when I can’t charge, let’s first explain the problem of repairing drone battery over discharge. The general opinion on the Internet is that because the battery has been damaged, repairing is impossible and very dangerous. However, there are many ways to repair batteries on the Internet. So are there any reliable ones? As a curious researcher, I decided to try it myself. Since the lithium battery is strictly protected by the protection circuit, it should be closed before it becomes a real over-discharged state. Although the battery may be repairable, are there too many people who choose to give up? In other words, even if it cannot be charged, it is assumed that the protection circuit does not prevent charging, but there are many actual over-discharge conditions. This means that it is a false over-discharge state, and the battery's internals may not have changed. Therefore, I have repeatedly pointed out. We do not use any special tools. Repeat until charging is forcibly stopped. Or just a little trick, just start charging for a while, immediately close the charger, and try to remove the battery. What I have to do is not only simply charge the battery, but also give the battery a slight electric shock. This is a way to test whether the protection circuit can be protected. Moreover, since the charging circuit works for a short time, it is possible to charge it little by little. Will the charging circuit stop after repeating 10 or more times? However, the battery level remained at 0% and continued for more than an hour. Even so, when I observed it, it eventually reached 1%. I hope I can see it. However, this is dangerous and takes time, but the battery level gradually rises. When I was about 30%, I tried to unplug the charger. If it’s okay, I charge it 100%. This should be successful. Since the remaining battery power has reached 100%, I will use this battery to measure it. The first battery is a large-capacity type. I tried to detect it when the drone took off. Because the original battery is as good as the new battery, I can reach the target time without anything. Although there seems to be very little space, I am done. When I tried to charge, the remaining capacity became 100%. It seems to be resurrected like a brand new battery. Although it is a battery with a long storage time, it has been proved that lithium batteries have long-term performance maintenance capabilities.
