Why do drones use lithium batteries?

Why do drones use lithium batteries? 1. Solve the problem of over-discharge and give birth to smart batteries such as laptops, drones, and electric vehicles. If the power supply is stopped immediately to prevent battery over-discharge, the computer will shut down immediately, and a lot of data will be too late to save; The sky will fall straight down; the electric car will break down without warning. Therefore, the discharge cut-off of the smart battery is only the last line of defense for battery self-protection. Before that, the management circuit must calculate the end-of-life time to provide users with early warning so that users have enough time to take corresponding safety measures. 2. Solving the problem of charging and storage has spawned smart batteries. Lithium batteries have become popular now. As we all know, there are special requirements for charging lithium batteries. At present, a large number of lithium battery packs adopt the form of multi-cell series and parallel. Due to the individual differences of the cells, it is impossible to achieve 100% balance between charging and discharging. Therefore, a complete set of charging management circuit is particularly necessary. And this is the second function that the smart lithium battery must have to complete the charge management and discharge management of the lithium battery pack. 3. Solve the problem of electrical corrosion and aging of the electrode contacts and give birth to smart batteries. When we connect the battery to the drone, sparks are emitted from the plug and accompanied by the sound of ignition. Over time, the connection reliability of the plug will be reduced, which will cause the plug to heat up and even melt in the air. It is not uncommon for drones to crash due to aging plugs. In order to solve this problem, the lithium battery intelligent management circuit has to be used again.
