How much voltage is good for UAV battery?
Release time: 2022-09-29
With the increasing application of UAVs, UAV manufacturers will design the corresponding UAV battery voltage and specifications according to the product use and market positioning. As a senior battery manufacturer for UAVs, Shibao has developed a multi voltage platform product line with different battery cells according to customer needs. ① 3.7V cell normal pressure version: 11.1V, 14.8V, 22.2V, 44.4V, etc.; ② 3.8V cell high voltage version: 11.4V, 15.2V, 22.8V, 45.6V, etc, ③ 3.85V high voltage version: 23.1V, 46.2V, etc. Therefore, as long as the voltage and power of the UAV motor match the voltage and discharge characteristics of the lithium battery, it can be considered appropriate.
1. How is the voltage of UAV battery and battery cell calculated?
Take the nominal 3.7V flexible polymer lithium battery cell commonly used in UAV batteries as an example. Just pack the lithium battery cell in series, that is, AsBp marked on the battery package, A is the number of series connections. The 14.8V UAV battery requires four 3.7V battery cells in series connection.
2. UAV smart battery can implement battery protection strategy by measuring voltage
The cell voltage will continuously decrease from 4.2V when fully charged to 3.3V when used. When the battery deviates significantly from the nominal voltage for a long time, the battery life will be accelerated. However, the battery of intelligent UAV will be equipped with bms. Take various measures to reduce the self loss, self heating, and alarm light of the battery, so that each cell in the battery can be as close to 3.7V as possible, so as to protect the battery and extend the battery life.
How long is the general service life of motorcycle battery
The battery life is generally 300 times of full charge and discharge. The battery is a kind of consumable, and its price is high. Therefore, it is necessary to use and maintain the battery correctly and extend its service life to make the best use of everything.Learn more
