Features of UAV lithium batteries
UAV lithium batteries are high-rate lithium batteries. Compared with other batteries, they require a higher discharge platform and need to consider the battery weight. Therefore, the battery capacity, discharge rate and voltage of the drone battery need to be designed according to the aircraft load and flight time.
Features of lithium batteries
1. It has a higher weight-to-energy ratio and volume-to-energy ratio.
2. High voltage. The voltage of a single lithium battery is 3.6V, which is equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries.
3. Low self-discharge and long-term storage are the most prominent advantages of this battery.
4. No memory effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so lithium batteries do not need to be discharged before charging.
5. Long life. Under normal working conditions, the number of lithium battery charge/discharge cycles is far greater than 500 times.
6. Fast charging. Lithium batteries can usually be charged with a current of 0.5 to 1 times the capacity, shortening the charging time to 1 to 2 hours.
7. Can be used in parallel at will.
8. Since the battery does not contain heavy metal elements such as cadmium, lead, and mercury, it does not pollute the environment and is the most advanced green battery in contemporary times.
9. High cost. Compared with other rechargeable batteries, lithium batteries are more expensive.
