Craft ideas of lithium battery design.best batteries for solar power storage

　　1. Whether it is used in the battery in that aspect, the safety of it is the safety of it to ensure the safety of the battery during the use and storage of the battery.

　　High fever burns, get upFire burns are more dangerous!

　　2. The capacity (power) can support the time requirements of the electrical equipment for one time.

　　3. Platform requirements

　　Lithium battery discharge at one time for a certain voltage value. For example: After the mobile phone battery is discharged to 3.6V, it is automatically shut down, and the longer the time of our battery 3.6V voltage platform is required. Follow this requirement according to the characteristics of the material.

　　4. Use environment

　　In different use environments, the performance of the performance has a great impact, and there is a great gap between the capacity of 70 ° C and low-temperature -20 ° C. So select the required materials according to the use environment (the electrolyte, etc. of the positive pole material)

　　5. Peak and continuous current during work

　　In different working hours, the output current is different, so the materials must be selected according to different current values, such as: the battery with a large discharge current, when we design, we must consider the density of the surface and the type of electrolyte. The number of pole ears, the number of point welding joints, the type of extreme ear, the overcurrent of the lead, and so on.

　　How long can drone batteries use

　　In fact, there are many factors that the drone battery can be used. For example, how you use the battery, such as the quality of the battery itself, it will affect the use time of the drone battery. The background of the estimated time here is that the battery is slightly stable and the battery use time is universal on the market.

　　Below 5000mAh

　　In the range of 5000mAh, unmanned batteries are generally more suitable for entertainment drones. The estimated time is 10 ~ 20 minutes. In other words, the minimum use time of drone batteries is about 10 minutes. The drone battery supported by the Mavic MINI in DJI last year is 2400mAh, and the length of the labeled is 26 ~ 30 minutes. The actual use of Royal MINI is almost this range.

　　5000mAh ~ 8000mAh

　　The 5000mAh ~ 8000mAh battery is generally used in FPV more, especially the competition level. The use of drones in this range is generally 21-30 minutes. It also depends on the actual situation, such as whether the drone is a high -power battery, whether there is a phenomenon of violent discharge, and so on. But the basic duration can stabilize in this range.
