High Discharge platform, more powerful, long endurance time, increase the working efficiency.
Almost all Lithium Polymer batteries you buy today will come with a ‘C’ rating. The ‘C’ in C rating stands for Capacity. The C rating is the maximum, safe, continuous discharge rate of a pack as specified by the manufacturer, so when you see 20C printed on your label, it means it can be discharged at 20 times the pack’s capacity, ‘continuously’. Capacity is usually measured in mAh and a popular cell size is 2200mAh. Therefore, so by way of example:
2200mAh 20C Cell = 2.2A x 20 = 44A continuous discharge
Along with the continuous discharge rate, some batteries display ‘burst’ discharge rate. This is typically twice the continuous discharge rate. It usually means the battery is capable of allowing twice the current, but only for a few seconds at a time.
Now more and more people are starting to use high-voltage drone batteries. Why do plant protection drones use high-voltage batteries? Why is its battery life better? With these questions, let’s analyze it together:
1. Energy density
The high-voltage battery has a higher energy density. Now compare with 12S 16000MAH 25C battery:
Energy density of high voltage battery: 3.8V*12S*16AH/4KG=182.4WH/KG
Energy density of ordinary battery: 3.7V*12S*16AH/4KG=177.6WH/KG
2. Discharge platform
High-voltage drone battery discharge platform is higher.
The median voltage of the discharge of the high-voltage battery 1C is 3.8V, while the median voltage of the discharge of the ordinary battery 1C is 3.7V, which is lower than the voltage value of the high-voltage battery.
3. high current measurement
High-current discharge, the voltage of the high-voltage drone battery drops more slowly.
Single-chip battery discharge actual measurement: After they are fully charged and connected to the same 160A load, test their instantaneous dynamic voltage value.The high-voltage battery 3.8V 16000MAH 20C has a full-charge voltage of 4.35V. After a 160A load is connected, the instantaneous dynamic voltage is 4.02V; Ordinary battery 3.7V 16000MAH 20C has a full charge voltage of 4.35V. After a 160A load is connected, the instantaneous dynamic voltage is only 3.75V.
4. Released capacity
Under the same load and alarm voltage, the high-voltage drone battery discharges more capacity, while most of the ordinary batteries are not discharged. It is also used for the 10KG plant protection drone test. The batteries are 12S 25C 16000MAH, and the same alarm voltage is 3.7V, which is 22.2V or 44.4V. The output capacity of the high-voltage battery is 9280MAH, while the output capacity is only 75200mah.
From the above data, we can see why the battery life of high-voltage drones is stronger.
