The basic settings allow you to check a battery’s voltage, voltage balance across all cells, temperature, remaining power, total capacity and the number of times it has been charged.
With the cell voltage balance, all batteries should have no more than a 0.04v difference. If this is exceeded, there is an error with the battery which should be checked by an authorised repair centre.
You can also check and set the critically low battery warning between 10% and 15% and the low battery warning from 15% to 50%.
You can also enable and disable a drone’s RTH. The RTH feature checks the battery level available and will bring the aircraft back to its specified home point.
