main function

c) Coulomb meter
Not only do coulomb meter accurately displays the capacity of battery charge with the way of real-time detection, it also can be shown by LED on a scale of 1 to 10 in red as well.
It typically adopts booting test mode, showing the 10th unit bar from the left if battery power is full, otherwise it will displays the scales of last power-off state, and then it will successively indicate the 9th and 8th etc. from the left along with the battery power going down.
