Tips for Battery: 

• The formula for capacity and battery using time.
• For example: Voltage: 11.1V; Capacity: 5200mAh/58Wh 
• The capacity = 58Wh / Voltage * 1000
• Battery using time = Charge Remaining / Dischage Rate(Amperage) 
• For example: Charge Remaining(mAh): 6960; Amperage(mA):-2898 
• The battery using time = 6960 / 2898 = 2.4 hours.
