Drone Battery Information

• Battery packs used in drones consist of multiple lithium-polymer (LiPo) cells.

• Each cell has a capacity measured in milliamp hours (mAh).
• All cells in a pack have the same capacity.

• Full Charge: 4.2 volts per cell
• Nominal: 3.7 volts per cell
• Discharged: 3.5 volts per cell
  • Discharging a LiPo battery past this level will result in permanent damage.

The C rating found in the name of the pack (see below) refers to the maximum discharge rating. Multiply this number by the pack capacity for max current draw.

• Max current draw for a 5000mAh 40C pack: 200Amps (5000mAh * 40C)

• Example Battery: Turnigy 5000mAh 4S 40C Lipo Pack
