Unfortunately he didn't read all that much on the first site he links to (BatteryUniversity (http://batteryuniversity.com/)), so he didn't get it right.

Here's a good example that something went over his head...

Quote

For example a RC LiPo battery that is rated at 1000 mAh would be completely discharged in one hour with a 1000 milliamp load placed on it. If this same battery had a 500 milliamp load placed on it, it would take 2 hours to drain down. If the load was increased to around 15,000 milliamps (15 amps) a very common current drain in a 400 sized RC helicopter while hovering, the time to drain the battery would be only about 4 minutes.
