Deep Discharge Circuit for DJI 'Intelligent' Batteries

This is my improvised automatic 'Intelligent Battery' deep discharge circuit. This is for the DJI Phantom 2 & Phantom 3 series quadcopters...
As we all know, every 20 or so cycles, we are supposed to drain the batteries to less than 8% capacity. This is for the calibration purposes of the Intelligent Battery.
When the batteries have been drained low enough - the Intelligent Flight Battery will automatically cut power output before the battery reaches the permanent damage zone of the LiPo.

How many cycle do u hav in your battery??? And how much % battery life do u have?

Do you need to charge the battery right after deep discharge or not?

[@modex20]

could you have used a couple of resistors instead of bulbs?
