How do I discharge the Transmitter. Do I just use the cord I connect my phone with for this. Already did the battery packs using the cord for my ipads and iphone by connecting to the multi charger.

This map is for the aircraft battery, not the transmitter battery.I advise you to do some tests, taking note of controller status leds before / after flight, and before / after a fixed charging time. This is the meaning of leds extracted from manual:
STATUS LEDS
0%-13% blink, off, off, off
13%-25% on, off, off, off
25%-38% on, blink, off, off
38%- 50% on, on, off, off
50%-63% on, on, blink, off
63%-75% on, on on, off
75%-88% on, on, on, blink
88%-100% on, on, on, on
Once you get that data, I suggest you after a flight sesion recharging your controller only to 50% of their capacity, that's very close to optimal storage voltage.
All the best

Interested.... What is your reason for discharging the controller?How do I discharge the Transmitter. Do I just use the cord I connect my phone with for this. Already did the battery packs using the cord for my ipads and iphone by connecting to the multi charger.
Maybe not as different as you might have assumed- LiPO (Lithium Polymer) is a type of LiION cell. Most of the storage/usage recommendations have universal application.The following was part of another thread re MM batteries...
Thanks to Mavic South Oz, I was directed to a site that provided some great information re the MM lithium ion batteries and I thought it might be worth sharing. The following is a quote from batteryuniversity.com...
BU-702: How to Store Batteries – Battery University
“Similar to a mechanical device that wears out faster with heavy use, the depth of discharge (DoD) determines the cycle count of the battery. The smaller the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life. The exception may be a periodic calibration of the fuel gauge on a smart battery or intelligent device.“‘
In other words, our batteries for the MM are different than those in the larger DJI drones and in that regard, we have some advantages. First of all, there’s no memory so we can charge them at any point of discharge. Also, we can keep them fully charged and ready for action without shortening their life.
It appears to be two conflicting opinions now if you read the last paragraph of the Battery University piece. How does an average guy know which one to go by??? I’m confused, do we keep them fully charged or not? ??????Maybe not as different as you might have assumed- LiPO (Lithium Polymer) is a type of LiION cell.

Thanks for the quick response. So is it okay to keep them fully charged?Conflicting opinions?
The “lithium based” commentary in the link you posted has equal applicability to LiION and LiPO. LiPO is LiION chemistry.
Preferable not to. Of significantly less consequence when used in less demanding applications, powering the remote controller for example.Thanks for the quick response. So is it okay to keep them fully charged?
