What type of battery is in the RC?
Is it LiPo? Or is it a type the can be stored fully charged?
Any special considerations?

Hi. Thank you for the inquiry. The intelligent battery of the DJI Spark is LiPo 3S. You can store the DJI Sparks battery fully charge because the intelligent battery of the Drone is capable of discharging itself when stored for a certain period of time.

I am asking about the RC, NOT the Spark.

I am inclined to agree. I also notice if his reply fails to help you never hear from him again.

Ditto...his most often reply is what mobile device you're using...even if the question has nothing to do with it.

Which then raises the question....How do you get a meaningful, accurate  answer to your question.

If I have not gotten a definitive answer to my question in the next 24 hours I will re-post it with different wording and no room for mis-interpretation and see if that will lead to better knowledge.

Let's see
You use OTG, RC charges the phone
You use OTG upsidedown, Phone charges the RC
Every phone charger charges the RC
Every powerbank does so, too

I think it is a LiPo
In these days anyway.

And for storage:
I "refill" when down to 2 LEDs
If i wanna fly in the next days.
But store it after a flightday without recharging, anyway.
My personal observation is that flying ~15 batteries is possible.
And still have one LED steady.

I know it is off topic, but lately I am also under the impression that some admins either do not understand or are automated.

most of the DJI admin accounts are shared at the factory in china
