its called an X3S these days - mine is several years old and has been mod'ed to 150 /325 (low/high) lumens
it will run about 10 min on "high" IIRC - it never gets too hot to hold as the output starts...
I looked up the rating of a "typical" 10280 - capacity is 200 mAH (milli Amp Hours).
a good charging rate (.5C) is about 1/2 that of that - or 100mA as you said.
the lowest charger i have is 680mA - so not a good choice.
hmm 10280's - I didn't know these existed - When I suggested google, I was actually thinking 10180s - which have several domestic sources.
the only thing i found on 10280s was
https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20190407045039&SearchText=10280+ with 60 day shipping...
I assume you mean the DX80
there are several posts on the DX80 both here and on the "other' forum.
I spent a LOT of time and some money ($30 to RMA it back to china) - with no response
YMMV - but I would write it off and save your sanity; I will never purchase Imalent again.
