It looks drunk lol
Lovely little box-o-light !
It reminds me of a cheap version of this that I made like ten years ago… I gotta find a picture somewhere
Ok, the 200mAh cell is rated for 20C continuous so about 4A output.
First i hooked it up to a red XP-E with 22AWG wires, replacing the stock wires which are very thin.
The reading shot up to over 5A for a second before the LED popped.
Then i used it to power a Nanjg 105c supplying an XM-L emitter, it did so quite happily giving 3A then steadily dropping after 60s or so as expected with such a small cell.
Finally after charging again i connected it direct drive to an XM-L on a copper MCPCB on an aluminium heatsink, it gave a steady 4A, again gradually dropping in current and the lipo warming up slowly over the course of a minute.
