Wow using only 2 GA cells
It kicked in LVP
So I started stopwatch
After about 1 minute 25 sec it stepped down again
1m20s again
~52m again
~7m
~3
~33
~1h,32m
Still too bright to look directly into the LEDs.
And when waking it still worked. At ~12 hours now, after the cells have reached LVP on two cells.
This is awesome for the first 2,5-3,5 hours it was giving so much light I use normal lights at that brightness.
The ceiling bounce app crashes but will try to get it running for I would love to see a graph on the runtimes. Starting on turbo with 1 minute stepdown for then it won’t get too hot
LVP should not be kicking in after only a minute of use. Even with only 2 cells it should last quite a bit longer then that if they were fully charged when you turned it on.
I have run my 10K lumen SRK’s with a single cell before and it didn’t step down in the few minutes I plaid with it (was trying to see how hot it got with only one cell).
Yeah, that doesn’t make sense:
Two GA:s (fully charged) should (easily) be able to deliver 20A without too much voltage drop, even 30A for a while (until they get too hot).
