Thoughts on Big Blue Black Molly 3?

I am looking to get one of these for those few times when I might want to shoot a short video clip (90-95% of the time will be still photography). The price seems reasonable for the lumen output. Does anybody have one and what are your thoughts? I can't seem to find any reputable high-capacity 26650 batteries which is a bit of a concern. Are the cheap ones off Amazon ok?

That looks like very good value for a combined video and focus light. 2600 Lm is plenty for macro and relatively closeup work, and the red LEDs and low output setting make it perfect as a focus light. I have several Big Blue lights (though not this one) and find them very well made and fairly priced.
