Gchart, first of all, congratulations on your family's new addition!
I was thinking about holding off on buying this light but then there was that blessed Vipon discount code. Anyway, somehow, I got the code and wham!, I've got a new addition, too .
When I got it, my question was how fast (rate & time) does it charge the battery in light(?). With the Sofirn stock batt., this is what I found:
Charge rate along with other parameters,

And, ultimately, the results,

I first discharged the battery with an Opus I keep at work so started this charge cycle in the evening. 0.9A isn't too slow but I'm a bit miffed at this taking 5 hours. I guess I'm used to charging with the MiBoxer at the house. If anyone here is familiar with these 'cable testers' you might shed some light about the charge time. Like the OP review findings, the end voltage was around 4.17V.
I've read some fairly negative comments where Sofirn could have added UI features like the SP32A and/or SC31 and I'd like those too. SOFIRN, SEND ME THE VERSION 2 FOR A REVIEW!
But I'm happy with the beam pattern, tint and definitely the 18350 tube. The beam angle is so wide, it's like a mule with a hop spot!
The Sofirn 3000 mAh is curretly in the MiBoxer to compare results between charge options. More to share...
