I wouldn’t use ’em in practice, if only because contact would be spotty at best, only making contact through raised rough patches on the ring, and/or compressing the shrink-tubing ’til the ring hits metal.
I just did it to play with it, test it, check out the ramping, etc. Damn it’s a bright light…
Actually, I found no signs of compression on the shrink-wrap and ran them for a good while and all 4 were basically 3.4xV showing good contact. I wouldn’t hesitate to use them as long as you are aware of the bump-in-the-night thing.
BangGood is carrying the light. Current price is around $50 US.
Thorfire has posted the Q8 on their Amazon US store with a promo code that got mailed to me to bring the price down to $50 as well. I don’t want to to spoil that code so I wont post it, check with M4DM4X on his deal thread and web site for codes. If you can’t find it elsewhere, PM me.
The Button top Samsung 30Q are 3.6v and I was looking for a charger for these and came across the Nitecore i4 Intelligent Multi Battery Charger however it states 3.7v does this mean I can use the i4 to charge these Samsung batteries?
