It's been a while since I did a really big battery bulk deal. It was about time for me to start retiring some of my older batteries and wanted a bulk deal shipped from the USA. Here we have a solid battery that ships from the USA for free. Your going to get 12 for $48.59 which comes down to just above $4.00 a battery which is a steal (with the free shipping).
This vendor also sells smaller lots of various different brands but this is the best deal I could find. These will work great with mods and 18650 flashlights.
