I'm thinking it's more a labeling difference between manufacturers, or more specifically the length distinction between an unprotected and a protected cell?What's the difference between 17650 & 17670? Capacity?
Hey guys I just got my new dual output fury is it fine to use the rechargeable K2 I got from them I also got normal surefire batteries but was wanting to use the K2s around the house thanks Jonathan
I tried a couple rechargeable lifepo4 batteries in my 350 lumen light and they were only discharging 0.5 amps. On primaries the current was over 1 amp. These batteries are limited I assume
