21700 Flat Top Battery

Make sure you get the batteries for your optics here. With the 21700 batteries I have bought them from two different places and neither fit my scope. These are the only batteries that fit that I have found.

Quick shipping and batteries seem to hold up good

Very good product, just what I needed for my DNT Optics TNC335R

The new larger battery works really well and as advertised I am experiencing the long up time availability to use the scope at night using all the features of thermal
and IR. Very well pleased with this set up.
