Maybe you can regard me as a mech mod with regular protection. Normally I work with dual battery in parallel, but I can also work with only one battery!
I performance like a mech mod, Battery voltage full power output - simple, straight, powerful and no delay. And I also have regular box mod's protection:
short-circuit protection, battery "+" and "-" install protection and etc.
My body is made of aluminium anodizing and top bottom caps are gun metal. My net weight is less than 100grams. Total weight with DPRO RDA is only 130grams. I'm a very light and small guy. my 3D size is 84.5mm x 44mm x 28mm. You'll feel my comfortable and soft body when you hold on hand.
