Wisemec Reuleaux DNA 200
The Reuleaux by Jaybo Designs is the only triple-18650 mod DNA 200 currently on the market. The awesome DNA200 chip set is a cutting-edge platform, and batteries have mostly been limited to low-mAh LiPo packs. This epic device draws power from 3 18650 batteries in series.
With so much power at your fingertips, it is no surprise that the Reuleaux has built-in safety features like reverse polarity protection, which is a first in the industry.
