Planning on building my own mod using a either the DNA 200 or DNA 250 board. Have been tossing around between Lipo battery and 26650's. was thinking of coming up with a design for 3 26650's set up im a similar style to the RX 200 line but just seems that it would way to clunky and huge. So have decided to check into the possibilities of dual 26650's and if it would even be a liable build, assuming i could get my hands on a decent set of 26650 batters. Ive only been using 18650's and still learning little things here and there, im never afraid to ask questions or receive criticisms, just please no outright jerk criticisms. Any good advice would be much appreciated.
