Thinking of dyi'ing a dna30 box mod. Ideally, I would like to have 2 18650's running it but not sure wether to put the batteries in series or parallel or if its even an option with the Dna30 chip. What are the pros and cons for each? Haven't made any purchases yet as I am currently trying to gather as much info as possible.
Cheers!
