Batteries for a DIY dna 200 box mod

[Tim0th3e]

Hello,
I've a dna 200 box mod with dual batteries. What kind of batteries can I take? 2 batteries (3.7v) is 7.4v. But a lipo battery must be 11.1V. So is that compatible? 

Thank you very much
Timothée

The DNA200 can work in two different configurations.

• 200 watts max in a 3s configuration (11.1v)
• 133 watts max in a 2s configuration  (7.4v)

95% of the time I use Samsung 25R 18650s. They are inexpensive as far as the better batteries goes, rarely cloned, and can take 20v applied (at 5A) for 24 hours without blowing up.
