Yeah, I'd stick with the tried and true "known good" 20A+ continuous
batteries the sub-ohming/mech crowd like to use (Sony VTC4/VTC5, LG HE2/HE4, Samsung 25R, etc).
Not only for safety, but for future headroom. The price difference between a good 20A continuous vs a 10A continuous is marginal, but the ability to use that 20A battery in a higher wattage
device later is worth having. Nothing worse than having a stack of good
batteries that you can't use later as you upgrade because you tried to save a few pennies now and got the bare minimum.
