The best batteries I have found available in 350 size are the authentic AW branded 800mAh (new). The only place I know for sure you can get real ones is RTDVapor. Those are supposed to be the 10 amp batteries, although I have never seen an independent test. Tensai is supposed to be making honest 14 amp batteries in 350 size, but I have never seen one and AFAIK they are not available in the US. You will find some solid cell test data (in 650 size) on
@Mooch 's blog; and several beginner-to-advanced pieces and tutorials about batteries and safety in general on
@Baditude 's blog. Yes, Ohm's law is hugely important in mech modding. It is, in fact, your only safety factor to keep your batteries from overheating, or venting toxic gasses, or lighting on fire, or exploding in your hand. Do yourself a favor and learn about this before you get into trouble. You may wish to buy an iStick 30 to use while you do. Seriously. Failing that, don't buld that KFL below .8 using the authentic AWs I have mentioned, or below 1.2 with any other battery. Also seriously. I do not believe you're going to find an "all day" 18350, unless you only take a puff or two every hour. I never have. This advice comes from a guy who uses an MMV Nanos in 350 trim as his daily driver, and used a Nemi before the Nanos showed up.
