Hello, everyone. I'm looking to find the best battery I can actually get (Which I can't find Sony's anywhere or I wouldn't be posting this) that will be safe for me to use with as low as a .35-.4 ohm build. I have a good understanding of ohms law, I'm looking to upgrade from my regulated mod and aspire tank to a tugboat atomizer and a 18650 shotgun mechanical mod, and I just can't find anything that has a strong amp limit and maH for all-day consistent vaping. I've been looking at the Orbtronic PD2900 batteries, yet I've been seeing very inconsistent opinions from everyone on the forums about them so far. Anyway, I was wondering if anyone had any input to help me find a better, acquirable battery for sub-ohming.
