Alrighty, I have been doing a bit of research and it seems that as far as bang for buck, the sony VTC series is the way to go. I know that the VTC3 has a 30amp continuous draw, and that the VTC 4 advertises the same but has not actually been tested and that the 5 is tested and I believe it pulls at 35 continuous. Which is best for sub ohming? It seems that the safest you can go on the 3 and 4 is .2 ohms. Any experience? Thoughts? Inputs? I am just starting to chase that cloud and I am trying to do my research so that I can know what to go in on so that I am not wasting a bunch of cash with trial and error. Let me know your thoughts. If there are other batteries that you think would do better, feel free to throw it in as well.
