Your post didn't say my answer to the post was wrong, you said vendors shouldn't be allowed to suggest batteries and implied that I was trying to mislead, so I was responding to that - look at what I quoted from you. If you had simply said my answer to the post was wrong then that's totally different - I wouldn't feel the need to defend my posting from that, that's the whole reason this is a discussion board so people can discuss it.
All I can do is answer the question that's being asked. The OP said that even though it's a "180W" mod he knows that in actuality it tops out at 120W (the mod does at max setting, not him setting it lower than max). For that set of circumstances, the 25R is my suggestion and even the HG2 might be better depending on how high you set it. If the information he posted on the mod is wrong and it does go much higher than 120W or there's question about that, then you're totally right and the VTC4 or one of the other 30A batteries like VTC3 or LG HB2 should probably be used.
