I am new to PVs and Bloog. Been reading a learning a lot on this forum. Thanks everyone for almost 2 weeks without an analog! I have recently discussed how much I love the mini Bloog maxx fusion. However, I need some advice. I'm thinking about purchasing a 3rd battery and don't know whether to buy the 78mm or the 65mm or even the new trifecta. I would also like to know why so many on ECF are so adamant on going to bigger batts and mods. I don't understand this. To me right now the Bloog mini is plenty. It gives off plenty of vapor and taste. However, will I start to get an itch for something bigger along the way? Why do so many want to go bigger? Now, back to my original question. I like the mini size and it seems to hold a charge for most of a work day and about half a day on a none work day. How much longer will a 78 batt last and how long can I expect the trifecta to last? If I get the 78 batt than I will have to purchase a new charger with it since I ended up with a mini kit with no way to charge larger batteries. I really like the idea of the trifecta, but it does seem rather long. Help me to understand so I can make a better decision on purchasing these batteries.
