I (think) you made a good decision going with the g6 batteries from Halo. although I usually recommend the Volt or Bloog batteries, because I know for a fact they stay around 3.7 volts, the halo g6 batteries are also known to hoover around 3.7v for their entire charge. The g6 batteries are good batteries from what i am hearing and the halo kit was priced well. I hope you picked up an extra (3rd or even 4th) battery because the small cig-alike batteries are known to die pretty early in life when compared to larger batteries. 6mo to 1yr as opposed to the 1yr+ that we get with the larger eGo style devices. the ECF unofficial motto is ALWAYs keep backups, for your backups. that means that you need your initial 2 batteries, but then you need a backup battery, but you also need a backup battery for that backup battery. lol. If you choose to not follow the motto, your gonna end up having a bad time at some point. Because you chose to go with cigalikes, basically 2 of those batteries should be considered one PV. So in my humble opinion and advice, you should get 3 sets if you want to completely stay out of trouble. They do die, but more often than them dying for good, the charge dies! Those batteries are tiny and they become fully discharged very quickly. So u will want to have a lot on hand incase 1 of them dies. A remedy for this is a PCC. A PCC is a personal charging case. U can carry a PCC in your pocket. It will charge 1 of ur G6 batteries while it is in your pocket. This will save you and pay for itself over and over again. If I was mainly relying on the cigalike batteries, i would definitely have at least 6 batteries, at least 1 PCC, and at least 2 AC wall outlet chargers to charge 2 of the batteries once your home from work, or to charge one while your PCC is charging. This backups for backups goes for juice as well. I'm not sure how much juice you picked up, but vapers usually vape 3 to 6ml of juice each day. I sometimes vape 6+ ml of juice. If you bought just one pack of cartomizers, those cartos only have 1.5 to 2ml of juice in each of them. So keep that in mind. Your going to need to stock up on some large refill bottles of juice once you think of some flavors that yOU KNow you will enjoy. simple flavors are usually good for all day vapes. things like vanilla, grape, caramel, etc. And the cartos... 5 cartos is a sentence to hell if that is all your going to rely on for a while. a burnt cartomizer never comes back to life IMO. and they can and do burn by accident every now and then. A carto, for me, in my opinion, only lasts around a week. maybe arouuund 2 weeks if your lucky. Other than this all, you chose good batteries. Time to stock up on more batteries, more chargers, more juice, nd more cartos! u may also want to look into nano clearomizers and shorty cartos for some variety. There are cartomizer tanks too. Do some research on those. enjoy your vape journey buddy!
