Your 510 regular is probably around 170-180 mah or so. If you are vaping it heavy, yeah that can be normal. You can get 510 mega batteries that should be 280 mah and you will notice a nice difference in battery life. Ego is of course a very nice option but since you just got your 510 kit and new to vaping a better option may be to get a PCC (personal charging case) $25-$35 or so. You charge it each night then the pcc can recharge one battery while you vape the other. The pcc should be able to charge 4-5 regular batteries before needing a recharge itself. Small enough to fit in your jacket pocket. Mega batteries will not fit a normal pcc however they do make pcc's for mega batteries. The mega battery and pcc can be found at happy vapor I am sure but I have no idea if HV carries the mega pcc.
What I find helps if I am hitting it too hard is put it in a pocket or out of site. Us humans can become distracted very easy and you should start to forget about it when you cannot see it. As time goes on you will should not need it as often. I think it is very normal for new vapors to vape heavy in the first few months. I know I did.
Anyway, hope this helps, it is late, night.
