Well damn, i've been thinking this whole time i needed to wait to get an eGo at least to run a LR atty, but im assuming this means i can use one on a regular 510 batt?
Yes and no...
It would work, but the question is how long and how safely?
See, LR atties draw more amps from the battery in a shorter period of time.
If a battery is asked to dump out more power than it has, it can lead to an explosion.
Since these things are in your face, why take chances?
Mind you, most ecig
batteries have protection built into them so they will hopefully shut themselves down before this happens.
The next issue that could pop up...assuming your battery can handle the drain...is the switch. LR stuff might pop the switch if they draw more amps than the switch can handle.
Assuming you never have either of the two problems above, LR will shorten the life of your battery. On the other hand, it can lead to shorter draws to get the same amount of vape...so it might even out for you. Mileage varies. It might also cut down on the number of succesful charge cycles you get.
All that being said, you could probably run the 2ohm stuff ok. I wouldn't push it and go below that.
If you're on a budget...consider grabbing an inexpensive eGo USB/Passthrough battery. 650mah battery, a built in charger, and a USB cord. Some even come with the cone. That gets you 4 to 6 hours of battery life, plus you can use it while it's charging. They run on average at $25. One of the best values in the ecig industry...no need to buy chargers and junk to go with it

Also, I'm lead to belive that you can charge the eGo batteries on your regular 510 charger provided it has room to screw it on. It'll take much longer to charge than it would on an eGo charger...but hey, it's only a buck or two more than a 510 mega battery and is almost twice the capasity
The small eGo battery is probably going to tip the scale about the same as a mega battery in weight. It's just a little fatter.
