So i just received my roughstack from madvapes today, and was curious.. how long should i charge the battery (1200 mAH protected 18350 Li-ion batt) for the first charge? i dont know much about batteries so i didnt know if charging them longer on the first charge(past green) will help like i was told to do for my origonal 510 batteries. If anyone knows that would be sweet

No, once the charger light goes green, they are done 
NB The instruction to charge for a long time on the first charge to condition them is redundant even on the 510 - lithium ion batteries do not need that. It was necessary on old fashioned nickel cadmium rechargeables.

As soon as it hits green, it's done. This applies to all Li-ion rechargeable batteries, of all types, for all e-cigs, including the stock models such as a 510.
Li-ion cells are not like the old Ni-Cads, which were really picky about charging regimes. They don't need a long charge to start with, they don't need leaving on 'past the green', they don't need anything except basic good care - for example don't drop them. Li-ion cells are easy-care cells, it's one reason why they are so popular.
Who knows why these myths are perpetuated
Nothing happens anyway once a Li-ion charger takes the battery to its max, the charger just cuts out. In fact for safety there is a good argument that you should take the battery off-charge immediately it hits green, since a faulty charger can keep going over the top and deliver over-voltage to the cell. It's rare but does happen occasionally.
There are two things that you can do related to charging, that are of positive benefit, though:
1. Get a multimeter and check the voltage of the battery as soon as it comes off charge. It should be around 4.2 volts, and anything over 4.25 volts is a fault - it's too high. Be careful when doing this not to short the battery out, some Li-ion cell packages don't like this at all.
2. Don't fully discharge any type of rechargeable battery as that takes some 'life' off it. You can recharge a Li-ion cell before it is dead, and that will help it last longer.
