First, you need a ohm reader if you are going to rebuild.
You are going to want a safe-chemistry, high-drain battery with a high CDR. How high? I'll quote @tj99959 as this is the practice I follow with regards to amps & headroom.
When considering how low you can build you need to give yourself some headroom. I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A battery (like the Samsung 25r), that would be 10A. This Ohm's Law Calculator tells me that a 0.4Ω build is as low as I would want to use.
The reason that I place a 50% limit is because as a battery ages the mAh of the battery degrades, as the mAh degrades so does the batteries c rating (amp limit). So down the road, a 20A battery may only be a 10A battery."
With a 30A battery, 0.28Ω is the lowest I would build.

I highly recommend you spend some time with @Baditude & @Mooch (two of our resident battery/safety experts) and visit their blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.
Here are links to some of Mooch's blogs:
* No matter what is printed on the battery wrapper: There are no 18650 batteries with a genuine rating over 30A!
* Links to all his battery tests to date: List of My Battery Tests
* Picking a Safe Battery to Vape With: Table of 18650 Battery Safety Grades
Baditude's Blog - Table of Contents: The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:
BATTERIES
Battery Basics for Mods - The Ultimate Battery Guide
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.
Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.
OHM'S LAW
Ohm's Law Explained for Vapers
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.
Explain it to the Dumb Noob: Ohm's Law Calculations
* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.
BATTERIES - WHERE TO BUY
Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.
* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

Get yourself an an iStick30 & an Atlantis to vape while you're learning what you need to learn BEFORE you pick up your Manhatten & dark horse.
I traded a bow for the mod and RDA (thats how i ended up with it) and I have a itaste ep with a kanger aerotank that I use all day at work until I get home and then I switch to the Manhattan. I'm just wondering what battery is good because I would like to buy more so that I can drip all day on the weekend with out having to go back to the itaste in the middle of the day

I think you're not 'getting it' Reyray. What battery is good in a mechanical mod depends on the resistance of your build. The lower you go the more amps will be drawn from your battery. With a regulated mod like a Sigelei box resistance doesn't matter. You set the watts (power) and the mod doesn't let the battery see more than that no matter what the atty resistance is.
Susan gave you a bunch of links that have all this info in them. If you have more questions fire away
