Been mech modding for a few years now but am looking to get a box soon. My preferred coil is a nichrome 80 24ga dual parallel at around 3/32 diameter. Ohms in around .131-.145. Would I still need the same battery that I use in my current rig or can i get lower amp with greater mah? Now using sony vtc4 but started using mxjo as the sonys cycle out. Mxjos last alot longer and dont get as warm as the older sonys, where as the newer sonys tend to get hot fast and don't hold up as long.

What box mod are you thinking of? And what kind of power are you planning on using?
With variable wattage mods the resistance of the coil has nothing to do with how much current is drawn from the batteries. The watt setting and battery voltage determine battery current. In order to determine whether you should use 20 or 30 amp batteries we need to know what mod (single or dual battery, series or parallel if dual) you'll be using and the watt range you'll be using.
LOL. Great minds think alike.
Thinking a sig 150 tc but still unsure. Looking at everything before I decide. The one I tried I liked at about 105 watts with my velocity. I get pleurisy often and warm to hot vaping helps so I may jump it up to 140 or so every so often.

Newer Sony's are not Sony's, because Sony no longer makes 18650 batteries. They are rewrapped LG's from what I have heard. I just got a Samsung 25r5 for a 30w mod and the battery life is great so far. This is a 20A 2500mah. 25r5's are a very popular battery. Just a thought.
If you're looking at something along the lines of a Sigelei 150, the IPV4, or the Snowwolf like I think you are, then 20A batteries are sufficient.
One very important thing to point out... ...you shouldn't use your old batteries in a series mod when you can help it. It's standard practice to marry batteries for series mods and only use them in series mods. If they aren't discharging evenly, then they tend to burn one another out. The weaker cell gets charged by the stronger one. Reverse charging is not good for your batteries. It has a cascading effect. The more you run them like that, the harder the strain gets.
You'll get a longer lifespan and better capacity using batteries that are exactly the same age, have seen exactly the same wear and have always been charged together. Its not super dangerous if you don't always use married batteries, but it's still much more ideal in the long run. Batteries are cheap. Drop the 24 bucks on two pairs of new batteries for better, more consistent performance.
High-powered series mods only pull the current they need to generate the raw wattage at the batteries' voltage... ...and they don't need much when you have 8v of push. Voltage can be converted to current as needed, so you can pull 20 amps from your batteries in order to push 38 amps to your atty at a lower voltage.
This also means that current draw increases as battery voltage decreases. To run at 150w, a reggie box will pull 20 amps from fresh batteries and 27 amps from batteries approaching the low voltage cutoff. For 100w, it's 13 amps fresh and 20 depleted. At 75w, its only 10 amps fresh and 14 depleted.
25r's would be fine a fine choice if you're mostly vaping at 100w or less. Any more than that and you are going to start approaching or even surpassing the 20A CDR at some point, but not to a battery venting degree. The strain is going to be pretty minimal for new batteries. Capacity will decrease noticeably, though I'm willing to bet that most 30A batteries still will not last as long. You can run newer, trustworthy 20A cells up to 150w with no worries.
I have 25r's and VTC5's, which I often run at or above 100w. The Samsungs are the winners, hands down. They last much longer.
For 100w and below, I'd highly recommend the Samsung 30Q's. They're 3000mah, 15A batteries, but they can handle 20 amps more than adequately. When you start pulling over 15 amps, I believe the capacity dips to around 2500mah, which still isn't too bad. And they last much, much longer than the 25r's at under 100w. If you want a battery that will last forever at a lower wattage, but will still be usable at a higher wattage, it's a great battery.
