Ive noticing some of my batteries dont have as much life as they once had. I would want to get some new VTC4 or 5s but the market is so flooded with "clone" batteries. I have been getting crazy with my builds lately claptons fused claptons an so forth .So what other good batteries should I get for sub ohm build usually around .15-.5? Any suggestions greatly appreciated.

My daily drivers are Samsung 18650-25R's and they work perfectly, last longer then my old VTC5s and they don't get warm
Thanks I will check it out I have never heard of the orbtronics. I am on a budget this week I was hoping to pick up a pair or two this week I have been looking at the mxjos. Because all my b&m's carry them so I figured they might be hot stuff. But I heard they are rewraps?

What is the continuous discharge on those I vape on mech occasionally now I usually use my sigelei 100w now tho?
20A continuous, 100A pulse (1sec). These are suitable for both sub-ohming on mech's as well as your sig 100w.
Samsung 18650-25R's seem to be the gold standard of best bang for your buck in terms of batteries so you can count on my vote for them.
Orbtronics sx30s are on sale for ten bucks at orbtronic.com. I'm a battery newb but thats what I got for my ipv4 100 watt mod. 30a continuous
There are no 18650 batteries on the market today which are more than 30 amps continuous. The lowest ohm build a 30 amp continuous battery should fire is only 0.2 ohm. (And that is without any safe headroom)
Please be aware that some manufacturers and vendors advertise what is called a "pulse" amp rating. As vapers, we should ignore pulse ratings, because that could be anywhere between 1 - 30 seconds, depending upon the manufacturer. The spec is dubious at best, and should not be used.
Continuous, or the maximum continuous discharge rating, is what we should pay attention to when comparing battery specifications between brands and models. This spec is the industry standard.
Continuous Discharge Ratings vs Pulse (Burst) Discharge Ratings
The "continuous discharge rating" in amps is the standard specification for amp limits within the battery industry. It is a determination made by the manufacturer and represents the amp limit a battery can be safely used before it will fail.
The "pulse or burst" discharge rating is not a specification standard within the battery industry. Every manufacturer or vendor seems to have their own definition of what the pulse rating is.
A pulse discharge rating is any use above the continuous discharge rating. It is never safe and not within the intended operating parameters of the battery. You should not operate your device above the continuous rating if you can help it. The pulse rating is a condition in which the battery is on basically a buildup to failure. It is exceeding the sustainable and intended discharge rate of the battery. It is inappropriate for a consumer device to operate in the pulse range of its battery.
Which would be why we shouldn't rely on any pulse rating. Any failure, mechanical or electronic, that fires the mod will operate in the 'continuous' mode. If your setup relies on a pulse rating, it's instantly over spec.
If your amp draw is safely in the continuous discharge range, your coil could act almost like a fuse and burn out before the battery is stressed. If you are already running the battery at the edge of it's limits (pulse), there is no margin of safety.
I am of the mindset that you should leave a margin of safety when deciding what resistance coil to use. We probably place too much faith into cheap ohm readers in being precise and accurate. Also, a RDA's post screw unknowingly coming loose can greatly change the coil's resistance.
Everyone is free to set their own parameters, and I can only say what mine are.
I try to never exceed 50% of the CDR (continuous discharge rating) of a fully charged battery (4.2v). So with a 20A batteries, that would be 10A. The above Ohm's Law Calculator tells me that a .4 ohm 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, your 20A battery may only be a 10A battery.
1.0 ohm = 4.2 amp draw
0.9 ohm = 4.6 amp draw
0.8 ohm = 5.2 amp draw
0.7 ohms = 6 amp draw
0.6 ohms = 7 amp draw
0.5 ohms = 8.4 amp draw
0.4 ohms = 10.5 amp draw
0.3 ohms = 14.0 amp draw
0.2 ohms = 21.0 amp draw
0.1 ohms = 42.0 amp draw
