Well... they are low resistance atomizers. Less than 2 ohms. That means that, at the same voltage, an atomizer will draw more current. More current means more heat.
For example let's take a regular Joye 510 atomizer at 2.2 ohms.
Your 3.7v battery charges to 4.2v and you might be getting 4v with it fresh.
2.2 ohms at 4v = ~1.8A or about 7.27 watts (heat)
Now let's take the same atomizer at 5v (using your altsmoke pt with a good power supply.
2.2 ohms at 5v = ~2.27A or about 11.36 watts -- yummy
Now we'll use a LR 510. Let's guess it's about 1.8 ohms
With your fresh 3.7v battery delivering 4v we have
1.8 ohms at 4v = ~2.2A and about 8.89 watts -- still acceptably yummy
So you've achieved a very nice vape with your (single) 3.7v battery.
Note: you can get 5v with a pass through. When you go to stacking batteries you're going to be getting over 6v which is a bit too much juice and too hot. (besides, the protected batteries will trip with a regular 510. You have to use a higher resistance atomizer.
No, you don't want to use your LR atomizer with anything higher than a 3.7v battery 'cause you'll probably burn it out in very short order.
So what's the big deal about the LR atomizers? You can get very close to a higher voltage vape using your plain ole protected 3.7v battery. Safe, easy to get, you already have them, no worries.
