A few observations:
I picked up some Joye 510 attys from HG a while back to see how they compared to my 901's. I didn't buy any 510 batts, however, as I already had a 510 Bartleby and figured the 14500 would be a better choice anyway.
I've been vaping a rather dark (but extremely tasty) tobacco/menthol blend that was building up on the atty within a day or so and knocking down the performance. Suddenly I was a losing a 510 atty every few days (some quit while vaping - others died while trying to clean them). My first thought was that I'd just gotten a bad batch of attys, but when the trend continued after a subsequent order I had to re-think everything (and yes, I was keeping them nice and wet).
As I stated earlier I didn't have any stock 510 batts to try, but I did have plenty of 901 auto batts and an adapter, so I hooked one up and started using it. I don't have the equipment to measure the voltage, but I could quickly tell that the e-liquid not only had more flavor, but that the atty wasn't getting as hot as quickly. Right now I'm on day five with this particular atty and it's still performing well. I also used an adapter to try stock 401 auto batts with the 510 atty and found that the performance was closer to the Bartleby (hotter atty with harsher taste).
Conclusions:
1. With at least certain juices, lower voltage is preferable with the 510. If the atty gets too hot in use it can bake the juice to the coil - making if difficult if not impossible to clean. It also seems to cook off the juice quicker and gives a harsher taste.
2. 901 attys seem to perform better over-all at 3.7v. I've been using a 901 with several different juices from different vendors on the Bart for months with no ill effects. In fact, I find that the higher voltage brings out the flavor of most juices better. I've also found that the 901 is more robust at higher voltage than the 510.
3. While I cannot measure it (yet), the stock M401 batteries seem to put out more voltage than their 901 counterparts. I'm waiting on some manual M401 and 901 batteries and will try to meter them when they arrive. The "in-use" difference, however, is pretty obvious.
Just my two cents...
