Historically the problem with LR and Rivas/eGos was related to the surrounding electronics.

At least in the eGo case the problem was a MOSFET switch that was rated for 2A. If you went to "real" LR, down near 1.6 - 1.7 ohms, the current draw would notionally be 3.2V/1.6 ohms = 2A, borderline for the MOSFET. People did lose eGo batteries due to MOSFETs failing (there's engineering variability, so any given MOSFET might have done okay, while another one would fail, and there's variability in the resistance of cartos, both between two cartos and over time for a single carto).

A 2 ohm boge is within the safe zone, as I believe even latest Rivas top out at about 3.7V fresh off the charger, and they may well have a different MOSFET anyhow.

Like I said, there's probably been design change. LRs were just popping up last Summer and Fall, people were definitely getting failures. Back then the Rivas were regulated 3.2 - 3.4V, like eGo (though I don't believe they used eGo PWM).

This occured back in the dark ages, BSF (Before SwedishFish) :)

That's funny!

OT- one of my very first batteries from my Joye kit still works. Granted, I lost it for a couple months and found it again. :laugh: Now if I can find a bottle of juice that somehow disappeared, I'll be happy.

The 2.0 ohms will be fine. I regularly use the Smoktech 1.7 ohm cartomizers from CCV and haven't killed a battery yet. Whatever problems they had with the larger batteries seems to have been fixed.

Now using them on the thinner batteries (less the 650mAh) I'd suspect might be a problem.

I've done it. I bought a few boxes of LR and SR and put them both in a storage container and then realized I couldn't tell them apart.

I definitely wouldn't recommend it to anyone but did use the LR on my 510. I'm sure it didn't do the battery any good.
