I read in another post that using dual coil cartomizers can damage a Riva battery. Is this true? I bought some from FreedomSmoke just to try them, and they are low resistance (1.5 ohm) so I was planning to use them with my Riva.
Is there any danger of damaging the battery?
Also, what are the benefits/downsides of a dual coil?
From a rating perspective, dual coils are not magic. The Riva is shipped from liberty-flights with 1.5ohm addys. Whether it's rated for these or not I have no clue.
A unit like the E-power or NoEgo IS rated for addies as low as 1.25 ohm, and I'm sure there are many others.
You can get Dual Coil in 2.0ohm, and these days I'm leaning toward these.
The benefit is your not running a single coil at 1.5 ohm, you're running two at 3ohm, or two 4ohm for a 2.0 dual coil. More vapor, but no single coil is operating at 9 watts. They'll last longer than a standard LR addy, they're less likely to burn the filler material, they produce more vapor without flavor loss. There really is no down side, other than 1.5ohm is intense, and one generally downgrades their nicotine concentration.
