Need Advice On Topping Off Boge Cartomizers

[Taulid]

I'm using Boge standard resistance single coil cartomizers with my Lavatube. When the material gets white I add a couple drops, is it necessary? And what's the safe voltage to use? I read 3.2-4.2 is a good range, I don't want to burn it out.
Thanks

"Standard Resistance" does not really tell me the Ω of the carto, they vary from batch to batch. Check the Ω and adjust the voltage using this chart as a reference. Adjust up or down as needed. Also if you use a tank you don't to top off the carto. JMHO

Great exactly what I needed, it said 2.9 Ω. Ty
