I am going to fill a 2.4 in a couple hours with .5 gram on a new cartridge. If it hits fine, i am going to add the 2nd 2.4 and try it double barrel.
I think i got it right this time with weighing the cartridge first so i know how much is in there.
Any other tips?
Be sure your concentrate is 'clean', run a foil test if necessary. Be very careful to properly preheat the center section before melting the load down. Never dry fire carts (which includes 'pre oxidizing').
FWIW, I'd concentrate on learning how to use the 2.4s one at a time. Not only can they produce some very impressive vapor if heat is managed well, but it takes some considerable skill to get two carts running identically (or nearly so) at the same time.
As a guess, only a few percent of folks use them. For instance, in all the discussion of failed heads I don't think I recall a single dual head dieing. Most guys use them as backup when the normal one fails and needs replacement....meaning they were using the single the most.
That's interesting. I guess maybe a single cart only uses half the available power from the batteries, then? There must be some limit to the power output from a given battery configuration, right? So if one cartridge uses full power, how do you get power for the second without dividing the available energy between them?
That's perfectly normal for electricity. There's a limit to the total power for your house, but turning on another lamp doesn't dim the others. Up to the maximum total (when the system fails) each load gets all the power (current) it wants according to Ohm's Law.
Looked at the other way the battery has no idea what the load is, only the total current (in Amps like fuses and circuit breakers) is. If it can, it will provide it.
