Thanks, I am going to try a bottom feeder and I use a Darwin now. The feeder has a 18650 2400mah batt in it what would you say I should use for attys or carto's LR 1.5? Been spoiled with the Darwin so don't know what to do with a fixed batt lol?
What Power setting do you tend to prefer on the Darwin?
You can use this
Ohm's Law Calculator to figure out what resistance atties will vape near your sweet spot on the 3.7v battery.
In the calc, put in 3.7v, then put in the power setting you like on your Darwin...the calc will figure out the rest and show the Ohms/resistance required to hit that power level. Note...unless the mod is regulated it might start off hotter than 3.7v right off the charger and gradually give lower and lower voltage and power/watts on the atty till it needs to be recharged.
Just as an example...
A 3.7v battery with a 1.5 Ohm atty is going to burn at around 9 watts and pull close to 2.5 amps.
Note, if you do end up going with LR atties on the 3.7v mod...check the amperage it's gonna draw with the calc and if it's above 2 amps, consider only using good IMR high drain batteries with a C rating to dump that kind of amperage on a regular basis. Keep in mind that a battery might be rated at 2400mah at currents of like 1.5 amps, but when the current goes up to over 2 amps, it might be more like 950mah. Also consider checking your batteries on a meter periodically to make sure they're not going bad on you. These things do spend a lot of time in your face so don't take any risks. Check about here on the ECF for good battery care tips on a mod that isn't voltage or power regulated.
One more reason I'm loving the Darwin...it's well overbuilt when it comes to my sweet vaping spots...and does all this for me
