Yes lower amp drain for the desired wattage , the battery will last longer, with the same wattage output. So for your calculation figure your true watt range that you vape at. Go as high in ohms as you can and still get that range. To maximize battery life.
The amps are for max power, amp load calculations, watts are for equal power calculations. Volts can be thought of an end product setting(means to an end) to equal the others, or for backwards calculations.
Although it's not as big a deal since you use pretty low power as is but you can maximize the battery life. Possibly 25% longer with a similar vape at the same overall wattage. Based on what you've said I'm guessing 2 ohm at 3.7v & ~7 watts not really an issue unless you run single 350s then it could help you out a bit get another hour out of a battery maybe
** This is a bigger deal for those trying to run higher power like myself. Regularly running at 15 watts, or using lo w res coils. **
Yeah, totally undertand it's more for those who are building their own coils and/or vaping closer to the "extremes"..
As you mentioned, just looking to get as much as reasonably possible out of a battery charge, without sacrificing the juice-vape experience.. don't want to get caught with my pants down someday when I need a toot the most, heh
And yep, yer guess (7 watts/3.7v @ 2 ohm) would be correct! Sometimes I'll go up or down a little, but not by much
As a bit of an aside.. These Sigelei kit batteries (ICR) aren't the best.. Probably shouldn't be using them anyway, but considering I paid for them, might as well use them up..
The issue? With each successive charge, the life keeps going down down down... Guessing at some point a fully-charged 350 will last about 5 minutes, LOL.. I'm sure I'll dispose of them well before that.. I understand the increased risks with these.. not sure why they'd include them, anyway.. at least throw some eFest's in there, sheesh!
Great table, in any event...
