So I definitely want the series, since it gives me more room to play around with.The Samsung 25R has a 20 amp CDR (2500mAh). The LG HG2 and Samsung 30Q (3000mAh) both have the same CDR but slightly better mAh.
With a parallel configuration you get between 75-100% of the combined CDR, so with 25R that's between 30 and 40 amps to work with.
So using Ohms law 0.14 ohms at 4.2v will draw 30 amps from the combined pool giving you 126 watts.
With series configuration the voltage is doubled to 8.4 volts, but the individual CDR applies. You can use a higher resistance range for this configuration.
0.56 ohms at 8.4v drawing 15 amps giving you 126 watts.
Though in practice the Wattage will be far less than this due to voltage drop and battery sag. Both these builds will have the same runtime. Of the two I prefer series for instant ramp up and avoiding super low resistance coils.
I'll probably build with 24. I've been using steamengine to do some theoretical builds, like a quad coil at X amps, R Resistance, W watts H heatflux.. and havent found any builds i like much. Looks like Ill be sticking to dual coils. They make my head hurt less. I've been finding that with any more than 8 wraps, the wick starts burning in the center as the juice evaporates. Just something Ive been noticing. I'm thinking, about another 3 or 4 months before I am comfortable trying builds on those dual cell mechs. I need to know everything in advance to cut the risk factor as much as possible.
I've been considering that one. I'll have to take a closer look.Get flexible...grab You a Noisy Cricket II!
Parallel mechanic, serial mechanic...or with batteries serial configured even voltage controlled!
Mine is on the way from China to Germany...in few days i will have it in my hands.

JayBo...he is NOT an idiot...
Sorry, i am a Fasttech-junkie, because: Germanys stores are too expensive for me...and: Fasttech is really reliable. Delivers in a maximum of 3 weeks...it is always like christmas!
Like my "old" Cricket...very much. Serial has something special...but take care of what batteries You use...and everything else! Not a toy. Short circuit would grill Your hand inside-out.
Troll with dual coil...0.25 Ohms...2x VTC5A...wooohaaahey! That fluxes even with HUGE coils...very, very hard. 2 seconds puff time...maximum.
Yes I have. Have you read it though, particularly the disclaimer about safety and experience levels?
I'm experienced enough, just not with 2 cell mechs. Hence looking for all the info I can get before using. I'm determined not to use a hybrid. I see no reason to take extra risk for a fraction of a second battery lag. The difference in performance just isn't worth the extra risk.
