Okay so I've been vaping for awhile now and I'm interested in getting into series boxes. Right now if I'm understanding correctly I know that you have to have a build that's is lower amps then the batteries continuous maximum discharge current . So if a battery has a continuous maximum discharge current of 20 a. I just have to keep it under that and I'll be safe? So like 8.4/.5 is 16.8. So as long as I don't go lower then .5 I won't have any problems???
On a series box mech, wether with or without a PWM potentiometer, safest lowest build is 0.55ohm (at about 75% of the max CDR of about 15 to 16amps on a 20amp battery yes), suggested build would be about 0.75ohms (11.2amps), that is assuming just straight battery through only a Mosfet chip or direct current like the Wismec Noisy Cricket. If it comes with a dial (PWM Potentiometer) example the Hexohm, you have a little wiggle room, but still suggested to run lowest 0.5 to 0.55ohms. Series regulated like the Sigelei 150watt for example, basically the only limit is what the chipset can handle and your batteries, 2x 20amp batteries then it is 120watts about max (about 60watts per battery), true 30amp like the LG HB6 then about 170watts (170watts/6.4v (lowest battery charge 3.2v each battery)=26.5625/90%mod efficiency=27.2139amps) (about 96watts per battery)
