Whenvapingathighpoweritisstronglyrecommendedthatonlythebestinclassbatteriesareusedand
thatallcontactsarekeptclean.
Theboxisequippedwithdifferentkindsofpowerreductionmechanismstokeeptheoperationinasafe
regionforthebatteryandtheelectronic.Ifthepowerisreduced,theactualpoweroutputisdisplayed
insteadofthesetpoint.
1.Theoutputcurrentislimitedto22A:Whentheatomizerorcoilresistanceiscomparablylowandwhen
thepowerissettohighvalues,theactualoutputpowerwillbelimitedaccordingtotheformula
Example:Rcoil=0.12 =>Pout,max=(22A)²*0.12 =58.8W,regardlessofthepowersetting(unless
itislowerthan59W)
Thelimitationworksdynamically,i.e.ifthewirechanged(e.g.aTC-wire),thelimitationwill
adapttothis.Duringlimitationthedisplayshowsa atthepositionofthebatteryvoltage
display.
2.Theoutputvoltageislimitedto11V:Whentheatomizerorcoilresistanceishigh,powerislimited
accordingto
Example:Rcoil=1.8 =>Pout,max=(11V)²/1.8 =67.2W
Thelimitationworksdynamically.ForexamplewhenusingaTC-wiretheinitialpowercanbeveryhighand
assoonasthewireishot,thepowerwillbereduced.Duringlimitationthedisplayshowsa
3.TheoutputpowerislimitedifthesourceresistanceRb(batteryinnerresistanceincludingcontact
resistancesandinternalwiring)ishigherthan36m Duringlimitationthedisplayshowsa
4.Theoutputpowerisreduced,whenthebatteryvoltagedropstoavaluedependentofparameter
Ubat,min(range2.5to3.0V)accordingto theformula
Pout,max=thelowerof[80Wand10W+(UbL-Ubat,min)*10W/0.1V]
Example:Ubat,min=2.5V,UbL=3.15V(batteryvoltageincludingdropduringpoweroutput)
=>Pout,max=10W+(3.15-2.5)V*10W/0.1V=75W
Notethatthepowerislessreduced,whenthebatteryinnerresistanceislow.Alsonotethatpoweris
reducedonly,ifthebatteryvoltagedropsbelow3.2V(atUbat,min=2.5V).
Duringlimitation,thedisplayshowsa
Alwayskeepinmindthat80Wtakenevenfromahighdrainbatterywill
createpowerlossesinthebatteriesinnerresistanceaswellasatallmechanicalcontacts,whichfinally
willreducethetotalvapetimeandleadtovoltdrop.Thepower-lossesinsidethebatterycanbesignificant
asasimplecalculationshows:
Example(neglectingefficiencyofelectronic):
Innerbatteryresistance25m
Voltageatbatteryunderload3.3V
OutputPower80W
Thiswillpreventtooverheattheliquidandhelpavoidingthecreationofhazardoussubstances.
