1. Instruction
Cellmeter8 isa cleverdevicethatcan showyou the condition ofyourbatterypacks,
Itcan be used with the mostcommon batterytypesused forthe rc modeling namely
LiLon(Lithiumlon)
LiPo(LithiumPolymer)
LiFe(LithiumFerrite)
LiHV(High Voltage LithiumBattery)
NiCd(NickelCadmium)
NiMH(NickelMetalHydrate)
LithiumBatteryTypes( Lipo.Li-Ion,LiFe, LiHV)withoutthe need forthe additionalpowersupply,
CellMeter8cansupport 2S-8S,Test1S Lithiumbattery,you need toaccess morethan 3Sof
NickelBatteries, or5VUBECtoNiCd/MHport forthe Cellmeter8 to provide working power

2. ConnectingABatteryPack
Cellmeter8 there are two batteryconnection ports:
The connecting port ofthe LithiumBatteryis9pin,2.54mm,Can be directlyinserted intothe
2.54mm ofthe lithiumbatterypack balance line plug, Connectthe batterypack to the plug,, the
negativeelectrode ofthe balanced line plugisalignedwiththe cellmeter8Lithiumport
(negative Location close to the NicD/NiMHport)
NickelBatteryconnection port specification for3pin,2.54mmspacing. Can be directlyinserted
intothe spacing ofthe mainline of2.54 mmnickelbatteries,The mainline ofthe nickelbattery
pack isconnecting the plug ,Theposition electrodeshouldbealignedwiththe3pin
