Lithium battery (LiIo/LiPo/LiFe) program These programs are only suitable for charging and discharging Lithium batteries with a nominal voltage of 3.3V, 3.6V or 3.7V per cell. These batteries need to adopt different charge technique is NiCd LiPo termed constant voltage(CV) and constant current (CC) method. LiFe Pb The charge current varies according to the battery capacity and LiIo SETUP performance.

'STORAGE' program for Lithium battery This is for Lithium battery not to be used for long time. The program will determine to charge or discharge the battery to a certain voltage depending on the voltage of the battery at its initial stage. The final voltage are different from type of batteries, 3.75V for LiIo, 3.85V for LiPo and 3.3V for LiFe per cell. If the voltage of battery at its initial stage is over the voltage level to storage, the program will start to discharge.
Safety programs for all types of battery - Max. capa. (Maximum capacity) : You can define the maximum capacity which can be charged or discharged by the form of a percentage of battery capacity set in the top of display. If full-charge has not been detected for any reason, the charger limits the quantity of feeding energy by the value and terminates the process as on the value is reached.
NiMH/NiCd battery program These programs are for charging or discharging NiMH (Nickel-Metal-Hydride) or NiCd (Nickel-Cadmium) battery commonly used for R/C model applications. The charge NiCd LiPo current varies according to the battery capacity and LiFe Pb performance. The type of battery which is either NiMH or LiIo SETUP NiCd must be correct for the battery being charged.

Pb (lead-sulphuric acid) battery program This is programmed for charging Pb (lead-acid) battery with nominal voltage from 2 to 28V. Pb batteries are totally NiCd LiPo different from NiCd or NiMH batteries, but very similar with LiFe Pb Lithium batteries. They can only deliver relatively lower current compare to their capacity, and similar restrictions definitely LiIo SETUP apply to charge. So the optimal charge current will be 1/10 of NiMH REVIEW the capacity. Pb batteries must not be charged rapidly.

Warning and error messages BC8DX incorporates a various functions of protective and monitoring the system to verify functions and the state of its electronics. In any case of occurring error, the screen displays the cause of error that is self-explanatory with audible sound. Check connection ... Reversed polarity The output is connected to a battery with incorrect polarity. STOP/ESC Check charger ... Over-temperature The internal temperature of the unit goes too high. Cool down the unit.
Glossary of terms Amps(A): The unit of measure for charge or discharge electric current. The program of the charger will show most of the current in amps(A) at its LCD screen. Milliampere(mA): The electric current, being amps(A) multiplied by 1000 and noted as 'mA'. So 2.0A is the same as 2000mA (2.0x1000). Or, to convert mA to amps, divide the mA number by 1000. So 200mA is the same as 0.2A. If a current value is below 1.
Maximum circuit power chart For the voltage of battery is more than 16V, the actual amount of charge current feeds to the battery might automatically be limited, so not to exceed the charger's maximum rated charging power of 160 watts at an output channel. And also, for the battery having more than 5V, the discharge current delivered to the battery might be limited by the maximum rated discharge power of 25 watts per output. Maximum charge/discharge current at 12V DC input NiCd/NiMH LiPo LiFe Pb No.
