Discharging

The main purpose of discharging a battery is to clean the residual capacity of the

battery or to reduce the battery’s voltage to a defined level. It is critical that the same

attention be paid to the discharging process as to the charging process. The final

discharge voltage should be set correctly to avoid deep discharging. Lithium batteries

cannot be discharged to voltage lower than the minimum voltage for the cell type.

Doing so will result in a rapid loss of capacity and/or total failure. Generally, lithium

batteries don’t need to be discharged and it is not recommended. If you choose to

discharge your lithium batteries make sure to pay attention to the minimum voltage

setting.

Some rechargeable batteries have a memory effect. If they are partly used and

recharged before the complete charge/discharge cycle is accomplished, they

remember this and will only use that part of their capacity next time. It is generally

known that NiCd and NiMH batteries suffer from this memory effect.

When powered on for the first time the X4 AC Plus will load a set of default parameters

most commonly used by most users. The screen displays the information in the following

sequence. The user can customize the parameters on each screen to suit their own

preferences.

To change the parameter values in the program, press the

Start/Enter key to choose the

parameter you want to change. Once the parameter is blinking you can change the value

with the

INC (up/forward) or DEC (down/back) keys. The value will be stored by pressing

the

Start/Enter key once and the blinking stops.

POWERING THE CHARGER

Main User Setup Screen

The first screen displayed is the Lithium battery set-up screen, you

can press

ENTER to bypass this screen and go to the next user

setup screen, or you can set the default Lithium battery type before

moving on.

The Lithium Battery Select Screen

Here you can choose one of the three kinds of Lithium batteries

supported by the X4 AC Plus, LiFe (3.3V), Lilo (3.6V) or LiPo (3.7V).

If you plan to use one type of Lithium chemistry battery you can set

the default here.

WARNING: Make sure when you connect your

battery that you have selected the proper type of battery before you

begin charging your battery. Once you have established the desired

settings press

Start/Enter to confirm the setting then press INC to

move on to the next parameter.

LiPo /LiIo/LiFe Check Time

To avoid an erroneous setting by the user the X4 AC Plus will

automatically detect the cell count of a Lithium battery at the begin-

ning of the charge or discharge process. To prevent an over-

discharged battery from being detected incorrectly, resulting in an

error, you can set a time limit for the processor to verify the cell

count. The default setting is 10 minutes which is typically enough

time to properly detect the cell count. It is not recommended that you

change this setting as setting to long of a “Check Time” can produce

dangerous results. Once you have established the desired settings

press

Start/Enter to confirm the setting then press INC to move on

to the next parameter.

WARNINGS AND SAFETY INFORMATION

DEFAULT USER PREFERENCES SETUP

The Hitec X4 AC Plus comes with a built in switching power supply allowing you to

connect it directly to a 120 VAC wall socket using the supplied AC power cord. The

charger can also be powered by a 12VDC car battery using the included large terminal

clips with matching 4mm female bullet connectors or it can be connected directly to a DC

power supply. When connecting to a battery or power supply it is critically important that

you use either a fully charged 12 volt car battery or a high quality DC power supply that

has a voltage range between 12V to 15V DC and a minimum current rating of 20A.

Failure to use proper input power can result in unreliable performance and may damage

the charger.
