NiMh & NiCd Delta Peak Sensitivity Setting

This feature sets the cutoff voltage for the automatic charge

termination of a NiMH and NiCd battery pack. The setting can

range from 5 to 20mV per cell, the default is 12mV for NiCd

batteries and 7mV for NiMH, the parameters are set individually

for NiCd and NiMh batteries. If the cutoff voltage is too high,

there is a danger of overcharging the battery, if it is too low there

is a possibility of premature charge termination. Refer to the

battery manufacturer’s specifications to determine the proper

setting. Once you have established the desired settings press

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

the next parameter.

Capacity Cutoff Setting

The charging software allows the user to create a maximum

charge capacity protection setting. If the delta-peak voltage is not

properly detected or the safety timer times out, the charge process

will stop automatically when the battery reaches the set maximum

charge capacity set by the user. Once you have established the

desired settings press

Start/Enter to confirm the setting then press

INC to move on to the next parameter.

Sound Settings (Key & Buzzer Mute)

A beep sounds to confirm the every time the user presses a button,

additionally a sound is emitted during the operation of the charger

to confirm a different mode change. These functions can be

switched on or off. Once you have established the desired settings

press

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

to the next parameter.

Low Input Voltage Setting

This function monitors the input voltage of the DC power source

used to power the charger. If the voltage is lower than the user

setting, the program will end forcibly to protect the input source.

Once you have established the desired settings press

Start/Enter

to confirm the setting. You have now set the initial user settings.

You can repeat this procedure for the other Channels.

Temperature Cutoff Setting

You can choose whether or not you want to use the automatic

temperature cut off when using the optional temperature

sensors. When turned on you can set the maximum temperature

at which the charger should allow the battery to reach during

charging. Once a battery reaches this temperature, the charge

or discharge process will be terminated to protect the 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.

Waste Time Setting

When charge/discharge cycling a battery the battery will become

warm. You can set a time delay ranging from 0 to 60 minutes

after each charge/discharge process to allow the battery to cool

down before starting the next charge/discharge cycle. Once you

have established the desired settings press

Start/Enter to

confirm the setting then press

INC to move on to the next

parameter.

Safety Timer Setting

When the charge process starts, the integrated safety timer runs

simultaneously. If an error occurs or the charge termination

circuit cannot detect if the battery is fully charged, this setting will

terminate the charge process to prevent overcharging. Use the

Safety Timer Calculation below to determine the proper setting.

Safety Timer Setting Calculation

To determine the correct safety time setting when charging NiCd

or NiMH batteries, divide the capacity by the current, and then

divide the result by 11.9. Set the results of this calculation as the

number of minutes for the safety timer setting. If the charger

stops at this time threshold, about 140% of the capacity will have

been fed into the battery.

Example: 2000mAh 2.0A

(2000/2.0=1000)/11.9=84 minutes.

CONNECTING THE BATTERY

WARNING

Before connecting a battery, it is absolutely essential to check that you have set the

parameters correctly. If the settings are incorrect, you can damage the battery and create

a dangerous situation that could result in serious damage or injury.

Connecting the Battery

To avoid creating a short circuit between the banana plugs always connect the charge

leads to the charger first, and then to the battery. Reverse the sequence when disconnect-

ing the pack.

Connecting the Balancer Socket

These pictures show the correct way

to connect your battery to the Hitec

X4 AC Plus for charging in the

balance mode. The balance socket

attached to the battery must be

connected to the charger with the

black wire aligned with the negative

marking. If your battery’s balancer

socket does not fit in the socket

make sure to use the proper adapter

board for you battery type.
