Skyrc e4 User manual

First locate the power jack on the front
side of the charger, and connect it to a
12 V lead-acid car battery or 12 V AC/DC
Adaptor. The charger is now ready to use.
The lithium battery is connected to the
battery sockets on the right-hand side of
the case using a charge lead terminated
in banana plugs. When connecting the
pack take care to maintain correct
polarity (red = + terminal / black = -
terminal).
The charge output is protected against
reverse polarity and short-circuit, but it is
always best to avoid these errors, and to
correct them immediately if they do occur.
The balancing cable is connected to the
correspondent balancing socket. Both charge
lead and balancing cable must connect to the
charger at same time.
The correct charge current must be set
before you initiate the charge process.
This is carried out by rotating the adjuster
knob on the front panel to set the charge
current to suit the battery (100 … 4500
mA). Usually we are using “1C” to
charge the battery.
3. How to Connect the Battery Start the charge process with a press on
the Start/Stop button. You can stop the
charge process at any time by repeatedly
pressing the Start/Stop button again.
4.The Charge Procedures
This is the correct charge current for the
most popular types of Lithium batteries.
Naturally, the charger can cope with
packs of higher capacity, but the charge
time is proportionately longer. Certain
high-performance Lithium batteries can
be charged at rates higher than 1C.
Please read and observe the datasheet
provided by the battery manufacturer.

INSTRUCTION MANUAL
The recommended charge rate is 1C
(battery capacity = charge current)
1C means: capacity value = charge
current.

Ensure that there is an unrestricted
airflow to and from the charger's cooling
slots. Never place the charger on a
carpet or similar surface.
Packs to be charged as a unit must
consist of cells of the same maker, the
same type and the same capacity.
Take great care to maintain correct
battery polarity, and avoid shot-circuit.
Read the battery manufacturer's
instructions and adhere to them strictly.
SKYRC e4 is suitable solely for charging
rechargeable Lithium batteries. Do not
attempt to recharge dry cells. Charging
other types of batteries may cause fire or
explosion.
Do not leave the charger operating
