Skyrc e4 Instruction Manual

INSTRUCTION MANUAL
Thank you for your choice of the SKYRC
e4, 12 V fast charger. This unit is simple to
use, but its operation does require some
knowledge on the part of the user.
These instruction manual is designed to
ensure that you quickly become familiar
with the charger's features and how to
operate it in the proper way.
1. General Description
The SKYRC e4 is a low-cost, high-quality
12 V DC fast charger, designed for charging
lithium batteries of up to 4 cells.
The charger includes an integral balancer.
The charge current varies within the range
of 100 to 4500 mA.

The recommended charge rate is 1C
(battery capacity = charge current)
1C means: capacity value = charge
current.
*Example: LiPo cell of 2200 mAh

3. How to Connect the Battery
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.
4.The Charge Procedures
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.
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.
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.
