INTRODUCTION

Thank you for your choice of the SKYRC e455, 100-240V AC balance charger. This unit is simple to use
but its operation does require some knowledge on the part of the user. Please read this entire operating
manual completely and attentively before using this product, as it covers a wide range of information on
operating and safety.
SKYRC e455 Charger is an economical, high quality 100-240V AC balance charger, designed for
charging LiPo, LiFe and LiHV batteries from 2-4 cells in balance mode. It can charge 6-8S NiMH batteries
also. The circuit power is 50W and max charge current can reach to 4A. There are four kinds of charge
current 1A/2A/3A/4A that can be selected. You could select the proper charge current according to battery
capacity.

OPERATION

SKYRC e455 comes with the built in power supply. You can connect the AC power cord to the AC
socket(100-240V AC) directly.
Please refer to following steps to charge the battery,
1) Insert the AC power cord into the charger.
2) Insert the AC cord into a wall socket (100-
240V). The battery type LED and the charge
current LED(default 2A) will glow constant
white.
3) Connect battery balance wire to balance port
which is in front side of the charger, select the
battery type LiPo/LiFe/LiHV by pressing the
"BATT" button. Select Battery Type
- 1 -
4) Select the proper charging current 1A/2A/3A/4A by pressing the "A" button.
The charge current varies from 1A(1000mA) to
4A(4000mA). The recommended charge rate is 1C
(battery capacity = charge current). 1C means:
capacity value = charge current.
Example: LiPo cell of 2200mAh Capacity; 1C=2200mA
(=2.2A) charge current. You can choose 2A
current to charge the battery.
LiPo cell of 2800mAh Capacity; 1C=2800mA
(=2.8A) charge current. You can choose 3A
current to charge the battery.

Charging LiPo/LiFe/LiHV Battery

Connect the battery main charge lead to battery socket which is in the front side of the charger and
battery balance wire to balance port which is in the right side of the charger.
Press and hold "A" button for 2 seconds to start charging. The charge status LED will glow to indicate
charging is in progress.

EXPLANATION OF LED STATUS

Remark:
The capacity indicator LED flash times shows the charge current you set.
1A Flashes white ONCE and stop 1 second in cycle.
2A Flashes white TWICE and stop 1 second in cycle.
3A Flashes white THREE TIMES and stop 1 second in cycle.
4A Flashes white FOUR TIMES and stop 1 second in cycle.
When the battery is fully charged, the charge status LED will glow constant WHITE. Unplug the
battery from the charger, the charger will be ready to charge another battery.

6) Charging NiMH Battery

Connect the battery main charge lead to battery socket which is in the front side of the charger.
Select the battery type NiMH by pressing the "BATT" button.
Select the proper charging current 1A/2A/3A/4A by pressing the "A" button.
Press and hold "A" button for 2 seconds to start charging. The charge status LED will glow to indicate
charging is in progress.
During the charging process, the capacity indicator LEDs will light up in sequence.
When the battery is fully charged, the capacity indicator LEDs will glow constant white.

WARNING:

Always make sure you are charging NiMH battery under NiMH mode. Charging Lithium
Battery under NiMH mode can lead fire, personal injury or property damage.
