INTRODUCTION

Thank you for your choice of the SKYRC e450, 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 e450 Charger is an economic, 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 e450 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). All LEDS will light for 1 second and the
battery type LED will flash green and red which
indicates the charger is ready to charge.
3) Select the battery type LiPo/LiFe/LiHV/NiMH
by press "BATT TYPE" button.

4) Select the proper charging current 1A/2A/3A/4A by the slide switch.
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.
