CONNECTION DIAGRAM

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.

INTRODUCTION

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.

Insert the AC power cord into the charger.
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.
Select  the  battery  type  LiPo/LiFe/LiHV/NiMH 
by press “BATT TYPE” button.

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

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. 
The charger starts charging. The charge status LED will glow to indicate charging is in progress.

When the battery is fully charged, the charge status LED will glow constant green. Unplug the battery 
from the charger and the charge status LED will flash green which indicates the charger is ready to 
charge another battery.

Charging LiPo/LiFe/LiHV Battery

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.

EXPLANATION OF LED STATUS

This diagram shows the correct 
way to connect your battery to the 
e450 charger while charging in 
balance mode. Failure to connect 
as shown in this diagram will 
damage this charger.

CAUTION:

6)

Charging NiMH Battery

Connect the battery main charge lead to battery socket which is in the front side of the charger.
Press and hold “BATT TYPE” button for 2 seconds to start charging. The charge status LED will glow 
to indicate charging is in progress.

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. 

WARNING:

When the battery is fully charged, the charge status LED will glow constant green. Unplug the battery 
from the charger and the charge status LED will flash green which indicates the charger is ready to 
charge another battery.
