manual completely and attentively before using this product, as it covers a wide range of information on
operating and safety.
G-Force G3 Charger is an economic, high quality 100-240V AC balance charger, designed for charging
LiPo and LiFe batteries from 1 to 3 cells in balance mode. The circuit power is 15W and max charge
current can reach to 1.5A. There are three kinds of charge current 0.5A/1A/1.5A that can be selected.
You could select the proper charge current according to your battery capacity.
INTRODUCTION
CHARGE PROCEDURES
G-Force G3 comes with the built in power supply. You can connect the AC power cord to the AC socket
(100-240V AC) directly.
