Green Digital Power-tech G10-XXL User manual

CAUTION
1. SAVE THIS INSTRUCTIONS- This manual contains important safety and
operating instructions for the G10-XXL battery charger.
Please read the caution ofbatteries or devices you want to charge firstly!
2. When charging, batteries can emit explosive gases, therefore it is essential to
prevent flames and sparks. The charger is designed for charging
Li-Ion/LiFePo4 batteries from 3.2V to 14.8V. Do not use for any other
purpose.
3. Always provide good ventilation when charging.
4. Use of an attachment not recommended or sold by Green-Digital Power-tech
may result in a risk of fire, electric shock or serious injury to persons.
5. To reduce risk of damage to electric plug and cord, pull by the plug rather than
by the cord when disconnecting charger.
6. An extension cord should not be used unless absolutely necessary. Use of an
improper extension cord could result in a risk of fire and electric shock. If
extension cord must be used, make sure that: a) Pins on plug of extension
cord are the same number, size and shape as those of plug on charger; b)
Extension cord is properly wired and in good electrical condition; and c) Wire
size is large enough for ac ampere rating as specified in “technical data”.
7. Do not operate charger with a damaged cord or plug-return the charger to the
place where purchased.
8. Never operate the charger if it has received a sharp blow, been dropped or
otherwise damaged in any way; take is to a qualified serviceman.
9. Do not disassemble the charger; take it to a qualified serviceman when
service or repair is required. Incorrect reassembly may result in a risk of
electrical shock or fire.
10. To reduce risk of electric shock, unplug charger from AC outlet before
attempting any maintenance or cleaning. Turning off controls will not reduce
the risk.

Brief Introduction
G10-XXL is a main member of digital-chargers from Green Digital
Power-tech Co., Ltd. It represents today’s new technology for 3.2V(1s)
~14.8V(4s) Li-Ion, Polymer or Li-Fe battery pack charging. G10-XXL
programmed 2 auto stages (Im-Um) charging process，It is designed for
2~8Ah Li-Ion/Polymer/LiFePo4 battery pack. When the battery is connected
properly, “Im” will give bulk constant current charging, until voltage reach CV
point. Then, “Um” stage is followed, the output voltage is limited on 4.2V/per
cell(3.6v for LiFePo4) , until the charge current declined to 0.1A. At this stage,
the battery is charged completely and the charger will cut off output automatic.
Further, G10 can display the charging process, indicate the battery
capacity from 50% to 100% timely. This is helpful for user.
For more safety, G10 will inter protection mode when the battery polarity
reversed our the output connectors shorted.

How to use:
1. Connect theAC cord tothe socket, The “power” lamp will light on RED.
2. Connect positive charger clip (red) to positive battery terminal, the black clip
to negative. (You can use other dc plugs to connect battery), the
“50%~100%” lamps will light on flowing. If the battery polarity reversed or
output shorted, 3 lamps willflashing, please check the setup.
3. Depend on the charged capacity, 50%~100% lamps will lights up solid
sequence, until the battery is fully charged. Then you can power off the
charger and disconnect the battery or you can charge a new battery if you
need.
The table shows the durationof 80% state charged for anempty battery.
