1. SAVE THIS INSTRUCTIONS- This manual contains important safety and
operating instructions for the L500CM-XX 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 specified
Li-Ion or LiFePo4 batteries. Do notuse 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

Brief Introduction
L500CM-xx family is a main member of digital-chargers from Green Digital
Power-tech Co., Ltd. It is designed for 24V~48V (7S~16S) Li-Ion or LiFePO4
battery pack charging. L500CM-xx programmed 3 auto stages ( CC-CV-Cutoff)
charging process. “CC” means constant current charging, the charge current is
not changed during this stage. “CV” stage is followed “CC”, the output voltage
is limited on a specified value and not changed at this stage, until the battery is
charged completely and then charger will cut off output automatic.
For more safety, L500CM-xx has more protections function, such as
when the battery polarity reversed protection or the output connectors
shorted protection.

How to use:
1) Connect the AC cord to the socket, The “Power” LED lamp will light on
and “Charging” LED lamp will be extinguished.
2) Connect DC plug with your matched Li-ion or LiFePO4 battery-pack,
then the “Charging” LED lamp will turn to solid “RED” color and the
charging process is working correctly. If the battery polarity reversed or
output shorted, this LED lamp will display “RED flashing”, please
check and remove errors connected.
3) When the battery full charged, the “Charging LED” lamp will turn to solid
“GREED” color. That means your battery is full charged and you can
disconnect DC plug and AC power line.
Charging LED Power LED
