Operation Instruction
1
Plug into AC socket, LED light turns Green.
2
Plug BEC connector and attached temp sensor firmly to the battery before
connect the battery to the charger
3
Connect battery to the charger, LED light turns RED, which means battery is
in charge.
4
LED turns Green again, which means battery is fully charged.
5
Unplug the battery.
6
Unplug the charger from AC socket
Caution:
•In door use only, avoid water.
•Do not charge non-rechargeable batteries
•Only charge Nimh or Nicd batteries with 2Ah ≤ capacity ≤14Ah.
•Only charge NiMH / NiCd battery pack with voltage between 19.2V-24V
(16 -20 cells). Don't use the charger for battery with lower or higher voltage
which may cause battery to explode.
•Do not open the case to prevent from electric shock.
•Unplug the charger from AC outlet while not use.
•Always place the charger in well-ventilated, dry environment and indoor use
only
•The charger’s temperature sensor connector (BEC male connector) must be
attached firmly to battery pack. If you don't connect the temperature sensor
to battery pack, we are NOT liable for over charging the pack and damage
the pack.
