CARSON EXPERT CHARGER 3
NR. 50 060 6045
OPERATION INSTRUCTION
PRODUCT DESCRIPTION
The EXPERT CHARGER 3 has been developed to charge
LiPo R/C battery packs of 1 to 3 cells or
LiFe R/C battery packs of 1 to 3 cells or
NiCd/NiMH R/C battery packs of 4 to 8 cells.
There are 3 charging methods:
• Automatic fast charge with a charging current of 1A,
2A or 4A, with delta V control (for NiCd and NiMH).
• Slow charge of transmitter and receiver battery with a
charging current of 150mA (only for NiCd/NiMH).
• Automatic fast charge with pre-defined discharge of
NiCd/NiMH R/C battery packs to reduce the memory
effect and to maintain the power of the battery pack. It is
recommended to discharge the battery pack every ten
charging cycles.
This charger can be connected to the 230V 50Hz mains
socket OR to the 12V DC vehicle cigarette lighter socket.
FAST CHARGE with 1A, 2A or 4A charging
current
1. Connect the charger to the 230V 50Hz mains socket OR
to the 12V DC cigarette lighter socket. The yellow LED
"INPUT" should light.
2. Select the "LiPo" or "LiFe" or "NiCd/NiMH" slide switch
according to the battery cell type.
-LiPo for 1 to 3 cells Lithium Polymer battery
-LiFe for 1 to 3 cells Lithium Iron battery
-NiCd/NiMH for 4 to 8 cells Nickel Cadmium or Nickel
Metal Hydride battery.
3. Select the 1A, 2A or 4A slide switch according to the
required charging current:
Current
Capacity NiCd/NiMH
1A
500 to 800mAh
2A
900mAh to 1,3Ah
4A
>1.3Ah
Please pay attention to the maximum charging current
allowed by the battery manufacturer.
For LiPo batteries the values listed below are valid:
Voltage level 3.7V per cell
Maximum charge voltage 4.2V per cell
For LiFe: Voltage level 3,3V per cell
Maximum charge voltage 3,7V per cell
Capacity LiPo/LiFe
According to the
recommendation of the
battery manufacturer
4.
Connect the R/C battery pack with the correct polarity to
the 4mm charging sockets "OUTPUT" at the front of the
charger by using an adaptor cable (not included).
5. Make sure the red LED "FAST" lights.
6. When charging 2-3 cells LiPo/LiFe battery pack,
connect the balancing socket of the battery pack to the
built-in balancer of the charger.
7. After termination of the fast charging process the red
LED goes out. A NiCd or NiMH battery pack can be left
attached to the charger for several hours without any
damage. To terminate charging remove the battery pack
from the charger.
FAST CHARGING with pre-defined discharge
(For NiCd or NiMH R/C packs with 6 and 7 cells)
1. Proceed as described in "FAST CHARGE" step1 to 4.
2. Press the button "DISCHARGE/CHARGE". The pre-
defined discharge of the battery pack connected is now
started. By pressing the button a second time the
charger can be manually switched back to the charging
process.
3. During discharge the green LED "DISCHARGE" lights.
Attention: The discharging time depends on the
charging status and the capacity of the connected
battery pack and can take several hours.
CHARGING OF TRANSMITTER AND
RECEIVER BATTERIES
1. Connect the charger to the 230V 50Hz mains socket OR
to the 12V DC vehicle cigarette lighter socket.
2. Connect the battery pack with the correct polarity to the
4mm charging sockets TRANSMITTER "TX" or
RECEIVER "RX" at the front of the charger by using an
adaptor cable (not included).
3. Check whether the corresponding red LED lights to
make sure the charging process has been started.
4. To terminate charging remove the battery pack from the
charging cable.
The slow charging time can be determined according to
the following formula:
Charging time (hours) = battery pack capacity (mAh) x 1.4
Example: 1500mAh x 1.4 = 14 hours
