Nicd/ Nimh Battery Charge Setup; Pb Battery Charge Setup; Lipo, Lilon, Life, Nicd, Nimh, Pb Battery Charge Processes; Charge Mode Per Battery Type - GRAUPNER S2003 Operating Instruction

- Cut-Temp : Cut-off temperature. Detected using an optional temperature sensor, a safety cut-off
temperature can be set to automatically terminate charging or discharging processes. This
termination can occur for battery temperatures exceeding a preset value.
: The maximum capacity setting is used to terminate a charge. The maximum capacity is
- Max Capacity
used to prevent the battery capacity from exceeding a preset percentage. Damaged, poorly
balanced, or improperly programmed batteries can be overcharged without this limitation.
- Safety Timer : The safety timer can be used to terminate a charge for charging times that exceed
this preset time period. This timer can be used to protect the battery from damage.
: The battery voltage in the store mode. This parameter is used to terminate a charge
- Store Volt
for voltages that reach a preset voltage value.
NiCd/ NiMH battery charge setup (Applied to CH1 and CH2)
- Current : Charge current. - Tapping the INC/DEC buttons can activate and edit this param-
eter. The default charge current is set to 1C (1 x capacity). The CH1 could be con-
figured from 0.1A to 20A (to be operated within 500W) and CH2 could be configured
from 0.1A to 3.0A (to be operated within 30W).
- Peak Sens : Delta-peak cut-off voltage. - This parameter is used to charge the NiCd/ NiMH
batteries. As the pack voltage peaks, the pack becomes hot and the pack voltage
drops off. This charger terminates the charging process using a Delta-peak cut-off.
The default parameter is 3mV/cell for the NiMH batteries and 7mV/cell for the NiCd
batteries.
- Tricke : Trickle charge current. - With NiCd and NiMH type batteries, a trickle charge pro-
cess is recommended after the main charge has completed, allowing the battery to
become fully charged and ready to be used. The recommended trickle charge current
is approximately 10% of the pack capacity (possible to set to a max of 500mA).
- Cut-Temp : Cut-off temperature. - Used with an optional temperature sensor, a safety cut-off
temperature value can be specified, allowing the charging or discharging processes to
automatically terminate for battery temperatures exceeding a preset value.
- Max Capacity: The maximum capacity setting is used to terminate charging processes for battery
capacities exceeding the selected percentage values. Damaged or improperly pro-
grammed batteries can be overcharged without a proper setting of this parameter.
- Safety Timer : The safety timer can be used to terminate the charging process for charging times
that exceed a preset time period. This timer is used to protect the batteries.
Pb battery charge setup (applied to CH1)
- Voltage : Maximum cell voltage. - CV (Constant Voltage)
- Current : Charge current. - Tapping the INC/DEC buttons can activate and edit the param-
eters. The default charge current is set to 1C (1 x capacity). This value can be
adjusted from 0.1 to 20 Amps, operating within the 500W limitation.
- Cut-Temp : Cut-off temperature. - Used with an optional temperature sensor, a safety cut-off
temperature can be set, allowing the charging or discharging processes to automatically
terminate at battery temperatures exceeding the preset temperature value.
- Max Capacity : The maximum capacity setting is used to terminate charging processes that result in
battery capacities exceeding a preset percentage value. Damaged, poorly balanced,
or improperly programmed batteries can be overcharged without this limitation.
- Safety Timer : The safety timer can be used to terminate the charging process for charging times
that exceed a preset time period. This timer is used to protect the batteries.

The programmed data are stored in the memory and used to charge the batteries. Tapping the Enter
button initiates the charging process. The balance connector verification, the charge mode verification,
the number of cells to be charged, and the delay time setup should be finished prior to the charging
process. For an improperly programmed setup, the charger will initiate a 5-second countdown without
any external controls.
Below picture shows the sequence of charging
LiPo, Lilon, LiFe, NiCd, NiMH, Pb battery charge process
The charger verifies the connection with
the balance board. This step is an auto-
matic process.
Charge mode selection
Both the charge mode and the delay time are programmed
parameters.
To activate, tap the box to become blue. Tap the DEC/INC
button to select the desired mode.
Charge modes are explained below
After a 5-second countdown, the charger initiates the
charging process. Tapping the Enter button
ates the charging process immediately.
Delay time setup
The Start Delay Time can be set at values ranging from
1-150 minutes.
The charger initiates the battery charging process after
the preset time has expired.

Charge mode per battery type

[ AUTOMATIC ]
NiCd/NiMH : This step is an automatic charging process, first determining the number of cells and then mon-
itoing the charge current. The charger calculates the internal resistance and charge current for every period
of time, automatically adjusting the charge current to ensure the delivery of the optimal charge current to your
pack. The PEAK SENS values (NiCd=7mV/cell, NiMH=4mV/cell) are applied automatically. The CUT-TEMP values
can be programmed.
