iCharger Synchronous Balance Charger/Discharger 208B
Usually, the NiCd battery voltage will drop a little right after reaching full
charge. This is known as -△V. You can alter the iCharger‘s delta-peak
detection sensitivity.
Range: 1 – 20mV/Cell. (8mV/Cell, default)
When NiMH&NiCd batteries are deeply discharged or left unused for a long
time, they will produce a false -△V which stops charging early. You can
disable -△V testing to avoid this problem.
Range: 0 – 30min (0, default)
Battery upper temperature limit. The battery temperature can be monitored
with the attached temperature sensor. In order to protect the battery from
damage due to high temperatures the iCharger will stop charging or
discharging immediately if the temperature exceeds the cut-off setting.
Users can choose ℃ or
o F as the temperature unit
Range: 20 – 80℃(68 – 176 o F). o F = (9/5)×℃+32.
Charging time upper limit. The charging process will stop immediately if it
exceeds the set value.
Range: 1 – 999min
Capacity protection. The charging/discharging process will stop immediately
if the calculated charge input/drained exceeds the set value.
Range: 100 – 99900mAh
Input voltage protection lower limit. The charging/discharging process will
stop immediately if the input voltage falls below the set value.
Range: 4.50 – 30.00V (4.50V, default)
Current Range: 1.0A – 25.0A(25.0A, default)
Note: Current limit is not very accurate, which may be 20% difference, max.
Charge/Discharge power limit. The maximum charge/discharge power of
iCharger can be adjusted in order to limit internal temperature and to
protect the input current from over-loading . When the limit is set to AUTO
the iCharger can adjust the output charging power according to the input
capability.
CHG: 50 –350W and AUTO. DCHG: 5 –30W
Note: The maximum charge power capacity is also limited by input current.
The maximum input current of 208B is about 24A, and Wmax ≈ Imax * Vin
* 90%. (For example, when the input voltage is 11V, the maximum charge
power capacity ≈24Ч11Ч90％＝238W).
