OPUS BT – C3100 Digital Intelligent 4 Slots LCD Battery Charger For Li-ion NiCd NiMH AA AAA 10440 18650 Rechargeable Batteries
This charger is a analyzing LiIon and NiMH charger, this means the charger can both charge and discharge while measuring. The total number of function is large and this means the technical section in this review is very large.
When the charger is turned on, it displays test where all the text can be seen.
Description:
Item type:Battery Charger
Voltage update rate is the 30s instead of 60s.
Charging voltage is regulated to 4.7V instead of 5.0V, thus loading on power adapter when batteries are flat is less. 5.0V charging voltage has a problem in regulating the correct current level due to this overloading current on the power adapter, which leads to Panasonic brand Li-ion batteries showed wrong charging capacity value ( + 25 percent ). With 4.7V charging voltage, the load on power adapter is greatly reduced and thus can make all types of batteries charged properly.
4.35V charging time can be very long because charging current is regulated in entering the CV stage at 4.12V, which is same as 4.2V type. Now, 4.35V charging algorithm is changed to 4.27V.
Better safety feature: PCB temperature was used to in controlling fan on / off only with 2.0V, now this function is enhanced so that temperature is monitored for entering thermal shutdown mode when an excessive high temperature is reached. It is especially helpful when the fan is not running and which can lead to plastic meltdown happening.
New fan cover provides better protection for the cooling fan.
