Hello,
Here are my experiences with the LiitoKala Lii-700.
The original is in german language, I used an translator, if something looks not understandable please ask me
If I use - or + only in begin of a line this forum sets it to a countmark which not shows if I meant minus or plus, so I start with a / and then the + or -
Features:
Charging: 500/1000/1500/2000/2500/3000 mA, with both Li-ion and NiMH batteries
Discharging: 250/500/1000/1500/2000 mA, with both Li-ion and NiMH batteries
Test: Charging current is selectable; the discharge current is determined by the charging current. Charge → Discharge → Charge
Repair: Charge at 500mA (which seems relatively high for this mode)
D-cells can also be used, but this isn’t mentioned in the specifications
Li-ion up to 32700
Resistance measurement with 4 leads (external)
Haptics:
+/- Mediocre build quality, spring in one slot is stiff
+/- Button response could be better (sometimes a longer press is required)
+/- Clearly audible fan when discharging, for example, 2x Li-ion at 1A each (fan isn’t permanently on)
/- Small cells have contact issues
Operation:
/+ Overall, simple and good operation
/+ Modes can be switched at any time by holding the Mode button
Display/Status Indicators:
/+ Real-time display of charging current
/+ The most important data for each slot is displayed simultaneously
/- No status LED for individual slots; only one slot can be displayed at a time
Charging
/+ Wide range of charging currents
+/- Current increments could be finer
+/- Generally mediocre NiMH charger with termination issues
/- Sometimes very early termination with NiMH AAA batteries
Discharging:
/+ Wide range of discharge currents, high discharge power
/- Due to the discharge measurement method, significantly lower capacities are displayed for batteries in less than ideal condition.
/- Fan is clearly audible and sometimes even switches on when discharging a Li-ion battery at 1A
The display is very easy to read and dims one minute after the last button press. However, a longer press of a slot button allows you to keep it permanently at full brightness.
Rather unsuitable for NiMH batteries, especially AAA batteries. Some very early termination and contact problems occur. It performs significantly better with AA batteries, for whatever reason.
For Li-ion batteries, however, it’s a very good charger and, thanks to the available currents, both charging and discharging are fast. However, I would never set all four slots to discharge Li-ion batteries at 1A per slot or more, despite the fan.
I don’t know if the fan also activates when charging at full power; I don’t have suitable batteries for such a test.
Aside from NiMH charging, the biggest drawback for me is the display. While all relevant values are shown, they are only displayed for one slot at a time, requiring constant switching. The predecessor, the smaller Lii-600 model, has at least one status LED per slot, which I consider a significant advantage.
I can’t comment on the accuracy of the external resistance measurement.
Conclusion: Even though the Lii-600’s discharge power is significantly lower than the Lii-700’s, and it also lacks external 4-wire resistance measurement, the Lii-600 is the better product in my opinion.
A drawback of both chargers is their (lack of) availability in German online shops.
