LiitoKala Lii-100


DSC_3068 DSC_3069

LiitoKala has made a couple of analyzing charger, but this model cannot do any analyzing, it is a small universal charger that handles 3 types of LiIon and NiMH, it addition to this it can also work as a power bank.


The packaing was very simple, being just a plastic bag.


The pack contained the charger and a usb cable.


The charger is powered from micro usb and has a full size usb connector for power bank output.


The charger has two red leds to show selected current and four blue leds in a row to select voltage and show battery level.
The button has multiple functions:
When a battery is put into a powered charger, it can be used to select LiIon voltage (NiMH is selected automatic).
When charger is powered a long press (2 seconds) will change between 0.5A and 1A charge current.
A fast click when charging will show the selected battery type.
When used as a power bank a press on the button will turn the usb power on.

The charger uses the typical slider construction, it can handle batteries from 33mm to 70mm.

The charger can handle 70mm long batteries, inclusive flat top cells, this means most protected cells.

Measurements charger

  • LiIon and NiMH Batteries will be discharged with 0.1mA when power is off.
  • Charges LiIon batteries with 0.5mA when connected to power.
  • Charges NiMH batteries with 2.2mA when connected to power.
  • When battery is 0 volt the charger will charge with 3mA, this is enough to reset a protection.
  • From 0.25 volt on the battery the charger will reconize it and start charging.
  • Between 0.25 volt and 1.6 volt a battery is assumed to be NiMH.
  • Between 1.6 volt and 2.2 volt the charger will charge with less than 2mA and not allow selection of battery type.
  • Above 2.2 volt a battery is assumed to be LiIon.
  • Charger will not restart if battery voltage drops.
  • Charger will restart charging after power loss, or battery insertion.

Charging 4.20 volt LiIon


The charger has a fine CC/CV voltage charge curve, it starts reducing current a bit early, due to voltage constrains, this will give slightly longer charge time.



No surprise on these two cells.


Reducing the charge current to 0.5A works fine, except the termination current is not reduced (Cells will miss the last few percent of the charge).


With this older cell the current reduction starts very early as expected.



Good charging on these smaller cell, again the higher termination current means a few percent loss in capacity.


Adding a resistor in series with the usb power supply to simulate a long cable or weak supply did not prevent the charger from doing a good job, but it needed some more time.


M1: 32,4°C, M2: 31,4°C, M3: 40,0°C, HS1: 48,8°C


The charger needs some time to start up, this is because it is waiting for voltage selection.


There is no problem with changing current while charging.

Charging 4.35 volt LiIon


The 4.35 volt charge works as expected.

Charging 3.60 volt LiIon



Both LiFePO4 cells is charged fine, but the voltage is a bit high (This is not a big problem with LiFePO4).

Charging NiMH


This is a fine NiMH charge with voltage termination and no trickle charge.
When using voltage termination without a top-off charge the batteries will be slightly below full capacity.


Using 0.5A charge current is also stopped on voltage termination.


On this cell it looks like a voltage termination.


Here it is -dv/dt termination.


My new powerex cell is stopped on -dv/dt.


The AAA cell is stopped on voltage.


Fast detection of a full cell, this is voltage termination.


M1: 35,4°C, M2: 34,2°C, M3: 41,9°C, HS1: 53,5°C


The charger is also slow to start with NiMH, but it is not possible to select any other battery type.


There is no problem with changing current while charging. The charger uses the typical pulsing, where it can measure voltage with current off.

Power bank

  • USB output will turn off after 10 seconds with less than 65mA load.
  • When input power is applied, usb output will be off.
  • Mode button can be used to turn usb output on.
  • USB output is coded as usb charger (DCP).


USB output can deliver 1.3A before it starts dropping, the overload protection first kicks in at 2A.


Running with 0.5A load looks very good.


1A output also looks very good.


The noise is fairly good at 0.5A load with 20mV rms and 170mVpp


At 1A the noise increases, but is still acceptable with: 38mV rms and 310mVpp


It looks like this model often is a bit high in charge voltage, but within allowable tolerances. I did not see any problems real with it.

This makes it a good charger for all supported batteries and also a good power bank
