Test/review of Charger LiitoKala LiitoKala Lii-500S

Charger LiitoKala LiitoKala Lii-500S
DSC_8214
DSC_8215 DSC_8216
This is a advanced 4 channel charger for LiIon and NiMH with multiple current settings and USB output.

DSC_8130
It arrived in a yellow cardboard box with lots of specifications on it.
DSC_8210
The box contained the charger, power adapter, and a instruction sheet.
The supplied power adapter is a universal voltage (100-240VAC 50/60Hz) with 12V 3A output branded LiitoKala.
DSC_8217
The charger has a DC power input for the mains adapter and a 1A usb output.
DSC_8218
The user interface is 6 touch buttons and a display. The four top buttons is used to select a specific slot, when none of them has been pressed MODE and CURRENT works on all slots simultaneously.
The two bottom buttons is used to select mode (Charge, discharge, test) and current (500, 700, 1000mA, 2000mA). The current is charge current, discharge current will be either 250mA or 500mA.
Once charger is working it is not possible to change settings.
DSC_9614
During power on the charger will turn all segments in the display on and the leds in the top buttons, there is both a red and a green led.
As can be seen the display will only show data for one channel at a time.
DSC_9612
Without batteries in the charger it will show null, until the display turns off.
DSC_9615
Charging two batteries. This can be seen on the two red leds. The display shows information for slot #2.
DSC_8219 DSC_8221
The slots uses the classical slider construction and it works fine.
The slots can work from 32 mm to 74mm. This means that it will handle all protected 18650, 21700 and 26650 cells.
DSC_8220
The 2A slots are marked.

The charger is slow to start, because it waits for user input.
Charge NiMH
LiitoKala%20Lii-500S%201A%20%28eneloop%29%20%231
The charger uses a -dv/dt termination, here it needs about 20 minutes to detect it, this means the battery gets fairly hot at the end. Then it continues with a trickle charge of about 17mA

The same slow startup as with LiIon. As usually the charger turns current off to measure voltage.

This is a combination of charger, discharge and then charging again, show the result from the discharge.
LiitoKala%20Lii-500S%200.5A%20test%20%28SA18650-33%29%20%231

Display shows 3257mAh 6:30
LiitoKala%20Lii-500S%201A%20test%20%28eneloop%29%20%231
The NiMH is faster the to test, but still takes a lot of time (9 hours).
Display shows 1977mAh 3:57
USB output

  • When not powered the charger will drain LiIon batteries with 2mA (No USB symbol on display)
  • When display is on the charger will drain LiIon batteries with 26mA (Total for all loaded batteries)
  • When display is off, but USB output is on the charger will drain LiIon batteries with 13mA (Total for all loaded batteries)
  • MODE button will turn display on
  • USB output is coded as Apple 1A
  • When power is connected, USB output is forced off.
  • When the load drops below 70mA the output will turn off in 20 seconds.

LiitoKala%20Lii-500S%20230V%20load%20sweep
The USB output can deliver 1.1A, this is fine for a 1A USB charger, but not that much current for a modern smartphone or tablet.
LiitoKala%20Lii-500S%20120V%20load%20sweep
LiitoKala%20Lii-500S%20charging%20230V%20load%20sweep
The USB output also works with full power while charging 4 LiIon batteries.
LiitoKala%20Lii-500S%20230V%20load%20test
There is no problem running the USB output at 1A for one hour.
The temperature photos below are taken between 30 minutes and 60 minutes into the one hour test.
Temp7029
HS1: 51.6°C
Temp7030
HS1: 48.3°C
Temp7031
HS1: 42.1°C
10ohm
There is 42mV rms and 1403mVpp noise. This is very good values.
5ohm
There is 40mV rms and 1324mVpp noise. The high peak level is probably common mode noise from the power supply.
Testing the power supply with 2830 volt worked fine, but it failed 4242 volt between mains and low volt side, this makes it unsafe in 230V countries.
Conclusion
The charger works, LiIon charge voltage is slightly on the high side, it is not perfect at terminating NiMH and USB output works fine at 1A. The temperature when discharging batteries is acceptable. The displayed capacity values are a bit on the high side.
The failed high voltage test is bad, buying another power supply could fix it.

Thanks for the review. They are very helpful.

With the Failed High Voltage test and the Inability to Discharge at 1amp[1000mAh], I am happy to stick with my Opus BT-C3100 2.2. Big Smile

Will it be safe to use the old Lii-500 power supply, if not charging cells with the 2A option?

It is LiIon charging you have to be careful with. My guess is that a total of 4A LiIon charge current will be safe with a 2A plug pack.

Nice, then I will replace the new power supply with the old Lii-500 one, and use the new charger as usual.

Thank you for the review. I have a Lii-500S, and it seems to be terminating charging of my Li-ion cells at 4.2 volts and otherwise working fine. I’ve also charged quite a few Eneloop and Fujistsu NiMH cells, which have not felt warm to the touch at termination of charging.

I’ve used this charger maybe 15 times in 230 volt with the original power adaptor. Can this have damaged the charger, in a way there could now be a weakness inside that may once escalate into something serious danger? And even if I now start to use the old Lii-500 power supply?

Don’t see why since the power supply is a universal one (100-240VAC 50/60Hz) and the charger itself only sees 12 volts.

Most likely not. The risk with a failed high voltage test is not the charger, but anyone touching the metal on the charger, but the high voltage test/requirement includes a lot of safety compare to normal domestic power. If you lives near some large factories or have a lot of lighting strikes in the area the risk is greater.

In 2020 I would say that this is not a good charger either for Lion or Nimh.

With so many good choices out there we have to start to be more critical of newer devices and this one based on HJK review should fall under the no buy category.

HJK work is important because most of us do not have equipment to see what the charger is actually doing.
In the end these chargers end up charging the batteries and they tell us what they charged but without the equipment we dont know if it handled the cells properly and/or actually charged the cells correctly.

Thanks for the review HKJ.
Very good work. Smile
I have this charger. Hhmm. But the good thing, i have another charger to use Xtar Sv2 Rocket Smile
Is there anyone who can recommend a power supply for the Liitokala 500S charger with eu plug.
Thanks in advance.

It’s probably a ‘standard size’ plug, at least the one on the older Lii-500 is. I’ve found 3-5A/12v PS in local computer/electronics recycle stores for like $2-3. Work great. Many of my chargers are now powered by these ‘upgrades’.
Just take the charger with you to check for sure and glasses if you need them to read the fine print for output.

I agree with @hammerJoe. There would seem to be better chargers available. It’s not awful, but after reading HKJ review I wouldn’t buy it.

Thanks for the answer flydiver. Wink
I have your solution in my mind.
The solution for me was easier than I thought. Uses the Xtar power supply. The plug fits nicely and even if it only gives 2A it will work fine. I don’t charge the batteries so hard.

@HKJ
Thanks for the review!
The display backlight turns off after 30 seconds but when you press one of the channel buttons for a few seconds it will stay on.
Perhaps you could add that to the list.

Thank You HKJ for that review. That was very deep/detailed, clear presentation.
I was going to buy this charger later this year.
But now I will get another Opus BT-C3100 2.2 instead. Thumbs Up

You mention that there are better alternatives – would you mind giving an example of other chargers that have the same functionality – can charge 21700 Li-ion, as well as NiMH and act as a power bank.
