Dramatically fantastic, excellent explanation on liitokala capacity testing, I’ve bought liitokala lii-E260 for only testing capacity and internal resistance. Greetings from Saudi Arabia.
The Video is well presented, edited and informative. Just beware, the batteries get heated up from my experience due to ambient heat produced by charger. Tested 6 chargers, all batteries got quite hot.
Yup! thanks for the advise. i had all those experiences during my test. i bin all of the heaters especially those with very high internal resistance. they won't last anyway with that kind of condition.
in the NOR TEST when the current selected is 500ma or less, the discharge current is 250ma.. when the current selected is 700ma or more, the discharge is 500ma (according to the manual)!!
Haven’t finished watching the video yet but I can tell already THIS IS EXACTLY WHAT I WAS LOOKING FOR, someone who knew what they are talking about when explaining this exact charger that I am interested in buying for this exact purpose of testing actual battery capacity. VERY WELL EXPLAINED👍. But I don’t think 21700’s will fit or will it?? Either way it seems like a very nice charger for $27 (US) on Amazon. My Nitecore was the same price but does not have as good features although it does accommodate 21700 except for the protected type. Thank You!!
1000mA setting is for charging current. At 700/1000 settings, in test mode (where discharging is applied), discharging current is set to 500mA! Read manual and check by yourself.
love the explanations, thanks! Question: 1) Is the internal capacity number accurate (I know some chargers are not)? 2) for 18650, if the Internal resistance goes above what number, does that mean the cell is not great to use?
here are my answer to your questions: i'm not really sure if the internal resistance value displayed are accurate because i don't have IR tester to compare. but one thing i've noticed with this tester is the max IR stops at 125mR so it doesn't give you the actual internal resistance value. for sorting purposes (w/c i think is still good for use), i only use cells with 50mR and below because i had an experience using 100mR or more and the cell doesn't that long.

Lii-PD4 is just a charger while Lii-500 can both charge and do capacity test of your cell. Lii-Pd4's interface are better though and can charge even Lifepo4's that Lii-500 doesn't have.
Yes, each slot is capable of a 1000mA charging current. you just need to set the charging paramaters of the current to "1000mA" and mode to "charging".
@@taunteratwill1787 yes, how did you count it? :) You know that the charger is powered by a 12V 2A power supply, which gives 24W power, and the cell are charged 4.2V 1A, in simplified terms, the charging voltage of each cell is 5V and the current consumed is 1A, so 4 batteries charged simultaneously take 5V and 4A from the charger, which gives something about 20W

well its not unnecessary as what you think. the most important function of Liitokala Lii-500 is the cell capacity test . its not enough that you just charge your battery in full without knowing if the capacity is right for whatever you intend to use it. in my case, for my powerwall, i test each and every cell and for me to select the right amount of capacity that i need for my powerwall.
@@philippinediypowerwall3852 Not everybody builds power wall I think you know that by now right? If I only need to power headlights, torches, cameras, remotes, shavers etc, why would I need to know how much capacity my 18650 got? it's got 3400mAh and when it starts holding less charge, I will know it's time to toss it. I mean what would knowing it's actual capacity do for me? would that bring a 1400mAh cell back to its initial 3400mAh? You and I know quite well this is just a way a justifying consumerism. This expensive chargers don't mean shit. I will never buy them again.

@@kay19833 well that's your call. i'm using Liitokala Lii-500 to test cells that i need for my powerwall. all the cells i'm testing is 2nd hand by the way, that's why i need to know the actual tested capacity of each cell so that i can select the right one for my need (2500 mah & up, preferred plus below 50 ohms internal resistance). that cells will still be good in service for probably 3 more years on my powerwall. if you have 3400 mah cell and its brand new, then all you need is a charger. i'm not forcing you to buy anything like Littokala, because we both have different purpose for the cell's use.
@@kay19833 it may not be useful for you at this point (aside from charging) if your cells are still brand new. but definitely, in the long run, you can check the capacity as as time goes by with continuous use of the cell. this can help you decide whether to bin the cell or can still use it.
Sorry, but your test is faulted... you not discharging at 1 Amp ... in one hour 1000mah should be shown on charger ... u only got about 500mah.... thats charging current setting u toying with. i think discharge is limited to 500mah.
how is it incorrect? you are counting the discahrge capacity by hour. didn't you notice my setting? NORTEST is a discharge capacity test, and the discharge current is set at 1000mA. you better study setting parameters of this kind of tester before making comments.
The user interface is 6 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, fast discharger, normal discharge) and current (300, 500, 700, 1000mA). The current is charge current, discharge current will be either 250mA (300/500 selected) or 500mA (700/1000 selected).
i am good in mathematics ... saw your error by calculations as i charge using imax b6 and it has schooled me well about capacities. i just bought 6 litokala i500 ... using it 1 day now and am convinced, 500mah max discharge... i have the mathematics in front of me...
No reason to be writing in rude condescending tone "you better study setting parameters of this kind of tester before making comments" .... i gave a straight forward critique ... sorry if you took it as insult.
i just bought 4 of these and they all measure very wrong my 1600mah which is two years old is measured to 18xxmah by 1amp discharge do not buy this shit
well i haven't seen any tester that could say that it is accurate enough in capacity test. even opus (more popular than Littokala) has accuracy issue too.
Most testers are accurate but they vary in their respective process parameters such as minimum discharge voltages. Currently testing lithokala vs discharge module against my imax b6 as benchmark. the litokala reading around 15% more capacity but apparently its cutoff voltage is 2,8V vs 3.0V for imax b6. So i deduce the both pretty accurate cos further 0.2v deeper discharge will yeild few 100 more mah. Another factor is, on imax i can let the cell stand and cool off before discharge, whilst lithokala discharges hot cell immediately after charged. This will give higher mah. So final word of advise, it matters not which good quality charger you use for discharge, but you should use same one to test each battery thats going into a pack so the testing parameters are same.
Don't buy the LiitoKala Lii 500 it's a piece of garbage... there is no over voltage protection circuit for each charging slot, so if you have a defective battery that attempts to draw more current than is allowed (because it is defective) it will damage the voltage regulator inside the unit and render the entire unit useless (each channel isn't isolated) I've had two chargers where this issue has happened to me.. or some other component inside the motherboard gets damaged because it has no protection circuit... spend the $50 and just get an OPUS charger.... unless you like seeing your charger go up in smoke... or your money.
As you can tell by your test, discharge is 500ma when the charge current is set to 1000. You better study setting parameters of this kind of tester before making videos!
that's the highest setting (1000ma) that u can do with the tester. i have observed that too with several test that it really does not give the right amount of current for the test. studying the setting parameters is just easy but u can't control what this tester can give with the results.

Most if see video only do discharge at 1A
Discharge current is only 500ma
Yup, just half of the current settings
Why test only discharge at 1a?? Can discharge 5-8a? if let say build battery pack 36v for ebike and it Will draw 80-500watt!
Shame it can't show all 4 slots at the same time like the Opus V2. I don't want to be clicking through the buttons.
bad battery recovery possible??
I noticed that the cell internal resistance changed..Why was this?

you can also try opus bt-3100
I have read on other reviews when you set current at 1000mA the discharge test runs at 500mA. The call then charges at 1000mA. Can you confirm this?
call=cell
@@kurtwendorf4747 yes, i have observed that too during the test. the tester only give half of the set current for the test. it shows in the running time how much capacity u can get per hour.
how is it 3 hrs into the test and you only got 1500mah, but it's discharging at 1000ma
The device indicates 1 amp but whatever you do it will not discharge above 500 ma.
does anyone know the difference between 500 and 500s?
How is possible with a discharging current of 1000ma in 4,75 hours test the cell only drains 2268 mah?
Only discharges at 500ma on 100ma setting.
you're right. i have observed that too during the capacity test. the math says that so.
Internal resistance is changed at 3:19 did you change cell ?

hi ... dont take this chargers ir values as accurate ... they are way off and fluctuate much ... just use a fixed load using imax b6 or discharger module and do the maths.
At 2:19 how can you be testing for 1 hour at 1000mA and only gotten 487mAh ?
i have observed that too. even when the current setting for the test is 1000ma i only get half of that in the test result.
Because it's discharging at 500mA and starts charging at 1000mA after it's discharges the cell.
What is the normal cell temperature during the process?
well the tester doesn't have temp display or i even don't have thermal imaging gadget to know what temp is normal or not. the cell normally gets warm during the test but when its too hot to handle with your bare hand, it usually is a heater and not use it on my powerwall. but based on the forum DIY Powerwall, normally they only use below 30 degree, and above 35 degree they recycle the cell.
