To help cool this particular unit, since the vents are located on the bottom and lower sides of the unit, I would just make sure there was plenty of cool air available to the vents. The heat will force draw the cool air in from the lower vents of the unit and up and out through any openings in the battery compartment or side of the unit. As for using the steel plate: The steel plate could warm up from radiated heat (not convection heating) and actually put warmer air into the unit over time and might not cool it as well as one might think. I've seen that in WiFi routers which can run VERY hot and you can fell the heat radiating even from the bottom vents, which warms up whatever it happens to sit on. I routinely put larger stand-offs on any test equipment that relies on cool air inlet vents on the base. In extreme cases, assuming there isn't already a fan inside the case, I even add a small fan (similar implementation as for "laptop computer coolers").

I am currently testing the newer device which is Lii-600 model ! The price is a bit higher than the "500s", but u get more features and the main advantage is the 250mA charging current for Ni-MH (AA, AAA) batteries so i can use the 0.1C current (250mA) for my 2500 mAh batteries for a 10h appropriate charge, in the 500S the current begins with 500 mA. Also the discharging current is more adjustable for more accurate measurement for the Ni-MH. If u need to charge 4 x Li-Ion (26650 cells @ 5500 mAh) with high ampere the Lii-600 can charge the 4 slots simultaneously for 3 ampere, however, I personally charge my Li-Ion cells with a current of 1 ampere, sometimes 2 in rush. The temperature measurement is very accurate, im testing it all the time for fun with my fingers on the cells to see if the sensor shows the truth, and YES the measurement is perfectly assigned to the channel. At first I thought about sticking small thermopads on metal sensors to increase the accuracy of the measurement but there is no need for that. Resistance measurement must be taken with a pinch of salt, but after a few tests on old cells, the test indicated 120-140 mOhm, and on new ones 38-45 mOhm, so as an indicator it shows very well. The TEST function can also be customized in advance to our current charge and discharge i guess it was : 250, 500, 750, can't reach for it now, device under test :) Also if 1 channel is finished with whatever mode was choosen, the slot can be replaced by a new cell for testing without crashing the other channel results, that was happening is some XTAR chargers for me... If u like more setting options get the Lii-600 ! You will not regret at all ! :)

CAUTION: I strongly advise NOT using the 12VDC car adapter from a car "cigarette lighter" as the risk of input voltages MUCH HIGHER than 12V is 100%. Use a *regulated* 12VDC adapter instead. The supplied 12VDC car adapter does NOT regulate the output in any way. It is just a direct wire (with a 3Amp fuse[1]) between the "cigarette lighter" socket and the Liito charger/analyzer. Whatever voltage is supplied at the cigarette lighter plug input, is seen at the adapter's coaxial output plug. If the cigarette lighter outlet is providing 14VDC (not uncommon), that is what will be provided to the Liito units when using this adapter. Also, car alternators routinely supply over 15VDC while charging the car battery while the car is running. Further, *starting a car can generate huge voltage spikes* over a hundred volts at the cigarette lighter socket[2]. Sensitive instrumentation circuitry can be damaged by the higher voltages. I am very concerned about using this adapter with any of the "12VDC" powered Liito units. There is even an Warning label on this car adapter that the *_INPUT_* to the adapter not exceed 12VDC. That explicitly confirms this advice. I hope the details provided here help explain the issue. -------------------------- [1] The fuse is NOT designed to protect the Liito charger/analyzer from damage. It is there ONLY to help prevent possible fire and/or damage to the car in the event of an overload. [2] A recent model car MAY have regulators on the cigarette lighter socket, however, it depends on the brand and the effectiveness can vary.

9:16 it's not the total time for the test, "4:30h" is the time for only discharging channel 2 (there is an indicator under "current" says :"DISCH", (for recharging need - 2:43h), so the total TEST time for channel 2 was 7h:13min (not including the first step which was a full charge to 4.2 V to begin the test) It can be easilly calculated if u have a 2000 mAh cell and you discharging it with 500mA current (2000 / 500 = 4hours of discharge), simple as that.

Nice review! Just want to ask if you can charge a device while charging a battery as well? Thanks

[@exgenica]

Do you mean use the USB port to "charge a device" while 1 or more cells are being charged in the charger? If that is the question, I would not do it because the 500s power management doesn't appear to be designed to handle continuous high current operation up to the specified 1000mA 5VDC USB output AND simultaneously charging li-ion cells with the higher current settings. It MAY be "OK" at lower mA values but it is a risk. From the User Manual I interpret it as *not advised* From the (badly translated) english version of the Lii-500s manual: _and only within battery inserted, there will be no USB output will be invalid_ However, there is no safety interlock to prevent user doing it (see note1) ==================================== note1: I did try this. The 500s allowed me to simultaneously charge ONE li-ion cell at 1000mA, while also using the USB port to charge a 5V "powerbank" (at about 500mA). However, I ran this for less than 30 seconds. Due to possible user error, I personally do not advise simultaneous use of the USB port and charging li-ion cell(s).

[@wellingtoncardoso7936]

I have Liitokala 500s and I didn't find any video in Portuguese detailing how it works. I have the following doubt: I performed the 18650mah battery test and presented the results: - Charging 1881mha - Download 0886mha. Which value should you consider, loading or unloading?

[@exgenica]

There are several situations that can affect these values relationship with each other. With a new, stored, or "out of shape" lithium cell, it can require multiple charge/discharge cycles before the capacity performance values become consistent. Also, results are more consistent when the charging and discharging currents are about equal and LOW. For example, charge AND discharge at 500mA (the 500s default values). Do not set charging at 1000mA and discharging at 250mA. Remember that the maximum discharge current possible with 500s is 500mA. Avoid charging at high currents like >=750mA. Remember that this is testing for a baseline...not operational performance. Testing for operational performance requires different parametric controls and values this unit *generally* cannot provide. Also, generally speaking for Li-Ion cells, charging at low currents yields higher reported capacities than when charging at high currents. Test only 1 lithium cell at a time. Testing multiple cells at the same time changes the algorithms the 500s uses to perform the testing on all the cells. Similarly, don't test 1 cell while charging or discharging lithium cells in the other sockets (which is allowed by the 500s). Doing that can affect test results. When the 500s has multiple lithium cells installed, it uses different algorithms to assign current and time spent charging or discharging within short periods. For example, when charging just 1 cell, ALL the time is spent charging the cell during a charge cycle. When there is another cell, the 500s may charge cell#1 for a short time, then charge cell#2 for a short time, then go back to cell#1. The "not charging" gaps like these while applying charging current can affect the apparent capacity of a cell. Similarly for discharging cells. Temperatures can affect charging capacity differently from discharging capacity (but usually OK if lithium cell remains at about room temperature. But, watch for lithium cell heating.) Edit to add: Also, I don't know how the 500s handles li-ion cells with the different types of protection or built-in charging circuits available. I suspect the 500s is probably not designed to charge/test/discharge that kind of cell, and at best one would get inconsistent results.

It should have no problem for a flat-top 20700 cell (~20mm diameter, ~70mm long. Button-top on some cells can add ~1mm to length). Later manufactured 500s versions have been confirmed by a few people to handle 21700 (in all channels) and even 32700 cells, so a flat-top 20700 that meets industry standards should fit fine in any channel position. Note: I've used flat-top 21700 cells in the 500s without problem (not button-tops). But I have not personally verified using any 32700 in the 500s. It seems to me that is probably just barely possible and because of its extremely large diameter (a fifty cent piece is about 31mm) 32700's would be limited to 1 or 2 at a time and only in channels 1 and/or 4.

On the high-end of capacity, the 500s has been working fine with 2x 5000mAh 21700's that I use with Ham Radio equipment. =========================== From My Feb2022 Review... _The (Lii-500s) unit I received easily handles 21700 size cells._ _With some "flat-top" cells (no top button) I have to interpose a small connector piece between the cell and the unit's positive connector to ensure contact with the positive end of the cell.

I don't like the automatic time out setting._ End of review extract. =========================== Note: for these tests I charged the 21700 cells using the LIi-500s and performed the discharge capacity testing using a trusted separate test instrument. My bench tests showed that when new, the achieved mAh capacity was actually about 4700 mAh (Id~500mA, Vt~3.0 using a separate Constant Current discharge tester. It's normal for even quality brand new Li-ion cells to charge to a bit less than their maximum specified capacity. In fact, it's often written into the detailed Li-ion cell manufacturer's specifications. These well-used cells still charge to about 4500mAh capacity, so things are going well. Edit to explain my deviating from a usual test parameter: I didn't use industry standard Id=0.2C in the discharge tests as I usually do. In these tests I was evaluating for the usual ~500mA load these cells had to handle when in my amateur radio equipment. Otherwise, Id=0.2C would normally be 1.0Amp (0.2 x 5000mAh Capacity), not the Id=500mA I used.
