This is what I don’t understand. Why would anyone purchase the Lii-100? I bought one. It was reputed to overcharge batteries but I said “Aw, what the hell, I’ll check it out”. It did indeed overcharge my battery and I threw it in the dumpster. I know there is a reason behind the thinking here but I’m missing it. Why trust cells to a charger that costs a fraction of the cost of the cell itself and charges them improperly? Not trying to be a smart-ass—I just would like to know.

Only some of those chargers overcharged, not sure which batch it was. I checked all of my Liitokala chargers and none of them overcharged – but I was late to the party back when they came into fashion.

They are lightweight, cheap, easy to use, have multi-chemistry, multi-sizes and also a powerbank feature. It is the ideal travel charger, a great gift or stocking filler, amazing in the glove box, or fit in the go-bag/backpack.

Our BLF modification of this charger on here (forgot who/where it was) added the missing voltmeter and it was a popular mod. But even without the voltmeter the charger displays the charge status when you put a battery in.

Whenever somebody brings up the overcharging issue, it was immediately dismissed as non-issue because easy, simple resistor mod fixes it.

But sorry to burst the bubble, it does NOT display actual flowing current, it only shows the selected current (0.50A or 1.00A).
Real-time voltage is shown.

Well fellows, this demonstrates either their obvious lack of language understanding and/or their dishonesty. And I do not mean to judge.

I'll try to be as clear as possible. This has to do with component tolerances, target consumer market's awareness level and related belief systems (more is better maybe?). Charging voltage is determined via a resistor divider, if this divider is made with 1% tolerance resistors it is quite likely that about half of chargers will “overcharge” to some extent. Since termination current value also plays a role, causing a slight additional drop in charging voltage, it is likely that the default maximum charging voltage is by default set slightly high to compensate.

So sorry Bushmaster, what you're asking for is still only possible for the DIY crowd. Fix your Lii-100 units, here's the information: How to fix high charge voltage in Liitokala Lii-100 and how to make lower charge currents

By the way, a 1% variation in final charging voltage is no big deal for quality cells. If you really want to boost your cells' lifespan aim for higher reductions, the less voltage the better but only down to 14/15th (3.92/4.2) of maximum value. In a Samsung INR18650-35E datasheet a reduction in charging voltage down to 4V is mentioned for UPS applications, see that also.

I was looking forward to getting three or four of these little chargers because of the display, but now that I know that it does not display the actual voltage of the cell I can save a few bucks and forget about it.

real time voltage is shown, afaik. real time current is not.

I already have more chargers and charge slots than batteries, so I might not be willing to get another one. Let’s see.

What do you use for tracking?

It’s a peculiarity. My home country’s postal service came to some sort of agreement with chinese logistics company, thus trackable and relatively fast shipping is available to us for cheap to nothing.

Aliexpress emailed tracking info: “Parcel Status Arrived in destination country; awaiting customs clearance.” It will be interesting to see if there will be further tracking info, and how long it will take until final delivery.

With the listed sale price at <3bux, I figure I’ll pull the trigger on a few. It’s nice to be able to see the realtime voltage as it’s charging, but not have to drag along an Opus or almighty Miboxer to work if I just want to top off a cell.

I keep a 100B in my bag just in case, but only 4 LEDs doesn’t say much. Being able to pull it when it hits, say, 4.1V or even 4.0V would be nice.

Technically, if you pull the cell just upon voltmeter hitting somewhere near maximum voltage, since charging current will still be close to 1A/0.5A it can be grossly predicted that final cell voltage would lay around where you want. Voltage differential dV ≈ I × R, where I is the remaining charging current and R is the sum of cell plus rail contact plus other resistances.

For ePacket shipments, the USPS tracking system will now even show status beginning with acceptance in China. One of the random Chinese tracking sites will give greater detail when it’s inside the China Post system, but aside from that, the USPS will have it covered from start to finish.

The trip across the pond actually takes only a few days. Once it reaches the states, it has to be processed through one of USPS’ International Service Centers, which can seemingly take forever (and often a source of complaint), then onto the local regional distribution center and final post office for delivery.

I made a video (it’s boring, probably go to Youtube Settings and playback at 2x speed)

It doesn’t show real-time charging current, but shows real-time voltage (not sure how accurate, but at least more granularity than the 0-25-50-75-100% LED bars of other chargers)

Excellent video, many thanks for sharing it!
I guess the real-time voltage display is useful.

Just a heads up – if you order 2 the price is even lower (2.66 $US each)

Is the sale still active?

I’m not seeing the sale price on Aliexpress.

I believe the sale for the item I linked is no longer active or no longer visible. Maybe it was the wrong price, maybe it was for a limited time or for a limited amount of stock.

My order says “awaiting shipment”.

it’s gone for 2.80$, back to 7.99$…i am thinking about it, but i am still using eneloops only, lion seems like a lot of work and precautions…don’t overcharge, don’t overdischarge, check the voltage, put them at 3.7V for storage, what to use- protected or unprotected, avoid short circuit, avoid drops, it’s getting harder and harder to order them online, it looks like full time job taking care of lion batteries… Shocked

That was a quick sale then.
But congrats to the people who were able to get the deal.

The store’s sale item page still falsely lists them for $2.80, but clicking on the link to the item page reveals the regular $7.99 price.

The listing also indicates that just over 200 orders have been placed since January 15th, and there are still 1500+ available.

Whatever quantity they were willing to sell for $2.80, it wasn’t many.

Add the convoluted way this store does its listings, and how the AE site operates in general, it’s definitely caveat emptor.

To add confusion, Liitokala apparently operates several “official” store fronts on AE?

https://www.aliexpress.com/store/1823237
https://www.aliexpress.com/store/bigsale/217753_224021.html
https://www.aliexpress.com/store/1045132

Or are these all resellers claiming to be official? Guess we’ll never know…

Yeah, I noticed that earlier in the week.

Liitokala’s own site links to “https://liitokala.aliexpress.com/” which is the “Liitokala Official Flagship Store” I’ve also seen one with Hong Kong in the URL.

I’ve read that the best way to ID, if not necessarily discern between different stores is to look at the store ID number, but it wouldn’t surprise me if sellers operate multiple stores. In buying other stuff from AE, I’ve long suspected that is the case, without even considering the amount of image/listing stealing that occurs.

It all seems kinda sketchy, but it comes with the territory I suppose. Cheap stuff is hard to resist sometimes, but the risk is there.

I just wonder why, even if for their own sanity, why the sellers don’t just create a single listing for each product, instead of multiple listings, some crammed with entirely disparate items, resulting in lots of duplicates and potential confusion for shoppers.

I had a couple of the S1s in my cart, but entirely forgot about the timing of the sale. I wouldn’t have minded getting a couple to play with at that price, but as a consumer, I no longer feel the need to play games to save a few bucks, and these kinds of tactics on the part of LK don’t encourage me to look to them again in the future. I’d rather deal with someone like Simon at Convoy, who is still saddled with the same deficiencies of AE’s site, but at least operates in an upstanding manner.

Back to your regularly scheduled program…

as far as i can tell, this morning while they’re still at sale for 2.80$ i spotted only 125 items for sale in stock…since all 125 pieces were sold, sale is ended…it’s typical for many ae sellers, only small batch is actually for sale…

Mine came today and I’m charging my first battery. So far it seems to work well. Right now the built in display reads 10mv lower than my Fluke 189. I’ll check the voltage when it terminates.
