Features cell polarity detection and does away with the powerbank function.

Price seems cooked right now. 
Cheers my dears :-)
Interesting 
I already modded my lii-100’s with voltmeters so I will wait for price drop.
From what I see in the picture it displays current. We'll see if this is just a cosmetic current 
selection indicator or an actual converted current shunt voltage drop reading 
(displayed value would progressively drop after entering CV charging phase).
Cheers my dears ^:)
I missed that.
If it’s real value it would be great.
Thanks for the heads-up Barkutti, seems pretty nice and “ergonomic” 
We need a comprehensive review.
Lii-S1 spotted at Banggood Bangbad. I do not really want to judge but hell with the $9.99 jacked up pricing, in AliExpress I see it for $7.99 with fast and trackable shipping. 
Cheers 
I’m sure the current display is not a real reading, that feature alone would cost the same as the charger tiself
Well I don’t know, but the Opus BT-C100 has a decreasing current in the CV phase on the display. It costs like $3 more.
If the end voltage is a bit lower than with the Lii-100, we might have a new winner. I like the build quality of the Lii-100 much more than any Opus or Xtar charger. The springs are smooth and it can charge NiMHs just fine. The cell polarity detection sounds like a nice feature as well.
Personally, I wouldn’t mind paying ~$10 if it’s an overall better successor to the Lii-100.
Nothing beats a $0.99 original Lii-100. 
thanks for highlighting this product! very interesting evolution of a beloved charger.
Price is crazy, obviously, guess we have to wait for a flash sale or code. 4.99-5.99 would be a good price point.
Looks good would be great if the too high charging voltage of the Lii100 is fixed.
I think the same actually.
Both will charge the battery and then finish charging and this is it.
But if one needs some more diagnostic, etc… there are the others, more capable but still cheap ($12 - $15) chargers like 2-bay Lii-300 or 4-bay Lii-500.
Well, nothing beats the price. It’s definitely a great travel size charger and the price wouldn’t cause me grief if it were forgotten or lost. That’s not the case with the S1 at current prices.

Displaying the current value is as easy as reading the sense resistor voltage drop and displaying the corresponding I = Vsense / Rsense value, no big fuzz really. Just matter of a few extra lines of microcontroller code any widespread and cheap multimeter already has. Actual weighted per unit cost: negligible.
Cheers ^:)
There are really a whole bunch of chargers. What sets the Lii-100 apart from the rest is the occasional stupid low price with code. The display will simply increase cost, so I cannot imagine this charger being as cheap as the original, so it looses its primary advantage.
I really love a voltage display, but to me this is initially of interest if I charge multiple cells at once from one light to check if the cells have discharged evenly. So for a single cell this is of no interest.
Nevertheless, it is a good looking charger, and it still is cheap. Certainly will keep an eye on this one nevertheless. :sunglasses:
It is if you want to stop charging at, say, 3.6V for storage.
…and the cost of display?
Have a doubt it is measured value though, why else show the rounded up value of 0.5A, namely 0.5A?
So, if the display showing either 0.1A or 0.5A is all the benefit, then…
Voltage reading I find not as important as amps
That combined with automatic stopping of charging would make sense, otherwise…
…yeah, and the power bank thing on Lii-100 tends to stop working in some circumstances anyway
