Not that I needed another charger, I ordered one because I’m a boy who loves his toys.

I’m wondering about the 3 operating modes: “CHARGE, DISCHARGE and TEST modes”.
I don’t suppose we’ll get an answer unless someone finally gets the unit to test.
To recap, the old Lii-500 Engr has Charge, Fast Test and Nor Test.
“Charge” does what it says: charge to Full.
“Fast Test” will discharge the battery to Empty (around 2.80v for the Lii-500), then will start charging to Full, measuring the Charged Capacity along the way.
“Nor Test” will first charge the battery to Full, then will Discharge the battery to Empty (around 2.8v), and report the Discharged Capacity; as a final step, the Lii-500 will also fully charge the battery after it has fully discharged the battery (the user can remove the battery any time after the Discharged Capacity is shown, if he doesn’t need the battery charged to Full,)
For the Lii-500S:
“Charge” likely works similarly: charge to Full (4.20v for Li-Ion)
“Discharge” = I wonder what this means — is it another name for the previous “Fast Test”, or can it possibly work like the “Discharge” function of the Opus BT-C3100? (ie. discharge battery from whatever state (can be in “not Full” state, at least for the Opus BT-C3100) and then display the Discharged Capacity?
“Test” = I would presume this works the same as the previous “NOR Test” = first charge to Full, then Discharge to a pre-set Empty voltage (probably around 2.8v), report the measured capacity, then Charge back up to Full.
I just got a email from banggood that the charger is out of stock.
Received my shipping notice today. Expected delivery in about two weeks.
It was not in stock when I ordered mine. It was estimated to be back in stock around 18 June.
Mine still says “processing”
Mine too. If I click the “blue Processing” it takes me to the order. It says shipment is estimated to be 18 June. We shall see…. 
The coupon doesn’t seem to work anymore. It says “This coupon is not available for limited offer products”
Promotion Sale From June 10 to June 16. - that disables my discount
Ordered early on in deal, but out of stock email came today 
Did they cancel your order? Last time I got out of an out stock message they offered the choice for refund or wait for restock
I got an “Out of Stock email” yesterday, IIRC. It gave three choices…
- 1. Wait
- 2. Change to another product
- 3. Full Refund
Being the patient type & wanting the charger…. I chose “WAIT”. .
I got the same thing twice. One last week which I said I will wait, and one yesterday which I answered with the same response. What the hell is going on over there?
I already sent banggood a message to get a date when it's back in stock.
Yeah… I got two emails also… about 8 hours apart. 
I also answered both & sent them a message from my account too.
I figure the price we paid is worth the wait. As I said a while back, mine was not ‘scheduled’ to be processed until 18 June anyway.
So I figure it will be before to long.
Martin said he has asked…. he will probably get a pretty definate answer as to when they will be in stock again. 
Received my charger today. Great charger! Love the display. Easy to learn the user interface. I’m sure I’ll get a lot of use out of it.
I am interested to see a review by someone who has the time to carefully test the ability of this charger to adequately fill NiMH cells without overcharging them. I know this will be my go-to charger for Li-ions, at least, and possibly also NiMH, if it seems to do a decent job at filling those safely, as well.
Congrats!! 
. When did you order??
banggood told me that a batch will be sent today..
