500mA is about perfect for AAA NiMH cells.
However, for smaller lithium-ion cells(10440), it’s pushing it a bit.
Warning: off-topic, but still relevant to BG purchases.
Yea, I’ve noticed this new “behavior” just over the past week or two. It’s ridiculous and probably not even profitable, since it gives customers a shock when they see the checkout price and they may simply cancel the order out of annoyance.
I added a $12 item to my cart and the default shipping charge was over $14. Do they think that such a tactic will sell more products? I felt slightly angry and highly insulted, which I wouldn’t consider to be an effective business strategy.
This is hopefully a programming or configuration error, but if not then it’s just Banggood being Banggood.

I know what you mean, when I first saw that I thought… “do they really think ‘we’ are that stupid”? 
I think they’re hoping we wouldn’t notice.
The flip side is they probably have just as many newbies who order and expect their item in 2-3 days. In those cases defaulting to faster shipping would reduce a lot of customer service issues.
What voltage for lion does this charger terminate?
I hope under 4.2
I ruined my opus I need a new charger
My old one does. About 4.18V - 4.2V, depending on battery.
Just curious… how did you “ruin your opus”??
Perfect,
Inserted a cell backwards. It fried it.
…… Ouch, that sux. 
On that topic, for those who already own Lii-500 and are now getting the Lii-500S, battery direction has been reversed. But at least the charger is supposed to have reverse insertion protection.
I how to never need the protection again haha
Thanks, I ordered one
It’s good they put the direction back to “normal” on their new version.
However, I’ve accidentally put cell in backwards in the old Lii-500, and it just refused to charge. It didn’t fry anything.
Thank you for the deal, I just placed my order!
Can it load longer cells than lii-500?
I handles 21700 supposedly.
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.
