[M4D deal ACTIVE] LiitoKala Lii-500S groupbuy

This one can discharge batteries.

My tracking # works now. I’m a happy camper at this moment.

The valid range is 4.15v - 4.25v. But, I like it to be on the lower end of that range. It’s sometimes tough to tell, exactly, since (as you say) cells will drop their voltage 10mV or 20mV pretty fast when they’re done charging.

Most of my chargers seem to result in voltages around 4.18v when I take them off the charger. So, I suspect they’re actually being charged to 4.20v at the point of termination. Most chargers usually terminate the CV phase when they’re only putting in about 100mA of charge to the cell to hold it at 4.20v.

I found this thread b/c I already own a Lii-500 charger and wondered if there was a newer version. So I have a couple of questions for those who have received the Lii-500S.

I have a problem with my Lii-500 charging 16340 batteries. There isn’t enough spring tension in the rack and so often the battery doesn’t register. Have they fixed this issue on the Lii-500S?

I see the Lii-500S like the Lii-500 doesn’t charge all 4 bays at full charge. When only 2 bays are used they get full power but when 4 bays are full they step down the charge.

I own a couple of Xtar 18700 batteries and they fit in the Lii-500 but it is tight.

I also own a Nitecore D2 which used to charge to my batteries to 4.22 but on the newest 3000+ 18650s and 1100+18350s it only charges to 4.20. But if I put them into the Lii-500 they only sit in the charger for less than a minute and it registers 4.22 and then shows finished. I can’t explain why the D2 doesn’t go to 4.22 on these newest batteries.

Thanks

My early model lii 500 always shows 4.22 on the screen but only shows 4.19 - 4.18 on my DMM. The measurement must be under load.

It says coupon expired.

I’d like to get one also. Been waiting for the sale to end so I can use the GB code.

Edit-Code expired when I tried also.

I request a new deal

Hi M4d M4x. Is there a new coupon available? Or do we have to wait for the banggood current sale for the charger to end first.

yes

we need to wait after that my code works again

(if not I request a new)

Personally not a big fan of negative LCDs, they are more difficult to read. Plus that beep every time a button is pushed seems super annoying. I hope it can be turned off.

Did Banggood extend their sale? Knew I should have ordered this when it first started. Going to take forever to get this charger.

I’m waiting also, roar!!!

Guess we will wait till the 12th.

I wish they had not dropped the 300ma mode. I use this for 10440’s as I would hate to hit them with 500ma. Have not decided yet if I will try this one or not.

Got mine! I like it. I didn’t know about the negative display but it’s not a dealbreaker. So far so good, fits the 26650s pretty good.

Got mine today as well. The display is very readable even at a shallow angle when the backlight is on, but when it’s off, you can barely see anything. I wish it could leave the backlight on constantly or only go 50% rather than completely dark. I also got the cheaper LII-S4 and it’s not battery polarity sensitive, while this one is.

Banggood is not going to relinquish this sale so that the discount code will work. Was supposed to end on the 12th. guess they are selling a lot of them at $25.

I’m bummed I missed the discount deal… $21.99 is a nice price. Can’t find it any lower than $29.99. I’m not in a hurry so will wait. Hopefully someone will bump the topic with another good price later on.

A small resistor should fix that. I’ve seen people do it on chargers before. Place it between the backlight FET’s drain and source. When the charger commands the back light on you have full brightness, when it doesn’t you have partial brightness (depending on resistor value).
