Great!
So does the setting stay even after you power it off or does it revert to the display off after 15 sec. again? (Canāt try it myself because I havenāt received it yet).
Perhaps there is but itās not in the manual.
Try every single long keypress and key combination you can think of and let us know if youāve succeeded.
Might as well be something like:
Press channel 1 button 68 times, then put your left pinky toe on the mode button while holding the Current button with your tongue for 2 minutes.
Just a warning to anybody that wants to get a Lii-500s. It doesnāt measure and display the internal resistance of the batteries. I know that function didnāt work good enough in the Lii-500.
If youāre reading the charger reviews on lygte-info.dk youāll see that especially the lower priced chargers hardly ever do a good job when it comes to reading resistance.
I think they made a good decision by leaving it out instead of keeping the feature while itās not working.
so what should i buy ? the 500 or the 500S there is sooooo much information in this thread for experts that non experts dosent understand or should i choose another charger ?
Depends what you need.
If you donāt need discharge and test modes and are just looking for a decent charger then you might as well buy a more simple charger.
But for $21.90 including shipping the 500S is a great deal.
Iām very happy with it.
If you donāt need to test cell capacities then there are many simpler chargers available, including some from Liitokala. However, if you do want to measure capacity then either the 500 or 500S will work just fine and are probably the least expensive analyzing chargers you will find.
Both chargers have similar functionality, but the 500S will also discharge a cell and stop, which was a feature that I really needed, but am unable to do with my Lii-500 . I missed the newer model by just 3 months or so.
If you donāt need to discharge batteries (most people donāt), then the 500 is great and is slightly less expensive (ignoring coupon codes). If you want a fast 2-amp charge rate and a Discharge mode, then the 500S is a better choice. I donāt like the āinverseā display or the touch buttons on the 500S, but I would still choose it over the 500 if the price were right.
Non-experts might prefer a charger that doesnāt offer a selectable charge rate, however, since some batteries should not be charged at 2 amps. If that sentence is gibberish to you, then I recommend getting a simple charger that has no user settings and has only colored LEDās to indicate either āchargingā or āfinishedā. Lithium-ion charging circuits are ubiquitous in Chinese manufacturing today and thus even some of the least expensive chargers available will work just fine and operate safely.
I would choose 500S as it has temperature sensors to prevent overheating and supports charging 21700 cells. These cells will become much more common than today. No doubt you will need a 21700 charger. Other chargers can be Miboxer C4-12 and BLF UC4 Also Liitokala Lii-402 will in not long time be upgraded to fit 21700s.
