LiitoKala lii-500S - New HIT or ...?

  1. The overall user consciousness in these matters is lacking. The high charging voltage is probably partly motivated to show “correctly blown up” figures in the capacity tests. Even if not for everyone, take a peek here: DIY: Generic way to lower voltage termination on li-ion chargers.
  2. ¯\_(ツ)_/¯ (I also can't say I like it).
  3. The original Lii-500's implementation was botchy. I still prefer to have it as it lets me know if there is something wrong in the rail or cell contacts (rust, debris, etc.), yet I know what is going on and don't complain. Other users just complain and shite happens.
  4. Like putting your canary housepet on a diet halving his seeds to save money. I really wish for they to stop with this endemic electronic bull$#%&@. Really. :-|

I live with it but I hate my multimeter auto-power off feature.

Why is that a negative?
The channel LED color will show charging (red) or finished (green).
The screen doesn’t need to stay on all the time. Only when you put in a battery or when you need to check progress. You don’t sit down in front of your washing machine for 2 hours to see what’s going on either. Or do you? :wink:

In Lii-500 at any time it was possible to see indications on the display without pressing buttons. In all chargers Miboxer is done in the same way - information is visible at any time of the charge, only the screen backlight goes out.

I love passing by to look at the charge process. Who doesn’t need all this, he buys for $ 2 a charger with two bulbs - red and green.

Ball-busting stuff Mishanchik. Looks like LiitoKala is run by a gang of ball busters LoL. :-D

Jokes aside, it surprises me why certain decisions are taken (how the screen goes off for your viewing pleasure): https://youtu.be/OeqbAeqGn5E?t=399

Is there a need to save a ridiculous amount of power in a device meant to be plugged?

In any case, is there any sensical reason to deprive electronic devices from hidden switches or special menus meant to please advanced users by removing their retarded and restrictive annoyances? No need to tell me “warranty voided”, as far as I am concerned they could even stick the warranty paperwork up their arses at the very factory in exchange for all sorts of power user options.

This charger displays info for 1 slot at a time. So without pressing a button you could never glance at the charge status of all 4 channels anyway.
Mind you, I’d rather had a choice for display on/off as well. Like I still wish I could turn off the backlight of my Maha MH-C9000. The damn thing lights up the whole room at night.
I’m not sure though if the 500S completely turns off the display or just the backlight. If it’s just the backlight it might be fixed by soldering the backlight to a terminal on the board that’s powered all the time.

Sure you can fix that, c'mon. With a piece of dark cardboard, a small glass cleaning cloth or something similar.

I find touching a button to turn on the display far more elegant than having to cover the display with cardboard or a cloth to “turn it off”. :sunglasses:

You like modding, don't you? I am sure that is an easy mod. If you take some good photographs of the C-9000's LCD control mainboard it is very very likely some backlight controlling MOSFET will be found. Cutting down its gate line and placing a small SPST switch or self-locking pushbutton in between gets the job done or should be so.

You’re right Barkuti.
But my priority will be finding how the 500S is shutting down the display. I”m hoping it just turns off the backlight. Should be an easy fix.

Thank you Barkuti. It’s a good reminder to read the full thread before buying 2 of them with the first code one reads:-) Your link is still cheaper.

No this is still the best deal:

That’s why I consider my Opus BT-3100 so far the best-designed of them all. Long press (5 sec) the ‘Display’ button if you want the backlight to be ON all the time, otherwise, it stays off YET the LCD screen shows ALL channels doing their thing all the time. Beautiful UI, I should say.

Should be. The Lii-500's display backlight also works briefly, but as it is a classic passive LCD it has good visibility without backlight. On the other hand the new Lii-500S display looks nice, features a bigger screen with some senseless fancy graphics and stingy information for its size. If you are right the Lii-500S display will have an easy fix like this one meant for the Lii-500 (check Q35 with a gate voltage injecting resistor, I made it with 470Ω; the smaller the closer the brightness is to standard):

This is

LiitoKala Lii-500S
Long press (2 sec) the 1-4 button to keep the backlight on or off.

Thanks for sharing. Where did you get that from?
It’s not mentioned in the online manual.

lucky guess…

Translation: out of desperate fiddling with the device and just before hitting it with a hammer. O:)

Great!
So does the setting stay even after you power it off or does it revert to the display off after 15 sec. again? (Can’t try it myself because I haven’t received it yet).

:smiley:

No,500s will not save setting.
