I don’t know exactly what the right IR is but all my new cells were high in the Miboxer. They do need to tweak something .

Best would be to keep an eye on the internal resistance indicated in the charger. Make sure it is as low as possible by cleaning all contact areas before and by turning, re-inserting or dangling the battery in the charging slot until you get a reasonable number on the display. Once you have values of 200-999mOhms you don’t have to expect this charger to auto set the current to 3A. My C4-12 had real problems with button top cells and I got values between 320 to 999mOhms, i.e. a pre-selected charge rate of 0.00-0.15A.

All I ever did is pushing/twisting cells until I saw the lighting symbol in the display.
So the reason it charges slowly could be twofold:
- Bad contact.
- It’s just working but I just have to wait a few more minutes until the intelligence of the charger ramps up the amps.

What’s a reasonable Ohm range?

I really would like an upgrade that keeps the settings at 3A permanently. All cells I charge in it are 3500+ mAh.
Now I have to play with the settings every time I put in a cell.

No, we can’t alter it.

Why do you have to manually set it every time? Usually my Liitokala 26650 cells auto set to 2.90A or 3A anyway. Setting them manually is not that big a deal and is normal for all chargers.

It would not be considered safe to program it to automatically choose the 3A setting for every battery. No battery charger uses 3A as the default setting.

I bought this charger especially for 26650 cells, so they don’t take long to charge.
It was the 3A rating I bought this charger for, but when I put in a 26650 cell and check the amps it usually is charging with 0.7-1.5 amps.

Which Liitokala charger auto sets to 3A?


None, that would be too dangerous.

I have Liitokala chargers that I can set to 0.5A, 1A and 2A.
At least the indicator light stays permanently on those values. Obviously that’s no proof the charger actually uses those currents. I never use such cells but 2A would cook 900mAh cells.

Anyway my question was a bit unclear I think.
Which Liitokala charger has 3A output? I haven’t found one above 2A. And that’s for all cells combined. So only if there is one cell in the charger it gets 2A.

The only Liitokala charger I know that charges 2A is the Lii-402 only when used with single battery on the slot #4 and using a USB charger that can provide 2A.
I’m not sure of any others Liitokala charger that can charge at 2A.. maybe someone can comment?

The charger has a 12v 5A input.
I’m looking for a cable so I can plug it in my car.
Any advise where to buy such a cable?

I’m pretty sure none of the Liitokala chargers can do 3A. Why are you thinking they made a high amp charger?

For an unprotected 26650 high drain battery, under 50 milliohms is good.

My cyan and black Liitokala 26650 typically read 30 to 40 milliohms.

Because I’ve misread your message…. Sad

It’s about Liitokala cells being charged at 3A, instead of a Liitokala charger charging cells at 3A…

Okay, now I understand.

This C4-12 is the first charger I’ve seen with this much power, 12A. Maybe it will start a trend where other charger manufacturers will release high powered versions of their current models. Then we will have choices. Thumbs Up
