Even the protected ones?
I can’t imagine, how even the unprotected fits, as not all the pins can be moved to the end of the charger. At least on my MC3000.
I would not rule out an MC3000 because you are worried about a non tech person using it. Just assign the charge programs for the batteries they are going to charge to one of the short cut keys. Then it becomes a two key press operation to charge the batteries. The current firmware allows for 8 short cut key assignments. I made up a cheat sheet for my wife and she uses the chargers all the time. I think by now she has the key press sequence memorized. I set them up to be up+1 is AAA white, up+2 is AA white and up+3 is AA black. Also unprotected 21700’s fit fine. I don’t own any protected 21700, however for sure I would not count on them fitting.

Is there a good video or review that explains the MC3000? I checked out Youtube but all useless they mention Modes: Dummy; Simple; Advanced but do not explain what any of these modes are. I keep seeing mention of a cheat cheat but I don’t even understand why a cheat sheet is needed just how complex is this unit?
The user guide has its flaws also. I will have take notes when to click, when to press (long click) a button …
In short:
Dummy mode: only NiMH and LiIon. You can set up in the settings the charging properties, after that you show in the batteries, and it will charge them.
Simple and Advanced: you can create programs to charge the batteries: chemistry, charging/discharging current, etc. Simple means you can change less settings. In this mode, you put in your batteries, select the program you like per channel, and press start to charge.
The difficult part is to find the settings for the programs you need. After you set up the programs, it is almost dead simple to use it.
Wow… if they have BT capability why don’t they have a config dump and just have default configs users can download that support all types? Seems they are wasting the capabilities of this unit.
Stop … right … there 
The BT is a joke. You just get an animation, instead of a visualisation how much you battery charged. Let alone, that sometimes you can’t even connect to the charger.
Maybe, I will take a closer look on that app, but it is not the best. Same for the windows program. I use the DataExplorer instead, to monitor, what happens in the charger.
This is a very capable charger, but the user interface in the charger, through BT or usb is a joke sometimes.
Ok MC3000 is out my mother is 82 years old and to press more then one button to start charging is too much… Especially if it’s so expensive and they have not improved on the UI or set default battery charging.
So focusing on the main 3 of my requirements the others were just a plus and not absolutely necessary.
LiitoKala Lii-500
Miboxer C8 or C4-12
Opus BT - C3100 V2.2
Xtar Dragon VP4 Plus
These are all chargers I can purchase in US either from BangGood or Amazon. I want to purchase from US either Amazon or a site that uses Paypal for payment. So if the MC3000 or Dragon did not exist what charger would you order that has the most of the features for the money?
From the US?
As I’ve said before, the Folomov A4:
Or the C4-12:
https://www.amazon.com/Universal-Battery-Charger-Miboxer-Rechargeable/dp/B07HF43M7V/
Both are great chargers, and if the MC3000 weren’t available, I’d go with either of them, and probably the A4, since it has a more intuitive multi-button UI and support for LiFePO4.
From your list of interesting:
1. “Upgrade” Miboxer C4-12 with Li 4.35 and LiFePO4 ( The old version has a bunch of children’s sores with charging slots and springs )
2. Miboxer C8
3. Xtar Dragon VP4 Plus
Ok will order the Miboxer C4-12 then. Thanks for the advice.
Buy only new version - “Upgrade C4-12” with two yellow button!!!
Old version have frequent problem with springs, dying third slot, not support: 21700 protected, LiFePO4, Li 4.35
Ok got it. BTW what is the difference in the C4 v3 and the C4-12 they both look exactly the same. Are they the same but maybe just a different numbering for Amazon as on Amazon I only find the C4 v3.
Thanks
This is the only place where I found a new “Upgrade C4-12”
Get a analyzing charger for yourself and a cheap trustable charger for your mother. I hardly use my opus cause it’s a big noisy block, I replaced it with gryfalcon 88 for just charging my cells. Even though the gryfalcon has 8bays as opposed to 4 it still looks smaller and makes a lot let noise then my opus. A Littokala can be bought pretty cheap depending on the amount of bays.
The Opus BT-C3100 fits unprotected 21700’s just fine
Neither one of those is an analyzing charger
You* REALLY* do want an analyzing charger. If you don’t now, you WILL later, I guarantee it.
There is no ‘perfect’ charger. Decide what is important, pick a charger and go on.
What is the difference in an Analyzing charger? I thought they all did the same the C4-12 and Opus BT. But if that is not the case the only one that I see that qualifies in my price range, found in US would be the Opus BT-3100 V2.2 as I can get that on Amazon.
Analyzing charger can more accurately measure cell capacity
by using a discharge test.
Opus 3100 can do that. Miboxer c4-12 cannot.
An analyzing charger will charge > discharge > the charge the battery and give you the capacity determined from DISCHARGE. This is the only accurate way to measure capacity.
Lii-500, Zanflare C4, and the Opus BT-C1000 are analyzing chargers.
The main advantage of the Opus is more control and options for charging and discharging. It has some ‘quirks’ that some people dislike. But, it IS more flexible, more powerful, and has more charging options.
A ‘charge only’ charger cannot do this.
The Miboxer C4-12 appears to be only a charger, but a good one. It’s fine if you don’t really want an analyzing charger. But I think you will.
