Hi everyone,
I would like to have universal charger for many types of batteries.
Most of the time I will be using it with NiMH AA/AAA.
Out of these 3:
1. Xtar VC4
2. Opus BT-C3100 V2.2
3. LiitoKala Engineer Lii-500
Which one will be performing best? (Best for NiMH everyday charging)
I would appricite your help.
I’ve read many reviews, but still can’t make that decision

I’ll add one other option. If you’re looking for an inexpensive charger for AA and AAA NiMH cells, that does a good job, look for the Panasonic BQ-CC17 charger that often comes bundled with Eneloop batteries, found in places like Costco. It’s slow, but is a smart charger with individual channel charging. Supports 1-4 AA or AAA cells charging in any configuration. For a cheap charger, it’s very good.
^ Thanks for your comment, looks like it is nice charger - however it will not suit my needs.
Most of my devices are powered by AA/AAA however I also have flashlights that run on 18650
Buy Maha mh-c9000, mother of all chargers.
If ALL you care about is charging, the Xtar is simple and works fine. I have one and use it frequently. It may charge a bit fast at 0.5A for AAA but I haven’t had any problems.
If you want to be able to do some cell analyzing, cycling, and have a LOT more control over HOW you charge the Opus is a clear winner. I have one and use it a lot for both charging and more advanced functions. Since I got this one I hardly use my hobby charger.
The LiitoKala Engineer Lii-500 looks pretty comparable to the Opus but I’m not personally familiar with it. Both it and the Opus are a cut above the Xtar.
