with the BLF Q8 on its way, im considering a new 4 slot charger. It should be solid quality, reliable model “analytical” charger, without any known issues able to charge most of the common batteries, including the 20700 and 21700 type.
At the moment im checking out the XTAR VC4 or some of the Nitecore models, your suggestions are welcome.
As suggested, the Opus BT-3100/3400 v. 2.2, or v. 3.1.

The Xtar Dragon Plus.
The Gyrfalcon ALL-44.
Among others.

ETA:
I’m an Xtar fan-boy and have 10 chargers and their USB meter. I also have the VC4 charger. It’s a decent charger, running on a positive 2.1A/2.4A wall wart. It’s slow with four slots charging at once. I get missed terminations on my sample and now leave it at my girlfriend’s place, for the lights I leave there.
I have about 25 common consumer chargers here and was looking at the G-44 (casually evidently, lol) and thought that it was a good charger, but it does no analyzing?
I have only used the Nitecore D4 and while I cant say its the best, I can say that it is accurate in reading volts (tested with multiple multimeters), can take IMR, Li-ion, LiFepo4 Ni-MH and NiCd cells which is good for me because I have a few different cells in my collection.
It also includes all the norms that you would expect from a ‘smart’ charger like reverse polarity protection and over voltage protection etc…
It would be good to note that while it is a 4 slot charger, it can only charge two 26650 cells at a time due to their size.
The D4 seems popular, but I saw that it has only 375 mAmp charging current per slot, when charging 4 batteries at once. It also does not specify, that it supports the 20700 and 21700 types.
You can’t go wrong with a SKYRC MC3000 (officially supports the xx700 sizes - and has a few nice features, which other chargers are missing, e.g. adjustable termination conditions).
