Nice, good looking charger with lot of power 0.5A - 2A (2A for 2 batteries 0.5 - 1A for 4 batteries)
Some people might miss discharging function for older battery types (with memory effect)
I’m very satisfied tho.
Having had my Luc V6 for quite a while, and having no issues with it, I needed a new charger for 21700 batteries and found this new Luc v4 elite on the site. It's brilliant, nice clear display, with adjustable charge rate, fits 2 21700's easily and at a good price.
